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)
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)
Mammalian neurogenesis breaks into the most static brain region
ifteen years ago, the discovery of adult neurogenesis (the production of new neurons) in the highly static, non-renewable mammalian brain was a breakthrough in neuroscience. view more (2008-06-04)
Trainor Lab characterizes gene essential for prenatal development of nervous system
The Stowers Institute's Trainor Lab has demonstrated the role of a gene important to the embryonic development of the nervous system, a process that requires coordination of differentiation of immature neural cells with the cycle of cell division that increases their numbers. Until now, the... view more (2008-02-04)
Building brains: Mammalian-like neurogenesis in fruit flies
A new way of generating brain cells has been uncovered in Drosophila. The findings, published this week in the online open access journal Neural Development, reveal that this novel mode of neurogenesis is very similar to that seen in mammalian brains, suggesting that key aspects of neural... view more (2008-02-19)
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)
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... view more (2007-03-30)
Sensitivity to antidepressants linked with TrkB-mediated neural proliferation
Scientists have unveiled a functional link between production of new neurons and the effectiveness of antidepressants (ADs) in an animal model. The study, published by Cell Press in the August 14 issue of the journal Neuron, provides exciting insight into a mechanism that might underlie a poor... view more (2008-08-14)
Exercise increases brain growth factor and receptors, prevents stem cell drop in middle age
A new study confirms that exercise can reverse the age-related decline in the production of neural stem cells in the hippocampus of the mouse brain, and suggests that this happens because exercise restores a brain chemical which promotes the production and maturation of new stem cells. view more (2008-11-18)
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)
Brain cell growth diminishes long before old age strikes, animal study shows
Even early in adulthood, aging begins to slow the mind's growth -- but it does not have to stop it altogether, suggests a Princeton University study on the brains of adult monkeys. view more (2007-10-16)
Relaxation in a flotation tank brings peace and quiet, increased well-being, and reduced pain
A new dissertation shows that relaxation in a flotation tank can serve as an alternative form of treatment to reduce stress or relieve persistent pain, and it has no side-effects whatsoever. In times like these, we are surrounded by stress and troubled by burn-out. Stress seems to retain its place... view more (2003-11-05)
Potential new targets for antidepressant medications
The news about antidepressant medications over the past several years has been mixed. The bad news from large multicenter studies such as STAR*D is that current antidepressant medications are effective, but not as effective as one might hope. Thus, there is a significant need for new treatment... view more (2008-08-27)
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)
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)
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)
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)
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)
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)
