Posts Tagged ‘The brain’

A few years ago I was fortunate to be chosen to attend a day “course” on creativity and the whole brain. I really enjoyed the course and Dr Kobus Neethling (read about him at the bottom of my post) was expected to be there, but he was held up and we had only his videos to watch however, we were fortunate too to have brilliant speakers to lead the day. We had to do all sorts of activities and one “test” results pointed out that I was a “whole-brain”-person. They say that you should strive to use your whole brain. I’m not always sure if I really use my “whole brain”…e.g. today, I’m really in a lazy mood and I think I don’t want to use my brain at all! Picasso was also a “whole brain”-thinker! I’ve found this fun website where you can create your own “Picasso”!  THIS LINK to create your own Picasso!

Whole Brain Thinking
What is WHOLE BRAIN THINKING? Whole Brain thinking is when the two cerebral hemispheres of the brain unify to create a “whole brain thinking” pattern. Using whole brain thinking enhances living, logic, intuition, analytical skills, mechanical reasoning and artistic ability.
Whole brain thinking, essentially enriches brain functioning to a superior level of heightened awareness. To better understand the effects of whole brain thinking, read on:

Left Brain thinkers are often engineers and scientists; Right brain thinkers are most often artists and poets. In overview, left brain thinkers use structured analysis in their thought patterns; right brain thinkers use patterned recognition in their thought patterns. When both are combined, intuition is the ultimate achievement of the two. Clarification of whole brain thinking is that persons who use whole brain thinking have the ability not only to be creative in the arts, but could possibly fix a diesel truck engine as well. By using whole brain thinking, the impossible becomes possible.

Some of the world’s greatest pioneers, inventors and leaders use whole brain thinking. Leonardo da Vinci was not only a fine artist but a great scientist as well. Frederic Bartholdi, creator of the Statue of Liberty, utilized whole brain thinking — not only did he create the Statue of Liberty, he also engineered the scientific dimensions of his creation.

The four thinking styles in the Whole Brain Model are:

1. Logician: Analytical, Mathematical, Technical and Problem Solving.
2. Organiser: Controlled, Conservative, Planned, Organised and Administrative in nature.
3. Communicator: Interpersonal, Emotional, Musical, Spiritual and the “talker” modes.
4. Visionary: Imaginative, Synthesizing, Artistic, Holistic and Conceptual modes.

Dr Kobus Neethling is the President of the South African Creativity Foundation. In 1998 he received “The Distinguished Leader Award” from the International Creative Problem Solving Institute and the Creative Education Foundation: The most prestigious creativity award in the world.

He is also the founder and Director of the South African Creativity Foundation and the Kobus Neethling Group. He holds 6 University degrees (Cape Town, Potchefstroom and Georgia USA), including two Master’s Degrees, a Doctorate and a Post Doctorate (Cum Laude).

The Human Brain – With one hundred billion nerve cells, the complexity is mind-boggling. Learn more in our cutting edge special report. The brain is the most complex organ in the human body. It produces our every thought, action, memory, feeling and experience of the world. This jelly-like mass of tissue, weighing in at around 1.4 kilograms, contains a staggering one hundred billion nerve cells, or neurons.

The complexity of the connectivity between these cells is mind-boggling. Each neuron can make contact with thousands or even tens of thousands of others, via tiny structures called synapses. Our brains form a million new connections for every second of our lives. The pattern and strength of the connections is constantly changing and no two brains are alike. It is in these changing connections that memories are stored, habits learned and personalities shaped, by reinforcing certain patterns of brain activity, and losing others.

Grey matter
While people often speak of their “grey matter”, the brain also contains white matter. The grey matter is the cell bodies of the neurons, while the white matter is the branching network of thread-like tendrils – called dendrites and axons – that spread out from the cell bodies to connect to other neurons.

But the brain also has another, even more numerous type of cell, called glial cells. These outnumber neurons ten times over. Once thought to be support cells, they are now known to amplify neural signals and to be as important as neurons in mental calculations. There are many different types of neuron, only one of which is unique to humans and the other great apes, the so called spindle cells.

