The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Single memory is processed in three separate parts of the brain - important for search to understand memory disorders

UCI researchers have found that a single brief memory is actually processed differently in separate areas of the brain - an idea that until now scientists have only suspected to be true.

Depression linked to Alzheimer's

A lifetime history of depression is associated with increased plaques and tangles in the brains of those with Alzheimer's disease and more rapid cognitive decline, according to a study by researchers at the Alzheimer's Disease Research Center at Mount Sinai School of Medicine.

Case biologists move closer to biologically inspired robots

The brain as command center for bodily movement was too simple an idea, thought the Russian physiologist Nicolas Bernstein some 60 years ago.

Women more sensitive to pain during periods of low estrogen

Now researchers are going one step further by studying whether the difference in pain sensitivity is reflected in brain activity as measured by functional magnetic resonance imaging (fMRI).

Hormone discovered in bird brains also plays major role in mammalian reproductive system

University of California, Berkeley, researchers have discovered a new actor in the mammalian reproductive system, a hormone that fills a role long suspected, but until now undetected.

Mad cow proteins also maintain stem cells

What do mad cow disease and stem cell research have in common? Whitehead Institute scientists have found that the same protein that causes neurodegenerative conditions such as bovine spongiform encephalopathy (mad cow disease) is also important for helping certain adult stem cells maintain themselves.

Can marriages be saved by treating snoring?

The husband snores. The wife nudges him to flip over. Both wake up feeling grouchy the next morning. It's a common occurrence that may have more of an impact on the marriage than most couples think.

Pain sensitivity is enhanced when people are thirsty

Researchers at Melbourne's Howard Florey Institute have discovered how the brain prioritises pain and thirst in order to survive - a mechanism that helps elite athletes to 'push through the pain barrier'.

Link between dementia and cancer

By expressing a protein associated with Alzheimer's disease in the brain of the fruit fly, researchers have demonstrated an intriguing link between neuronal death and proteins previously associated with cancer.

Abraham Lincoln may have suffered from movement disorder

Researchers at Johns Hopkins and the University of Minnesota have discovered a gene mutation in the descendants of Abraham Lincoln's grandparents that suggests the Civil War president himself might have also suffered from a disease that destroys nerve cells in the cerebellum-- the part of the brain that controls movement.

Mechanism of torpor - hibernation-like state

If doctors could put people in hibernation and pull them out at will, scientists think they could minimize damage from strokes, help recipients' bodies accept transplanted organs, perhaps even enable astronauts to travel in suspended animation until reaching distant destinations.

Imaging technology detects subtle brain changes in Type 1 diabetics

Although people with diabetes are twice as likely as the general population to develop depression, the cause of this increased risk is not well understood.

38 million Americans with health conditions that put them at increased risk for cardiovascular disease

An estimated 63 million adults have low-density lipoprotein cholesterol (LDL-C) levels higher than what would be ideal as recommended by the National Institutes of Health.

Researchers gain new insights into when human maturity sets in

Two Dartmouth researchers are one step closer to defining exactly when human maturity sets in. In a study aimed at identifying how and when a person's brain reaches adulthood, the scientists have learned that, anatomically, significant changes in brain structure continue after age 18.

Ability for grammar hardwired into humans

Researchers have long wondered why certain fundamental characteristics of grammar are present in all languages, and now a team of scientists at the University of Rochester has found evidence that these properties are built into the way our brains work.

Study finds brain changes begin gradually in 'middle age'

A study looking at brain function in young, middle-aged and older adults has identified changes in brain activity that begin gradually in middle age - and which may explain why older adults find it difficult to concentrate in busy environments and filter out irrelevant information.

Researchers discover lowered sensitivity to smell when lying down

Before giving flowers or scattering rose petals on Valentine's Day, make sure your significant other has already gotten out of bed. In a study published recently in the journal Chemical Senses, researchers at the Montreal Neurological Institute (MNI) at McGill University discovered that sensitivity to rose odour is greater in subjects that are sitting than in those lying down.
