Epilepsy and brain pathology linked together by the protein ADK
The brain of individuals who suffer from epilepsy is characterized by astrogliosis, a brain pathology evidenced by a complex series of changes in the morphology and function of brain cells known as astrocytes. view more (2008-01-03)
Mechanism Behind Stuttering Revealed (p 380)
Stuttering is caused by a structural abnormality in the left hemisphere of the brain, according to an article in this week's LANCET. Dr Martin Sommer and colleagues from the Universities of Hamburg and Göttingen in Germany report that persistent developmental stuttering results from a disconnection of speech-related areas in the cortex.... view more...

Research leads to healthful strategies for re-setting the body's clock
Everyone is equipped with a biological clock, a region in the brain the size of a corn kernel, which dictates our sleep-wake cycles, and plays a major role in our physical and mental health. view more (2006-03-23)
Leptin has powerful effect on reward center in the brain
Leptin, a hormone critical for normal food intake and metabolism, exerts a strong effect on appetite by acting in the mid-brain region as well as in the hypothalamus. view more (2006-09-29)
Reorganization of brain area for vision after stroke: May yield new treatments for brain injury
New evidence from a patient shows that the area of the brain that processes visual inputs can reorganize after an injury caused by stroke. view more (2007-09-05)
Children's National 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. view more (2009-01-13)
Memory mission explores new territory in neuroscience
Astrophysicists peer into the far corners of deep space for dark matter, but for neuroscientists at the Queensland Brain Institute (QBI) exploring the unknown is much closer to home. view more (2008-11-21)
Parts of brain involved in social cognition may be in place by age 6
Social cognition-the ability to think about the minds and mental states of others-is essential for human beings. In the last decade, a group of regions has been discovered in the human brain that are specifically used for social cognition. view more (2009-07-15)
Brain center for 'sound space' identified
While the visual regions of the brain have been intensively mapped, many important regions for auditory processing remain terra incognita. Now, researchers have identified the region responsible for a key auditory process-perceiving "sound space," the location of sounds. view more (2007-09-20)
Sound adds speed to visual perception
The traditional view of individual brain areas involved in perception of different sensory stimuli-i.e., one brain region involved in hearing and another involved in seeing-has been thrown into doubt in recent years. view more (2008-08-12)
Pitt research identifies new target in brain for treating schizophrenia
Research from the University of Pittsburgh could expand the options for controlling schizophrenia by identifying a brain region that responds to more than one type of antipsychotic drug. view more (2008-11-06)
Risk and reward compete in brain
That familiar pull between the promise of victory and the dread of defeat - whether in money, love or sport - is rooted in the brain's architecture, according to a new imaging study. view more (2008-10-10)
Gene linked with mental illness shapes brain region, researchers find
A gene variant associated with mental illness goes hand-in-hand with enlargement of a brain region that handles negative emotions, researchers at UT Southwestern Medical Center and the Central Texas Veterans Health Care System have found. view more (2006-11-08)
Brain region central to placebo effect identified
Researchers have pinpointed a brain region central to the machinery of the placebo effect-the often controversial phenomenon in which a person's belief in the efficacy of a treatment such as a painkilling drug influences its effect. view more (2007-07-19)
When your memories can no longer be trusted
You went to a wedding yesterday. The service was beautiful, the food and drink flowed and there was dancing all night. But people tell you that you are in hospital, that you have been in hospital for weeks, and that you didn't go to a wedding yesterday at all. view more (2008-05-29)
More than just pretty faces for this brain region, says Stanford researcher
You'll find more than faces in these places. Stanford University researchers have taken the closest look yet at a region of the brain that was thought to be devoted solely to face recognition and discovered that this particular patchwork of neurons does much more: It also responds to such objects as cars, animals and sculptures. view more (2006-08-30)
Impulse control area in brain affected in teens with genetic vulnerability for alcoholism
A new study suggests that genetic factors influence size variations in a certain region of the brain, which could in turn be partly responsible for increased susceptibility to alcohol dependence. view more (2008-11-07)
Dying of excitement
For neurons, overexcitement is deadly. To avoid this, brain cells must sop up unneeded neurotransmitters from the synapse through membrane-bound transporters. If these transporters fail, neurons and other brain cells get excited to death- a phenomenon that may contribute to brain damage during stroke and Alzheimer's disease. view more (2006-03-06)
Does stress damage the brain?
Individuals who experience military combat obviously endure extreme stress, and this exposure leaves many diagnosed with the psychiatric condition of post-traumatic stress disorder, or PTSD. PTSD is associated with several abnormalities in brain structure and function. view more (2008-03-19)
Researchers identify brain's 'eureka' circuitry
Researchers have found the brain region that controls the decision to halt your midnight exploration of the refrigerator and commence enjoyment of that leftover chicken leg. What's more, they said, such mechanisms governing exploration are among those that malfunction in addiction and mental illness. view more (2008-01-24)