Brain structure is shaped partly by genes, but largely by experience. Only relatively recently it was discovered that new brain cells are being born throughout our lives – a process called neurogenesis. The brain has bursts of growth and then periods of consolidation, when excess connections are pruned. The most notable bursts are in the first two or three years of life, during puberty, and also a final burst in young adulthood.

How a brain ages also depends on genes and lifestyle too. Exercising the brain and giving it the right diet can be just as important as it is for the rest of the body.

Chemical messengers
The neurons in our brains communicate in a variety of ways. Signals pass between them by the release and capture of neurotransmitter and neuromodulator chemicals, such as glutamate, dopamine, acetylcholine, noradrenalin, serotonin and endorphins.

Some neurochemicals work in the synapse, passing specific messages from release sites to collection sites, called receptors. Others also spread their influence more widely, like a radio signal, making whole brain regions more or less sensitive.

These neurochemicals are so important that deficiencies in them are linked to certain diseases. For example, a loss of dopamine in the basal ganglia, which control movements, leads to Parkinson’s disease. It can also increase susceptibility to addiction because it mediates our sensations of reward and pleasure.

Similarly, a deficiency in serotonin, used by regions involved in emotion, can be linked to depression or mood disorders, and the loss of acetylcholine in the cerebral cortex is characteristic of Alzheimer’s disease.

Brain scanning
Within individual neurons, signals are formed by electrochemical pulses. Collectively, this electrical activity can be detected outside the scalp by an electroencephalogram (EEG).

These signals have wave-like patterns, which scientists classify from alpha (common while we are relaxing or sleeping), through to gamma (active thought). When this activity goes awry, it is called a seizure. Some researchers think that synchronising the activity in different brain regions is important in perception.

Other ways of imaging brain activity are indirect. Functional magnetic resonance imaging (fMRI) or positron emission tomography (PET) monitor blood flow. MRI scans, computed tomography (CT) scans and diffusion tensor images (DTI) use the magnetic signatures of different tissues, X-ray absorption, or the movement of water molecules in those tissues, to image the brain.

These scanning techniques have revealed which parts of the brain are associated with which functions. Examples include activity related to sensations, movement, libido, choices, regrets, motivations and even racism. However, some experts argue that we put too much trust in these results and that they raise privacy issues.

Before scanning techniques were common, researchers relied on patients with brain damage caused by strokes, head injuries or illnesses, to determine which brain areas are required for certain functions. This approach exposed the regions connected to emotions, dreams, memory, language and perception and to even more enigmatic events, such as religious or “paranormal” experiences.

One famous example was the case of Phineas Gage, a 19th century railroad worker who lost part of the front of his brain when a 1-metre-long iron pole was blasted through his head during an explosion. He recovered physically, but was left with permanent changes to his personality, showing for the first time that specific brain regions are linked to different processes.

Structure in mind
The most obvious anatomical feature of our brains is the undulating surfac of the cerebrum – the deep clefts are known as sulci and its folds are gyri. The cerebrum is the largest part of our brain and is largely made up of the two cerebral hemispheres. It is the most evolutionarily recent brain structure, dealing with more complex cognitive brain activities.

It is often said that the right hemisphere is more creative and emotional and the left deals with logic, but the reality is more complex. Nonetheless, the sides do have some specialisations, with the left dealing with speech and language, the right with spatial and body awareness.

Further anatomical divisions of the cerebral hemispheres are the occipital lobe at the back, devoted to vision, and the parietal lobe above that, dealing with movement, position, orientation and calculation.

Behind the ears and temples lie the temporal lobes, dealing with sound and speech comprehension and some aspects of memory. And to the fore are the frontal and prefrontal lobes, often considered the most highly developed and most “human” of regions, dealing with the most complex thought, decision making, planning, conceptualising, attention control and working memory. They also deal with complex social emotions such as regret, morality and empathy.

Another way to classify the regions is as sensory cortex and motor cortex, controlling incoming information, and outgoing behaviour respectively.

Below the cerebral hemispheres, but still referred to as part of the forebrain, is the cingulate cortex, which deals with directing behaviour and pain. And beneath this lies the corpus callosum, which connects the two sides of the brain. Other important areas of the forebrain are the basal ganglia, responsible for movement, motivation and reward.

