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)
New mouse model of depression/anxiety enhances understanding of antidepressant drugs
A recent study finds that the antidepressant effects of drugs like Prozac involve both neurogenesis-dependent and -independent mechanisms, a finding that may lead to development of better treatments for depression and anxiety. view more (2009-05-28)
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 mechanisms regulating these distinct cellular activities... 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 development could be shared by insects and mammals. view more (2008-02-19)
Prostate cancer spurs new nerves
Prostate cancer - and perhaps other cancers - promotes the growth of new nerves and the branching axons that carry their messages, a finding associated with more aggressive tumors, said researchers from Baylor College of Medicine in the first report of the phenomenon that appears today in the journal Clinical Cancer Research. view more (2008-12-01)
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 out information and increasing the time it takes... 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 response to antidepressive medications for anxiety or... view more...

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)
Newborn brain cells show the way
Although the fact that we generate new brain cells throughout life is no longer disputed, their purpose has been the topic of much debate. view more (2009-07-10)
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 as the greatest enemy to good health, well-being,... 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 mechanisms for depression. 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)
Brain chemical reduces anxiety, increases survival of new cells
New research on a brain chemical involved in development sheds light on why some individuals may be predisposed to anxiety. view more (2009-05-13)
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)
