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)
UNC study ties ending moderate drinking to depression
Scientific evidence has long suggested that moderate drinking offers some protection against heart disease, certain types of stroke and some forms of cancer. view more (2008-07-09)
Gene activity reveals dynamic stroma microenvironment in prostate cancer
As stroma - the supportive framework of the prostate gland - react to prostate cancer, changes in the expression of genes occur that induce the formation of new structures such as blood vessels, nerves and parts of nerves. view more (2009-06-09)
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)
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)
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)
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)
CCNY, CSHL biologists find birdsong of isolates reverts to norm over several generations
In an experiment that points to a role for genetics in the development of culture, biologists at The City College of New York (CCNY) and Cold Spring Harbor Laboratory (CSHL) have discovered that zebra finches raised in isolation will, over several generations, produce a song similar to that sung by the species in the wild. view more (2009-05-04)
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)
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)
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...

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)
Growth of new brain cells requires 'epigenetic' switch
New cells are born every day in the brain's hippocampus, but what controls this birth has remained a mystery. Reporting in the January 1 issue of Science, neuroscientists at the Johns Hopkins University School of Medicine have discovered that the birth of new cells, which depends on brain activity, also depends on a protein that is involved in... view more...

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)
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)
Life and death in the living brain
Like clockwork, brain regions in many songbird species expand and shrink seasonally in response to hormones. Now, for the first time, University of Washington neurobiologists have interrupted this natural "annual remodeling" of the brain and have shown that there is a direct link between the death of old neurons and their replacement by... view more...

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)