Urges and appetites
Beneath the forebrain lie more primitive brain regions. The limbic system, common to all mammals, deals with urges and appetites. Emotions are most closely linked with structures called the amygdala, caudate nucleus and putamen. Also in the limbic brain are the hippocampus – vital for forming new memories; the thalamus – a kind of sensory relay station; and the hypothalamus, which regulates bodily functions via hormone release from the pituitary gland.

The back of the brain has a highly convoluted and folded swelling called the cerebellum, which stores patterns of movement, habits and repeated tasks – things we can do without thinking about them.

The most primitive parts, the midbrain and brain stem, control the bodily functions we have no conscious control of, such as breathing, heart rate, blood pressure, sleep patterns, and so on. They also control signals that pass between the brain and the rest of the body, through the spinal cord.

Though we have discovered an enormous amount about the brain, huge and crucial mysteries remain. One of the most important is how does the brain produces our conscious experiences?

The vast majority of the brain’s activity is subconscious. But our conscious thoughts, sensations and perceptions – what define us as humans – cannot yet be explained in terms of brain activity.

After a discussion about study methods on one of the Afrikaans blogs, I’ve decided to add this info here as it relates to your brain too. This is a study method I taught 12 year old children. This is only one method of many others. A popular method is mind-maps too. All depends on the individual and the style he prefers.

P Q R S T

(I originally found this method in Atkinson, R. L., Atkinson, R. C., Smith, E. E., & Bem, D. J. (1993). Introduction to Psychology. Fort Worth, TX: Harcourt Brace, although that may not be the original source.)
PREVIEW
Skim the headings of the entire chapter. Your most important goal is to find out how the chapter is organized.
If the major terms in the headings are unfamiliar – look them up
The same material could be organized more than one way. If the way it is organized helps you to remember the main topics, then use that organization. If you notice some other way it could have been organized that makes more sense to you, then use that method.
QUESTION
Turn the subheadings under the major headings into questions that you expect to be answered in that part of the text.
READ
Try to see if the questions you anticipated are answered. Reflect on what you read; put it in your own words. Try to connect what you are reading to things you already know. Don’t mark or highlight words or passages as you come to them the first time. Wait until you have reached the end of a small section, maybe a paragraph or two and look back to decide if there is anything there that you probably wouldn’t remember without highlighting it. Try to learn through trial and error how much marking is the minimum you need to do to remember all the material.
SELF-RECITATION
This is the most critical part.
After reading a small section, perhaps a page or two CLOSE THE BOOK and try to write down the main ideas and as many details as you can, and then check yourself.
Put the main ideas and details in your own words; don’t just memorize the exact words in the text.
When you check, look for important things you omitted or got wrong.
Do it again. Do it as many times as you need to until you can close the book and reproduce the material accurately, but meaningfully, not just by rote.
Once you can do that immediately after closing the book, then start trying to do it after being away from the book for a while. First short gaps, like an hour, then longer gaps, like a day or two.
This is hard work. You might start by first trying to be able to make just a skeletal outline and build up the ability to fill in details.
Develop your own mnemonics for memorizing major points, or any details that you find confusing.
TEST
After some time has passed, try to reproduce the material as you did above. The key here is that you must give yourself enough time to forget some of the material so that you are forced to really re-generate the material. Re-generate means that you use your mnemonics and connections from the easier-to-remember main ideas to pull up the details.
Research has shown that reflection, spacing your study, and organizing all improve learning significantly.

What is alcohol? Alcohol is a clear drink that is made from corn, barley, grain, rye, or a beverage containing ethyl. When a person drinks alcohol, about 20 percent is absorbed in the stomach, and 80 percent is absorbed in the small intestine. The concentration of alcohol, the type of drink, and whether the stomach is full or empty depends on how fast the alcohol is absorbed. Once the alcohol is absorbed into the tissue, it affects your mind and body.  Blood alcohol concentration can rise up to 20 minutes after having a drink. After alcohol is absorbed it leaves the body in three ways: the kidneys, lungs, and liver.

