How the Human Brain Really Works

human brain

Two top neuro-scientists, Sandra Aamodt and Sam Wang, have written an engaging book titled Welcome to Your Brain (Bloomsbury USA, 2008). The book explains new discoveries in brain research, offers tips for enhancing brain health, and debunks many long-held myths about the brain. A few of these myths are:

We Only Use 10% of Our Brain Capacity

Not so, say Aamodt and Wang. Most of us use nearly 100% of our brains every day. The authors explain that nature doesn’t support structures that will never be used, so while the brain does have back up systems in the event of damage to critical areas, most of the brain is needed and used in day-to-day living.

Mozart Makes Babies Smarter

A small 1993 research project gave birth to the Mozart myth. The study showed that college students who listened to classical music prior to taking the SAT test scored a little better than their peers. The study has never been successfully replicated, and no one has ever published a report on the relationship between listening to classical music and smarter children. Nevertheless, the myth persists and products based on this unfounded assertion have sold millions. Aamodt and Wang say the best way to increase a child’s mental ability is to buy them an instrument and teach them to play classical music.

Alcohol Kills Brain Cells

It is widely accepted that any amount of alcohol kills brain cells. While it is true that chronic heavy drinking over a period of years is associated with many physical and neurological problems, including dementia, several studies conclude that moderate drinking produces no such damage. In fact, research suggests that drinking red wine actually reduces the risk of dementia and stroke. Aamodt and Wang cite several studies that conclude men can safely imbibe up to three drinks a day, and women up to two a day, with no adverse effects on the brain.

Reduce Risk of Alzheimer's with Exercise

Crossword puzzles and other mental challenges are good, but Aamodt and Wang assert that the best thing anyone can do for his brain is to exercise. Thirty minutes of strenuous exercise, such as fast walking, several times a week significantly reduces the risk of Alzheimer’s and other forms of dementia. People who have been physically active throughout their lives enjoy the greatest protection, but it is never too late to start. Aamodt and Wang report that sedentary people who begin exercising in their sixties can still reduce their risk of Alzheimer’s by up to one half.

Read Welcome to Your Brain
Much of what the public believes about the brain is false, and much of what neuro-scientists have discovered about the brain is unknown to all but a few researchers. Welcome to Your Brain by Sandra Aamodt and Sam Wang corrects this situation with humor, good writing, and fascinating science.

Nutrients for Cleansing the Heart and Arteries

There are a series of nutrients that decrease cholesterol and saturated fat in the blood and arteries. These are lecithin, vitamin E and vitamin C , and niacin . These nutrients function efficiently in cleaning the arteries when taken in whole food. Lecithin is found in most legumes , particularly in soybeans. Both soybeans and mung beans are recommended by numerous researches and mainly by Chinese medicine for cleansing arteries, although nearly all beans, peas, and lentils are helpful. This is partly because legumes are a good source of choline, a lipotrophic agent that controls fat metabolism ; choline is also a main component of lecithin. When heat symptoms occur with arterial problems , the cooling qualities of soy and mung bean sprouts are useful. These sprouts are usually found in grocery stores and markets with well-stocked produce. Sprouts are also an excellent source of vitamin C, as well as cabbage, parsley, bell peppers, and citrus.

Causes of Easy Bruising: Reasons Why People Bruise Easily

Bruising , a reddish or purple discoloration under the skin, most often results from trauma to the small blood vessels, called capillaries, but can also occur spontaneously. How and Why Bruises Occur Blood leaks out of the capillaries and accumulates under the skin, gradually absorbing over several days. Bruising most often occurs because people run into objects or experience other trauma. Most bruising is easily explained, but frequent bruising that occurs without obvious cause needs prompt investigation, since several serious diseases can cause bruising. In general, women bruise more easily than men. How Aging Increases the Risk of Easy Bruising Bruising increases as people age for several reasons. Skin thins as people age and the capillaries become more fragile. The layer of fat that cushions blood vessels and protects them from injury becomes thinner as well. Older people often take medications and supplements that thin the blood and contribute to easy bruising. Visi

Stye - Symptoms and Treatment

A stye is an infection, typically a bacterial infection, which causes a painful red lump either on the edge or inside of the eyelid. Bacteria grow at the root of an eyelash follicle or inside an oil gland. The bacteria can be a result of poor hygiene, touching the eyes with unwashed hands or chronic inflammation. The stye resembles a pimple or a boil and is usually filled with pus. A stye does not pose a risk to vision and most often heals without treatment within a week. However, a stye may require treatment with a doctor if the infection does not resolve with at-home remedies. Symptoms of a Stye A stye is not usually hard to spot. Not only does a red lump form on either the top or bottom eyelid, but pain is also an immediate symptom of the condition. Typical symptoms of a stye include: red lump on the eyelid similar to a pimple watering of the eye eyelid pain and swelling clear or yellow fluid collecting in the stye A normal stye will come to a head in approximately three to
