Mysterious 'Neural Noise' Actually Primes Brain for Peak Performance
Researchers at the University of Rochester may have answered one of neuroscience's most vexing questions-how can it be that our neurons, which are responsible for our crystal-clear thoughts, seem to fire in utterly random ways? view more (2006-11-13)
Fish oil may help protect against retinal degenerative diseases
A invited paper published in Trends in Neuroscience this week by Nicolas G. Bazan, MD, PhD, Boyd Professor and Director of the Neuroscience Center of Excellence at LSU Health Sciences Center in New Orleans, reports on the role that the omega-3 fatty acids in fish oil play in protecting cells in the retina from degenerative diseases like retinitis... view more...

MIT: Making waves in the brain
Scientists have studied high-frequency brain waves, known as gamma oscillations, for more than 50 years, believing them crucial to consciousness, attention, learning and memory. view more (2009-04-27)
Researchers find ways to encourage spinal cord regeneration after injury
Animal research is suggesting new ways to aid recovery after spinal cord injury. New studies demonstrate that diet affects recovery rate and show how to make stem cell therapies safer for spinal injury patients. view more (2009-10-21)
UCLA Find Yields Further Insight Into Causes of Parkinson's Disease
In humans, a dearth of the neurotransmitter dopamine has long been known to play a role in Parkinson's disease. It is also known that mutations in a protein called parkin cause a form of Parkinson's that is inherited. view more (2007-02-02)
Making sense of the world through a cochlear implant
Scientists at University College London and Imperial College London have shown how the brain makes sense of speech in a noisy environment, such as a pub or in a crowd. The research suggests that various regions of the brain work together to make sense of what it hears, but that when the speech is completely incomprehensible, the brain appears to... view more...

'Electric' fish shed light on ways the brain directs movement
Scientists have long struggled to figure out how the brain guides the complex movement of our limbs, from the graceful leaps of ballerinas to the simple everyday act of picking up a cup of coffee. view more (2007-02-01)
An 'eye catching' vision discovery
Nearly all species have some ability to detect light. At least three types of cells in the retina allow us to see images or distinguish between night and day. Now, researchers at the Johns Hopkins School of Medicine have discovered in fish yet another type of cell that can sense light and contribute to vision. view more (2009-07-27)
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)
Stem cell treatment succeeds in spinal cord-injured rats
Stem cells can repair damaged spinal tissue and help restore function in rats with spinal cord injuries, according to a new study. view more (2006-03-29)
APP -- Good, bad or both?
New data about amyloid precursor protein, or APP, a protein implicated in development of Alzheimer's disease, suggests it also may have a positive role -- directly affecting learning and memory during brain development. view more (2009-10-19)
Blood pressure drug curbs brain damage from PTSD
A drug used to treat high blood pressure and enlargement of the prostate may protect the brain from damage caused by post-traumatic stress disorder, Alzheimer's disease, depression and schizophrenia. view more (2007-11-07)
The musician in the mirror
A new imaging study shows that when we learn a new action with associated sounds, the brain quickly makes links between regions responsible for performing the action and those associated with the sound. view more (2007-01-15)
Origins of nervous system found in genes of sea sponge
Scientists at the University of California, Santa Barbara have discovered significant clues to the evolutionary origins of the nervous system by studying the genome of a sea sponge, a member of a group considered to be among the most ancient of all animals. view more (2007-06-06)
Children with gene show reduced cognitive function
Children who possess a gene known to increase the risk of Alzheimer's disease already show signs of reduced cognitive function, an Oregon Health & Science University study has found. view more (2007-11-06)
New and unexpected mechanism identifies how the brain responds to stress
Chronic stress takes a physical and emotional toll on our bodies and scientists are working on piecing together a medical puzzle to understand how we respond to stress at the cellular level in the brain. view more (2009-03-03)
Live recordings of cell communication
A new advanced method for nano-scale imaging of vesicle-fusion - vesicles are biological nano-sized containers - could add to our understanding of diseases of the nervous system and viral infections. view more (2009-08-06)
Yerkes researchers show early life nurturing impacts later life relationships
Researchers at the Yerkes National Primate Research Center, Emory University, have demonstrated that prairie voles may be a useful model in understanding the neurochemistry of social behavior. view more (2009-09-01)
Moral judgment fails without feelings
Consider the following scenario: someone you know has AIDS and plans to infect others, some of whom will die. Your only options are to let it happen or to kill the person. view more (2007-03-22)
Growth hormone is made in the brain, report scientists
Scientists have found that growth hormone, a substance that is used for body growth, is produced in the brain, according to an article published in this week's Proceedings of the National Academy of Sciences. view more (2006-03-28)