How is it made?  Beer and  wine are called fermented beverages. They are made by adding yeast to a substance that contains sugar. The yeast starts the formation process, which turns sugar into ethyl and carbon dioxide gas. Beer is made from barley malt. The people who brew the beer soak the barley in water to make it sprout. When the barley dries, they take off the sprouts only leaving starch, or malt. The malt is ground up and mixed up with water to form mash. This is put into another mash which contains corn or rice that has been crushed and heated. The starch from corn or rice is then changed to sugar. Some dried flowers are added to the mash to add flavor, then the mash is fermented. Then the brewers age the beer for several weeks to add taste in the beer. http://library.thinkquest.org/TQ0310171/what_is_alcohol.htm

A drug used to treat seizures and migraines may help alcoholics quit the bottle, according to a study in the US. And unlike other medications for alcohol addiction, sufferers can get help without having to completely dry out first.
“You can be treated immediately for the disorder when you are in maximum crisis,” says the lead author
Bankole Johnson at the University of Virginia, Charlottesville, US.
Johnson and colleagues followed the progress of 317 individuals with alcohol dependence for 14 weeks. Half received treatment with the drug topiramate, an anti-convulsant sold under the brand name Topamax, while the other half received a placebo.
At the start of the study, participants were averaging about 11 drinks per day, and drinking heavily on more than 80% of their days. They totally abstained on approximately three days a month.
By the end of the study, those receiving the drug reported drinking heavily on just 20% of days. They also averaged only 3.5 drinks per day, and managed to stay completely sober more than half the time.

Pleasure blocking
The control group also improved, but significantly less. They drank heavily on more than 40% of days, consumed six drinks per day, and abstained from drinking about a third of the time.

Topiramate works by blocking the release of the neurotransmitter dopamine, which reinforces the pleasurable feelings that alcoholics get when they drink.

In an accompanying editorial, Mark Willenbring at the US National Institute on Alcohol Abuse and Alcoholism says the primary problem now is how to improve patient access to treatments like topiramate, since alcohol abuse remains a woefully under-treated disorder.

“One potential solution is for primary care physicians and psychiatrists to begin systematically identifying and treating alcohol dependence in their patients,” he says.

Topiramate, which is not currently approved by the FDA for alcohol abuse, is already being used “off label” for this disorder, according to Johnson. “My hope is that topiramate continues to be validated and tested by other doctors, and if they want to [prescribe it off-label], they should.”

WHAT IS ALCOHOL?
What Is Alcohol?
Alcohol is created when grains, fruits, or vegetables are fermented. Fermentation is a process that uses yeast or bacteria to change the sugars in the food into alcohol. Fermentation is used to produce many necessary items — everything from cheese to medications. Alcohol has different forms and can be used as a cleaner, an antiseptic, or a sedative.

So if alcohol is a natural product, why do teens need to be concerned about drinking it? When people drink alcohol, it’s absorbed into their bloodstream. From there, it affects the central nervous system (the brain and spinal cord), which controls virtually all body functions. Because experts now know that the human brain is still developing during our teens, scientists are researching the effects drinking alcohol can have on the teen brain.

How Does It Affect the Body?

Alcohol is a depressant, which means it slows the function of the central nervous system. Alcohol actually blocks some of the messages trying to get to the brain. This alters a person’s perceptions, emotions, movement, vision, and hearing.

In very small amounts, alcohol can help a person feel more relaxed or less anxious. More alcohol causes greater changes in the brain, resulting in intoxication. People who have overused alcohol may stagger, lose their coordination, and slur their speech. They will probably be confused and disoriented. Depending on the person, intoxication can make someone very friendly and talkative or very aggressive and angry. Reaction times are slowed dramatically — which is why people are told not to drink and drive. People who are intoxicated may think they’re moving properly when they’re not. They may act totally out of character.

When large amounts of alcohol are consumed in a short period of time, alcohol poisoning can result. Alcohol poisoning is exactly what it sounds like — the body has become poisoned by large amounts of alcohol. Violent vomiting is usually the first symptom of alcohol poisoning. Extreme sleepiness, unconsciousness, difficulty breathing, dangerously low blood sugar, seizures, and even death may result.

