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.

Near-infrared light used to detect signs of Alzheimer's disease

A team of researchers in Bedford, Mass. has developed a way of examining brain tissue with near-infrared light to detect signs of Alzheimer's disease.

Researchers discover second depth-perception method in brain

It's common knowledge that humans and other animals are able to visually judge depth because we have two eyes and the brain compares the images from each.

Pain receptor in brain may be linked to learning and memory

Scientists have long known that the nervous system receptor known as TRPV1 can affect sensations of pain in the body.

New drug protects nerve cells from damage in mice

Multiple sclerosis (MS) is a chronic inflammatory disease of the brain and spinal cord. Individuals with MS develop progressive neurological disability, and this is thought to be caused by degradation of the nerve cells.

Study shows Parkinson's disease drug dopamine might work in cancer patients

A study published in the March 13 online issue of The Journal of Clinical Investigation shows that dopamine, a drug currently used to treat Parkinson's disease and other illnesses, also might work in cancer patients.

The yin and yang of genes for mood disorders

Individual genes do not cause depression, but they are thought to increase the probability of an individual having a depression in the face of other accumulating risk factors, such as other genes and environmental stressors.

TRPV1 receptor blockers may interfere with brain functions

A new class of painkillers that block a receptor called TRPV1 may interfere with brain functions such as learning and memory, a new study suggests.

Increased level of magnetic iron oxides found in Alzheimer's disease

A team of scientists, led by Professor Jon Dobson, of Keele University in Staffordshire, UK, have found, for the first time, raised levels of magnetic iron oxides in the part of the brain affected by Alzheimer's Disease (AD).

Study shows how nerve cells in visual cortex adapt to changing images

Neuroscientists studying the mind's ability to process images have completed the first empirical study to demonstrate, using animal models, how populations of nerve cells in visual cortex adapt to changing images.

Researchers model emotional impact of cocaine in rats

Cocaine addicts often suffer a downward emotional spiral that is a key to their craving and chronic relapse.

Different use of brain areas may explain memory problems in schizophrenics

The enduring memory problems that people with schizophrenia experience may be related to differences in how their brains process information, new research has found.

Bird brains suggest how vocal learning evolved

Though they perch far apart on the avian family tree, birds with the ability to learn songs use similar brain structures to sing their tunes.

New mouse model of bipolar disorder

Bipolar Disorder (BPD or manic-depressive illness) is one of the most serious of all mental disorders, affecting millions of individuals worldwide.

Researchers may have found test for depression

Researchers from the University of Illinois at Chicago College of Medicine have discovered that a change in the location of a protein in the brain could serve as a biomarker for depression, allowing a simple, rapid, laboratory test to identify patients with depression and to determine whether a particular antidepressant therapy will provide a successful response.

Short-term stress impairs brain-cell communication

Short-term stress lasting as little as a few hours can impair brain-cell communication in areas associated with learning and memory, University of California, Irvine researchers have found.

Post brain injury: New nerve cells originate from neural stem cells

Most cells in the human brain are not nerve cells, but supporting cells (glial cells).

Switch for programmed cell death promotes spread of glioblastoma

Malignant tumors have usually lost their ability to destroy themselves by programmed cell death, or apoptosis.

New resuscitation approach for out-of-hospital cardiac arrest associated with increased survival

Patients who had cardiac arrests outside of the hospital setting and were treated with a resuscitation approach designed to limit interruption of chest compressions, termed minimally interrupted cardiac resuscitation (MICR), were more likely to survive than those patients who received standard treatments, according to a study in the March 12 issue of JAMA.
