Researchers unravel mystery behind long-lasting memories
A new study by researchers at Wake Forest University School of Medicine may reveal how long-lasting memories form in the brain. view more (2009-08-12)
Scientists show how thinking can harm brain cells
Scientists at the University of Rochester Medical Center have targeted a new culprit and method of attack on neurologic functions in diseases such as Alzheimer's and dementia associated with HIV. view more (2005-11-04)
Study of marine snail leads to new insights into long-term memory
UCLA cellular neuroscientists are providing new insights into the mechanisms that underlie long-term memory - research with the potential to treat long-term memory disorders. view more (2008-06-20)
Researchers develop mouse model of autism spectrum disorders
Howard Hughes Medical Institute researchers have genetically engineered mice that harbor the same genetic mutation found in some people with autism and Asperger syndrome. view more (2007-09-07)
Stopping a receptor called 'nogo' boosts the synapses
New findings about a protein called the nogo receptor are offering fresh ways to think about keeping the brain sharp. view more (2008-03-19)
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)
What makes an axon an axon?
Inside every axon is a dendrite waiting to get out. Hedstrom et al. converted mature axons into dendrites by banishing a protein crucial for neuron development. view more (2008-11-10)
Role of noise in neurons
Addressing a current issue in neuroscience, Aldo Faisal and Simon Laughlin from Cambridge University investigate the reliability of thin axons for transmitting information. They show that noise effects in ion channels in the brain are much larger than previously assumed - meaning the fidelity of transmission is compromised. view more (2007-05-04)
Penn researchers discover initial steps in the development of taste
Of the five senses, taste is one of the least understood, but now researchers at the University of Pennsylvania School of Medicine have come one step closer to understanding how the sense of taste develops. view more (2006-12-06)
UCSF research pinpoints brain molecule's role in developing addiction
A molecule in the brain essential for wakefulness and appetite has been found to play a central role in strengthening the neuron connections that lead to addiction. view more (2006-02-16)
Cholesterol metabolism links early- and late-onset Alzheimer's disease
Although the causes of Alzheimer's disease are not completely understood, amyloid-beta (A-beta) is widely considered a likely culprit - the "sticky" protein clumps into plaques thought to harm brain cells. view more (2007-10-05)
MIT robotic therapy holds promise for cerebral palsy
Over the past few years, MIT engineers have successfully tested robotic devices to help stroke patients learn to control their arms and legs. Now, they're building on that work to help children with cerebral palsy. view more (2009-05-21)
New insight into machinery of immune cells' 'tentacles'
Researchers have identified new molecular components of the machinery that regulates formation of the tentacle-like filaments by which immune system T cells grasp other cells. view more (2006-01-10)
Popular antidepressant associated with a dramatic increase in suicidal thoughts amongst men
Nortriptyline has been found to cause a ten-fold increase in suicidal thoughts in men when compared to its competitor escitalopram. These findings are published in the open access journal BMC Medicine. view more (2009-10-15)
Clinical tests begin on medication to correct Fragile X defect
NIH-supported scientists at Seaside Therapeutics in Cambridge, Mass., are beginning a clinical trial of a potential medication designed to correct a central neurochemical defect underlying Fragile X syndrome, the most common inherited cause of intellectual disability. view more (2009-11-03)
Tracing the formation of long-term memory
The formation of long-term memory in fruit flies can be demonstrated by the influx of calcium into cells called mushroom body neurons that occurs after special training that includes periods of rest, said researchers from Baylor College of Medicine (BCM) in a report that appears in the current issue of the journal Neuron. view more (2006-12-07)
'Hub' of fear memory formation identified in brain cells
A protein required for the earliest steps in embryonic development also plays a key role in solidifying fear memories in the brains of adult animals, scientists have revealed. An apparent "hub" for changes in the connections between brain cells, beta-catenin could be a potential target for drugs to enhance or interfere with memory... view more... (2008-09-29)
Alteration of brain protein regulates learning
Researchers at UT Southwestern Medical Center have identified a biochemical switch that affects how neurons fire in a part of the brain associated with learning, findings that may aid in understanding schizophrenia and Alzheimer's disease. view more (2005-08-18)
Turn back, wayward axon
To a growing axon, the protein RGMa is a "Wrong Way" sign, alerting it to head in another direction. As Hata et al. demonstrate in the March 9, 2009 issue of the Journal of Cell Biology, translating that signal into cellular action requires teamwork from two receptors. view more (2009-03-09)
Dynamic molecular mechanism to keep brain activity stable
In the brain, many types of synaptic proteins are spatio-temporally regulated to maintain synaptic activity at a constant level. view more (2009-07-13)