Why Do Teens Drink?

Experimentation with alcohol during the teen years is common. Some reasons that teens use alcohol and other drugs are:

  • curiosity
  • to feel good, reduce stress, and relax
  • to fit in
  • to feel older

From a very young age, kids see advertising messages showing beautiful people enjoying life — and alcohol. And because many parents and other adults use alcohol socially — having beer or wine with dinner, for example — alcohol seems harmless to many teens.

Why Shouldn’t I Drink?

Although it’s illegal to buy alcohol in the United States until the age of 21, most teens can get access to it. It’s therefore up to you to make a decision about drinking. In addition to the possibility of becoming addicted, there are some downsides to drinking:

The punishment is severe. Teens who drink put themselves at risk for obvious problems with the law (it’s illegal; you can get arrested). Teens who drink are also more likely to get into fights and commit crimes than those who don’t.

People who drink regularly also often have problems with school. Drinking can damage a student’s ability to study well and get decent grades, as well as affect sports performance (the coordination thing).

You can look really stupid. The impression is that drinking is cool, but the nervous system changes that come from drinking alcohol can make people do stupid or embarrassing things, like throwing up or peeing on themselves. Drinking also gives people bad breath, and no one enjoys a hangover.

Alcohol puts your health at risk. Teens who drink are more likely to be sexually active and to have unsafe, unprotected sex. Resulting pregnancies and sexually transmitted diseases can change — or even end — lives. The risk of injuring yourself, maybe even fatally, is higher when you’re under the influence, too. One half of all drowning deaths among teen guys are related to alcohol use. Use of alcohol greatly increases the chance that a teen will be involved in a car crash, homicide, or suicide.

Teen drinkers are more likely to get fat or have health problems, too. One study by the University of Washington found that people who regularly had five or more drinks in a row starting at age 13 were much more likely to be overweight or have high blood pressure by age 24 than their nondrinking peers. People who continue drinking heavily well into adulthood risk damaging their organs, such as the liver, heart, and brain.

How Can I Avoid Drinking?

If all your friends drink and you don’t want to, it can be hard to say “no, thanks.” No one wants to risk feeling rejected or left out. Different strategies for turning down alcohol work for different people. Some people find it helps to say no without giving an explanation, others think offering their reasons works better (“I’m not into drinking,” “I have a game tomorrow,” or “my uncle died from drinking,” for example).

If saying no to alcohol makes you feel uncomfortable in front of people you know, blame your parents or another adult for your refusal. Saying, “My parents are coming to pick me up soon,” “I already got in major trouble for drinking once, I can’t do it again,” or “my coach would kill me,” can make saying no a bit easier for some.

If you’re going to a party and you know there will be alcohol, plan your strategy in advance. You and a friend can develop a signal for when it’s time to leave, for example. You can also make sure that you have plans to do something besides just hanging out in someone’s basement drinking beer all night. Plan a trip to the movies, the mall, a concert, or a sports event. You might also organize your friends into a volleyball, bowling, or softball team — any activity that gets you moving.

Girls or guys who have strong self-esteem are less likely to become problem drinkers than people with low self-esteem.

Where Can I Get Help?

If you think you have a drinking problem, get help as soon as possible. The best approach is to talk to an adult you trust. If you can’t approach your parents, talk to your doctor, school counselor, clergy member, aunt, or uncle. It can be hard for some people to talk to adults about these issues, but a supportive person in a position to help can refer students to a drug and alcohol counselor for evaluation and treatment.

In some states, this treatment is completely confidential. After assessing a teen’s problem, a counselor may recommend a brief stay in rehab or outpatient treatment. These treatment centers help a person gradually overcome the physical and psychological dependence on alcohol.

What If I’m Concerned About Someone Else’s Drinking?

Many people live in homes where a parent or other family member drinks too much. This may make you angry, scared, and depressed. Many people can’t control their drinking without help. This doesn’t mean that they love or care about you any less. Alcoholism is an illness that needs to be treated just like other illnesses.

