New insights into growth factor's role in brain development

New research sheds light on a neural growth factor called proBDNF, finding that it is present and potentially active during the perinatal period when the brain's circuitry and memory-encoding regions are being refined.

Sociability traced to region of brain called amygdala

People with a genetic condition called Williams syndrome are famously gregarious. Scientists, looking carefully at brain function in individuals with Williams syndrome, think they may know why this is so.

Researchers discover link between brain iron levels and serotonin

Vanderbilt University Medical Center investigators have found a surprising link between brain iron levels and serotonin, a neurotransmitter involved in neuropsychiatric conditions ranging from autism to major depression.

Imaging study shows how memories become permanent

A new brain imaging study illustrates what happens to memories as time goes by.

Discovery of brain's memory 'buffer' in single cells

Individual nerve cells in the front part of the brain can hold traces of memories on their own for as long as a minute and possibly longer, researchers at UT Southwestern Medical Center have found.

Early treatment with rasagiline (Azilect) for Parkinson's best

There is hope that the drug rasagiline can do what no other medication for Parkinson's disease now does -- slow the progression of a devastating degenerative brain disease that eventually robs people of their ability to move and function.

When less attention improves behavior

A new study conducted at the Centre for Studies and Research in Cognitive Neuroscience of the University of Bologna, and published by Elsevier in the February 2009 issue of Cortex shows that, in confabulating patients, memory accuracy improves when attentional resources are reduced.

More scientific evidence supporting Darwinian views of evolution

Studies at the University of Pennsylvania School of Medicine on brain electrical signaling offer a fresh perspective on vertebrate evolution, provide additional evidence supporting Darwinian views of evolution, and may also lead to more effective treatment of epileptic seizures in infants.

Dynamical theory and novel 4-D colorimetric method reveal modus operandi of intact living brain

For the brain to achieve its intricate functions such as perception, action, attention and decision making, neural regions have to work together yet still retain their specialized roles.

Altered brain activity in schizophrenia may direct focus on self

Schizophrenia may blur the boundary between internal and external realities by overactivating a brain system that is involved in self-reflection, and thus causing an exaggerated focus on self, a new MIT and Harvard brain imaging study has found.

Odors can alter gene expression in an olfactory neuron

New research from University of California, Davis, shows why a species of tiny worm can learn to ignore an odor – information that could have implications for how human memories are formed.

Repressive protein plays unexpected role in odor adaptation

New research provides valuable insight into the molecular mechanisms that allow experience to influence behavior.

Scientists uncover key developmental mechanisms of the amygdala

For the first time, scientists at Children's National Medical Center have successfully identified a key developmental program for the amygdala-the part of the limbic system that impacts how the brain creates emotional memories and responses.

Discovery of first gender-linked susceptibility gene for late-onset Alzheimer's disease

In the Jan. 11 online edition of Nature Genetics, they report the results of their two-stage genome-wide association study of patients with Alzheimer's disease. The research showed that women who inherited two copies of a variant in the PCDH11X gene, found on the X chromosome, are at considerably greater risk of developing Alzheimer's disease.
