How nerve cells within the brain communicate with each other over long distances has puzzled scientists for decades. The way networks of neurons connect and how individual cells react to incoming pulses in principle makes communication over large distances impossible.

Discovery may help treat memory disorders resulting from stroke, Alzheimer's and brain injury Stimulating a particular region in the brain via non-invasive delivery of electrical current using magnetic pulses, called Transcranial Magnetic Stimulation, improves memory, reports a new Northwestern Medicine® study.

A new method for measuring and imaging how quickly blood flows in the brain could help doctors and researchers better understand how drug abuse affects the brain, which may aid in improving brain-cancer surgery and tissue engineering, and lead to better treatment options for recovering drug addicts.

Brain's motor areas can directly turn down hearing When we want to listen carefully to someone, the first thing we do is stop talking. The second thing we do is stop moving altogether. This strategy helps us hear better by preventing unwanted sounds generated by our own movements.

A new study in Biological Psychiatry maps the circuitry of dyslexia Dyslexia, the most commonly diagnosed learning disability in the United States, is a neurological reading disability that occurs when the regions of the brain that process written language don't function normally.

Researchers discover new treatment approach for this hereditary neurological disorder Charcot-Marie-Tooth disease type 1A is the most common inherited disease affecting the peripheral nervous system.

New evidence puts into doubt the long-standing belief that a deficiency in serotonin — a chemical messenger in the brain — plays a central role in depression. In the journal ACS Chemical Neuroscience, scientists report that mice lacking the ability to make serotonin in their brains (and thus should have been “depressed” by conventional wisdom) did not show depression-like symptoms.

Weight loss surgery can curb alterations in brain activity associated with obesity and improve cognitive function involved in planning, strategizing and organizing, according to a new study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

Scientists at the University of Warwick have provided the first evidence that the lack of a naturally occurring protein is linked to early signs of dementia.

Older patients with Parkinson disease (PD) who undergo deep brain stimulation (DBS) appear to have a 90-day complication risk similar to younger patients, suggesting that age alone should not be a primary factor for excluding patients as DBS candidates.