People with drinking problems can’t stop drinking until they are ready to admit they have a problem and get help. This can leave family members and loved ones feeling helpless. The good news is there are many places to turn for help: a supportive adult, such as your guidance counselor, or a relative or older sibling will understand what you’re going through. Also, professional organizations like Alateen can help.

If you have a friend whose drinking concerns you, make sure he or she stays safe. Don’t let your friend drink and drive, for example. If you can, try to keep friends who have been drinking from doing anything dangerous, such as trying to walk home at night alone or starting a fight. And protect yourself, too. Don’t get in a car with someone who’s been drinking, even if that person is your ride home. Ask a sober adult to drive you instead or call a cab.

Everyone makes decisions about whether to drink and how much — even adults. It’s possible to enjoy a party or other event just as much, if not more so, when you don’t drink. And with your central nervous system working as it’s supposed to, you’ll remember more about the great time you had!

Alcohol….MORE…
What are its short-term effects?
When a person drinks alcohol, the alcohol is absorbed by the stomach, enters the bloodstream, and goes to all the tissues. The effects of alcohol are dependent on a variety of factors, including a person’s size, weight, age, and sex, as well as the amount of food and alcohol consumed. The disinhibiting effect of alcohol is one of the main reasons it is used in so many social situations. Other effects of moderate alcohol intake include dizziness and talkativeness; the immediate effects of a larger amount of alcohol include slurred speech, disturbed sleep, nausea, and vomiting. Alcohol, even at low doses, significantly impairs the judgment and coordination required to drive a car safely. Low to moderate doses of alcohol can also increase the incidence of a variety of aggressive acts, including domestic violence and child abuse. Hangovers are another possible effect after large amounts of alcohol are consumed; a hangover consists of headache, nausea, thirst, dizziness, and fatigue.
What are its long-term effects?
Prolonged, heavy use of alcohol can lead to addiction (alcoholism). Sudden cessation of long term, extensive alcohol intake is likely to produce withdrawal symptoms, including severe anxiety, tremors, hallucinations and convulsions. Long-term effects of consuming large quantities of alcohol, especially when combined with poor nutrition, can lead to permanent damage to vital organs such as the brain and liver. In addition, mothers who drink alcohol during pregnancy may give birth to infants with fetal alcohol syndrome. These infants may suffer from mental retardation and other irreversible physical abnormalities. In addition, research indicates that children of alcoholic parents are at greater risk than other children of becoming alcoholics

In 1997, Americans drank an average of 2 gallons (7.57 liters) of alcohol per person. This translates roughly into one six-pack of beer, two glasses of wine and three or four mixed drinks per week (see MMWR: Apparent Per Capita Ethanol Consumption for details). About 35 percent of adults don’t consume alcohol, so the numbers are actually higher for those who do — alcohol is an amazingly popular social phenomenon.

If you have ever seen a person who has had too much to drink, you know that alcohol is a drug that has widespread effects on the body, and the effects vary from person to person. People who drink might be the “life of the party” or they might become s­ad and droopy. Their speech may slur and they may have trouble walking. It all depends on the amount of alcohol consumed, a person’s history with alcohol and a person’s personality.

Even though you have seen the physical and behavioral changes, you might wonder exactly how alcohol works on the body to produce those effects. What is alcohol? How does the body process it? How does the chemistry of alcohol work on the chemistry of the brain? In this article, we will examine all of the ways in which alcohol affects the human body.

Definition
Alcoholism is an illness marked by drinking alcoholic beverages at a level that interferes with physical health, mental health, and social, family, or occupational responsibilities.

Alcoholism is divided into 2 categories: dependence and abuse.

People with alcohol dependence, the most severe alcohol disorder, usually experience tolerance and withdrawal. Tolerance is a need for markedly increased amounts of alcohol to achieve intoxication or the desired effect. Withdrawal occurs when alcohol is discontinued or intake is decreased. Alcohol dependents spend a great deal of time drinking alcohol, and obtaining it.

Alcohol abusers may have legal problems such as drinking and driving. They may also have problems with binge drinking (drinking 6 or more drinks at one sitting).

People who are dependent on or abuse alcohol continue to drink it despite evidence of physical or psychological problems. Those with dependence have more severe problems and a greater compulsion to drink
