Larvae shun the light
Drosophila larvae avoid light during the foraging stage of their development. Research published in the open access journal BMC Neuroscience shows that both 5-HT (serotonergic) and corazonergic neurons have a role in regulating this behavior. view more (2009-06-23)
Neural signal that helps wire up brain's movement circuit identified
Scientists from Imperial College London and King`s College London have identified a molecule that helps to wire up the neural circuitry responsible for controlling the movement of muscle. Writing today in the journal Neuron, the researchers describe how the signalling protein named WNT-3 directs specific neurons during embryonic development to... view more... (2002-09-10)
New brain cells listen before they talk
Newly created neurons in adults rely on signals from distant brain regions to regulate their maturation and survival before they can communicate with existing neighboring cells-a finding that has important implications for the use of adult neural stem cells to replace brain cells lost by trauma or neurodegeneration, Yale School of Medicine... view more...

Scientists produce neurons from human skin
Scientists from Université Laval's Faculty of Medicine have succeeded in producing neurons in vitro using stem cells extracted from adult human skin. view more (2007-02-23)
Researchers pinpoint molecular basis for phantom pain
Yale researchers report the first evidence that phantom pain following spinal cord injury is the result of hypersensitive neurons in the thalamic region of the brain that can be suppressed with specially designed molecular agents. view more (2005-09-21)
Neurons for numerosity: Parietal neurons 'sum up' individual items in a group
As any child knows, to answer the question "how many," one must start by adding up individual objects in a group. view more (2007-07-24)
A balanced memory network
Ever wonder how much information we put in our heads" The answer: a lot. For starters, a typical vocabulary is 50,000-250,000 words. view more (2007-09-07)
Researchers identify protein needed to develop auditory neurons
Loss of spiral ganglion neurons or hair cells in the inner ear is the leading cause of congenital and acquired hearing impairment. view more (2010-01-13)
Experience affects new neuron survival in adult brain; study sheds light on learning, memory
Experience in the early development of new neurons in specific brain regions affects their survival and activity in the adult brain, new research shows. How these new neurons store information about these experiences may explain how they can affect learning and memory in adults. view more (2007-03-23)
A good ear: Rats identify specific sounds in noisy environments
A study conducted on hundreds of rats could help us understand how the brain identifies specific sounds in a noisy environment. view more (2008-11-19)
Marine snail's neural network sheds light on the basis for flexible behavior
By studying how a relatively simple motor network of the marine snail Aplysia produces variants of a particular feeding behavior, researchers have found that the ability to generate a large number of behavioral variants stems from the elegant hierarchical architecture of the brain's motor network. view more (2005-10-11)
How taste response is hard-wired into the brain
Instantly reacting to the sweet lure of chocolate or the bitter taste of strychnine would seem to demand that such behavioral responses be so innate as to be hard-wired into the brain. view more (2006-01-19)
UMass Lowell researchers' findings suggest new ways to diagnose and treat Alzheimer's
A team of researchers at UMass Lowell has found a new mechanism by which a key protein associated with Alzheimer's disease can spread within the human brain. view more (2010-03-02)
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)
Phasic firing of dopamine neurons is key to brain's prediction of rewards
Researchers are one step closer to understanding the neurobiology that allows people to successfully learn motivated behaviors by associating environmental cues with rewarding outcomes, according to a study published yesterday in the Proceedings of the National Academy of Sciences' online Early Edition. view more (2009-04-06)
Scientists shed new light on walking
Researchers at the medical university Karolinska Institutet have created a genetically modified mouse in which certain neurons can be activated by blue light. view more (2010-01-25)
UCLA stem cells scientists make electrically active motor neurons from iPS cells
Stem cells scientists at UCLA showed for the first time that human induced pluripotent stem (iPS) cells can be differentiated into electrically active motor neurons, a discovery that may aid in studying and treating neurological disorders. view more (2009-02-25)
Identification of dopamine 'mother cells' could lead to future Parkinson's treatments
'Mother cells' which produce the neurons affected by Parkinson's disease have been identified by scientists, according to new research published in the journal Glia. view more (2008-04-08)
A glimmer of hope in the struggle against neurodegenerative diseases: the virtues of proteins that can save dying neurons
Diseases characterized by neurodegeneration affect individuals over 50 years of age and they attack one particular class of neurons in the brain or spinal cord. The research interest of Professor Ann Kato and her team is principally focalized on ALS in which there is a progressive paralysis caused by the destruction of motor neurons which exist in... view more...

Pleasant dietary habits are necessary for health
Japanese research group led by Professor Yasuhiko Minokoshi and Dr. Tetsuya Shiuchi, scientists at the National Institute for Physiological Sciences, NIPS, Japan, found that meals stimulated with sweet taste and motivated with its anticipation regularly activates "orexin" in the brain and it stimulates muscle glucose metabolism via the... view more...
