Neurons hard wired to tell left from right
It's well known that the left and right sides of the brain differ in many animal species and this is thought to influence cognitive performance and social behaviour. For instance, in humans, the left half of the brain is concerned with language processing whereas the right side is better at comprehending musical melody. view more (2008-03-31)
Researchers at Vanderbilt-Ingram Cancer Center uncover clue to explain invasive brain tumors
Researchers at the Vanderbilt-Ingram Cancer Center have uncovered a clue to explain the invasive nature of an aggressive kind of brain tumor called glioblastoma multiforme, or gliomas. view more (2006-01-12)
Adult neurogenesis newly adult-born neurons are functionally similar to mature neurons
In mammals, the production of new brain cells occurs primarily at the time the nervous system is developing, although certain brain areas generate neurons throughout adulthood. One such area is the hippocampus, a part of the brain involved in the critical function of memory and spatial perception. view more (2006-11-21)
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)
Tumor suppressor gene in flies may provide insights for human brain tumors
In the fruit fly's developing brain, stem cells called neuroblasts normally divide to create one self-renewing neuroblast and one cell that has a different fate. But neuroblast growth can sometimes spin out of control and become a brain tumor. view more (2009-06-23)
New research promising for improving brain cell survival after brain injury
Scientists at Melbourne's Howard Florey Institute have found a protein in the brain that can save neurons from dying after experiencing traumatic brain injury from incidents such as stroke, car accidents and falls. view more (2006-07-11)
The secret of internal bliss revealed
Scientists now know for sure how cannabis works in the brain. By studying naturally occuring cannabinoids they have found that cannabis 'speaks' to nerve cells instructing them to stop releasing their chemical neurotransmitters so dumbing down their effects. The upside is that it makes cannabis effective for treatment of MS but it also has a... view more... (2001-04-03)
MIT: Stem-cell therapies for brain more complicated than thought
An MIT research team's latest finding suggests that stem cell therapies for the brain could be much more complicated than previously thought. view more (2007-11-28)
Nerve cells derived from stem cells and transplanted into mice may lead to improved brain treatments
Scientists at the Burnham Institute for Medical Research have, for the first time, genetically programmed embryonic stem (ES) cells to become nerve cells when transplanted into the brain, according to a study published today in The Journal of Neuroscience. view more (2008-06-25)
Scientists ask whether microscaffolding can help stem cells rebuild brain after stroke damage
Inserting tiny scaffolding into the brain could dramatically reduce damage caused by strokes the UK National Stem Cell Network Annual Science Meeting will hear today (10 April). view more (2008-04-10)
Matrix fragments trigger fatal excitement
Shredded extracellular matrix (ECM) is toxic to neurons. Chen et al. reveal a new mechanism for how ECM demolition causes brain damage. The study will appear in the December 29, 2008 issue of The Journal of Cell Biology (www.jcb.org). view more (2008-12-30)
Neural stem cells offer potential treatment for Alzheimer's disease
UC Irvine scientists have shown for the first time that neural stem cells can rescue memory in mice with advanced Alzheimer's disease, raising hopes of a potential treatment for the leading cause of elderly dementia that afflicts 5.3 million people in the U.S. view more (2009-07-21)
Research links 'ecstasy' to survival of key movement-related cells in brain
New research from the University of Cincinnati (UC) suggests that the widely abused club drug "ecstasy," or MDMA, can increase the survival of dopamine cells in the brain during fetal development. view more (2006-10-19)
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)
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)
New understanding about mechanism for cell death after stroke leads to possible therapy
Scientists at the Brain Research Centre, a partnership of the University of British Columbia Faculty of Medicine and Vancouver Coastal Health Research Institute, have uncovered new information about the mechanism by which brain cells die following a stroke, as well as a possible way to mitigate that damage. view more (2009-11-23)
Harvard scientists identify compounds that stimulate stem cell growth in the brain
cientists at Harvard University have identified key compounds that stimulate stem cell growth in the brain, which may one day lead to restored function for people affected by Parkinson's disease, strokes, multiple sclerosis, and a wide range of neurological disorders. view more (2006-09-01)
Darwin's greatest challenge tackled: the mystery of eye evolution
When Darwin's skeptics attack his theory of evolution, they often focus on the eye. Darwin himself confessed that it was "absurd" to propose that the human eye evolved through spontaneous mutation and natural selection. Scientists at the European Molecular Biology Laboratory (EMBL) have now tackled Darwin's major challenge in an... view more... (2004-10-26)
Brain Structure Assists in Immune Response, According to Penn Vet Study
For the first time, a team of researchers at the University of Pennsylvania School of Veterinary Medicine have imaged in real time the body's immune response to a parasitic infection in the brain. view more (2009-01-29)
Protein's potential as a regulator of brain activity discovered
UC Irvine researchers have found that a protein best known for building connections between nerve cells and muscle also plays a role in controlling brain cell activity. view more (2006-04-21)
