Parkinson's disease is a disorder of the brain that leads to shaking, difficulty with walking, movement, and coordination. With 50,000 new cases reported every year it is one of the most common nervous system disorders of the elderly. Researchers are attempting to develop stem cell therapy to replace cells causing this disease.
A genetically-modified version of the rabies virus is helping scientists at Harvard to trace neural pathways in the brain, a research effort that could one day lead to treatments for Parkinson's disease and addiction.
What characterizes many people with depression, schizophrenia and some other mental illnesses is anhedonia: an inability to gain pleasure from normally pleasurable experiences.
Harvard scientists have developed the fullest picture yet of how neurons in the brain interact to reinforce behaviors ranging from learning to drug use, a finding that might open the door to possible breakthroughs in the treatment of addiction.
A brain cell type found where habits are formed and movement is controlled has receptors that work like computer processors to translate regular activities into habits.
When healthy people are faced with threatening situations, they react with a suitable behavioral response and do not descend into a state of either panic or indifference, as is the case, for example, with patients who suffer from anxiety.
Removing a protein from cells located in the brain's reward center blocks the anxiety-reducing and rewarding effects of nicotine.
New research from the University of Chicago Medical Center has given new insight into just what makes cocaine and nicotine so addictive.
The effects of nicotine upon brain regions involved in addiction mirror those of cocaine, according to new neuroscience research.
A team of neuroscientists at Cold Spring Harbor Laboratory (CSHL), Brookhaven National Laboratory (BNL) and UC San Diego (UCSD) has collected evidence suggesting that a previously overlooked portion of the brain could be a prime locus of human depression.
