Brain & Nervous System
Multiple sclerosis leads to degeneration of axons, the long fibers that carry electrical impulses from nerve cell to nerve cell.
Understanding where noise arises in the brain has implications for advancing research in neuromotor control and in developing therapies for disorders where control is impaired, such as Parkinson's disease.
A version of a gene previously linked to impulsive violence appears to weaken brain circuits that regulate impulses, emotional memory and thinking in humans.
The technique involves surgically replacing damaged axons, the long, fragile fibers that conduct impulses between nerve cells in the brain, spinal cord and limbs, with healthy ones.
The findings could help improve: communication between physicians and patients, patient attitudes toward various conditions, newspaper coverage of neurologic conditions, and general health care coverage.
This finding may lead to a greater understanding of disorders such as multiple sclerosis that affect myelin, as well as a greater understanding of the learning process.
Certain behaviors are so crucial to survival that the brains of all vertebrates contain clusters of nerve cells that can suppress pain long enough to allow the animal to eat, drink or pee.
Researchers from the University of Chicago have uncovered an important mechanism used by the developing brain to pattern nerve connections in the part of the brain that interprets visual signals.
The first known case of a new memory syndrome: a woman with the ability to perfectly and instantly recall details of her past.
Symptoms of Huntington's Disease, which usually begin to appear in the middle years, include uncontrolled movement, erratic emotions and problems with thinking and memory.
New brain cells that develop in the olfactory system of adult mice appear to play a role in the brain different from that of older neurons.
The relationship between the size of a brain structure and the ability to recover from traumatic experiences also may influence overall personality type.
A toxic chemical called sarin inflicts widespread damage to genes that control memory, thinking, mood, muscle control and a range of other brain functions.
Researchers at Johns Hopkins have discovered how to block a molecular switch that triggers brain damage caused by the lack of oxygen during a stroke.
The potential existence of human brain stem cells could have an enormous impact in understanding and subsequently developing treatments for brain diseases.
Although it has been possible to open narrowed brain vessels prior to Wingspan by using stents made of stainless steel, this new device is specifically for use in the brain.
Researchers have identified a master protein that sheds light on one of neurobiology's biggest mysteries: how neurons change as a result of individual experiences.
Sex chromosome genes may not be the whole story that determines how aggressive or motherly we are, but they are a part of it.
Two conditions in the brain, high amounts of white matter and enlarged open areas called ventricles, are associated with cardiovascular disease and shorter lives in the elderly.
Distinct regions of the human brain are activated when people are faced with ambiguous choices versus choices involving only risk.
Modern neuroimaging research has produced the possibility of monitoring thought in ways you couldn't before.
A diuretic drug called bumetanide may serendipitously help treat seizures in newborns, which are difficult to control with existing anticonvulsants.
When neurons were exposed to a growth factor known as brain derived neurotrophic factor (BDNF), this inhibition was overcome and Limk1 became active again, enhancing spine growth.
Findings could lead to new treatments for epileptic seizures and chronic fatigue.
