Losing sleep undoes the rejuvenating effects new learning has on the brain
Sleep deprivation impairs spatial learning - including remembering how to get to a new destination. And now scientists are beginning to understand how that happens view more (2006-01-09)
New Research Shows Why Too Much Memory May Be a Bad Thing
New research from Columbia University Medical Center may explain why people who are able to easily and accurately recall historical dates or long-ago events, may have a harder time with word recall or remembering the day's current events. They may have too much memory - making it harder to filter out information and increasing the time it takes... view more... (2007-03-30)
Brain memory area modifies its wiring diagram during the female cycle
Researchers at Northwestern University and Columbia University have found that "wiring" in female rat brain memory area expands and retracts in relation to the amount of estrogen present during the estrous/menstrual cycle. view more (2005-11-15)
Good news for the medical marijuana movement: pot proliferates brain cells and boosts mood
Most drugs of abuse decrease the generation of new neurons in the brain, but the effects of marijuana on this process, called neurogenesis, had not been clear. view more (2005-10-14)
Mad cow protein aids creation of brain cells
Few conditions are more detrimental to human brains than the one popularly referred to as mad cow disease. view more (2006-02-14)
Healing potential discovered in everyday human brain cells
University of Florida researchers have shown ordinary human brain cells may share the prized qualities of self-renewal and adaptability normally associated with stem cells. view more (2006-08-17)
GABA halts stem cell production in the brain
Release of the neurotransmitter GABA by adult neuronal precursor cells that develop into neurons limits stem cell proliferation, according to a study at Yale School of Medicine in the September issue of Nature Neuroscience. view more (2005-09-02)
Prozac's target revealed
Researchers at Cold Spring Harbor Laboratory on Long Island have identified which among several different kinds of cells in the brain is the chief target of the widely prescribed antidepressant Prozac. view more (2006-05-16)
Dopamine drug leads to new neurons and recovery of function in rat model of Parkinson's
In preliminary results, researchers have shown that a drug which mimics the effects of the nerve-signaling chemical dopamine causes new neurons to develop in the part of the brain where cells are lost in Parkinson's disease (PD). view more (2006-07-05)
Life and death in the hippocampus: what young neurons need to survive
Whether newborn nerve cells in adult brains live or die depends on whether they can muscle their way into networks occupied by mature neurons. view more (2006-08-14)
Weizmann Institute suggests that immune cells help to maintain cognition and brain cell renewal
A team of scientists at the Weizmann Institute of Science, led by Prof. Michal Schwartz of the Neurobiology Department, has come up with new findings that may have implications in delaying and slowing down cognitive deterioration in old age. view more (2006-01-16)
Stem Cell Activity Deciphered in the Aging Brain
Neurobiologists have discovered why the aging brain produces progressively fewer new nerve cells in its learning and memory center. The scientists said the finding, made in rodents, refutes current ideas on how long crucial "progenitor" stem cells persist in the aging brain. view more (2006-12-19)
Prozac improves learning and memory in fatal brain disease
Howard Florey Institute scientists in Melbourne have found that fluoxetine (commonly marketed as Prozac®) not only improves depression in Huntington's disease, but also improves learning and memory. view more (2005-10-07)
Schizophrenia-linked gene keeps new adult brain cells under control
A gene with reported links to schizophrenia and other mood disorders plays a broader role in the brain than scientists had previously suspected. view more (2007-09-07)
Cellular cues identified for stroke recovery
When a stroke strikes, the supply of blood to the part of the brain affected is interrupted, starving it of oxygen. Brain cells can be seriously damaged or die, impairing local brain function. view more (2006-12-26)
Stress and nerve cells survival in rats; finding may open widow for depression treatment
A single, socially stressful situation can kill off new nerve cells in the brain region that processes learning, memory, and emotion, and possibly contribute to depression, new animal research shows. view more (2007-03-14)
Protein can nurture or devastate brain cells, depending on its 'friends,' researchers find
Researchers at UT Southwestern Medical Center have uncovered new insights into the "Dr. Jekyll and Mr. Hyde" nature of a protein that stimulates stem-cell maturation in the brain but, paradoxically, can also lead to nerve-cell damage. view more (2008-11-12)
Blueberry and green tea containing supplement protects against stroke damage
A unique dietary supplement called NutraStem ® has been shown to have beneficial effects following experimental stroke. A nutritional supplement product, NutraStem also known as NT-020, is a proprietary formulation of blueberry, green tea, vitamin D3 and carnosine extracts- a combination of nutritional ingredients thought to be potent in... view more...

Research Explains How Lead Exposure Produces Learning Deficits
A study of young adult rats by researchers from the Johns Hopkins Bloomberg School of Public Health provides evidence that explains exactly how exposure to lead during brain development produces learning deficits. view more (2007-04-04)
Brain size may depend upon how neural cells are cleaved
Howard Hughes Medical Institute researchers have discovered a novel way in which the brain size of developing mammals may be regulated. They have identified a signaling pathway that controls the orientation in which dividing neural progenitor cells are cleaved during development. view more (2005-07-15)
