New study reveals brain cell mechanism of alcohol dependence
A study released today reveals a cellular mechanism involved in alcohol dependence. The study, in the May 28 issue of The Journal of Neuroscience, shows that gabapentin, a drug used to treat chronic pain and epilepsy, reduces alcohol intake in alcohol-dependent rats by normalizing chemical communication between neurons, which is altered by chronic alcohol abuse.

When your memories can no longer be trusted
You went to a wedding yesterday. The service was beautiful, the food and drink flowed and there was dancing all night. But people tell you that you are in hospital, that you have been in hospital for weeks, and that you didn’t go to a wedding yesterday at all.

Olfactory receptor neurons select which odor receptors to express
It may appear difficult to reconcile the fact that almost every cell in the body of an animal has an identical dose of genes with the variety of different appearances and properties cells can display—bone, skin, hair, muscle, and many more. This may seem even more complex given that all of these tissue types derive originally from a single fertilized egg cell.

Food-Related Clock in the Brain Identified
In investigating the intricacies of the body’s biological rhythms, scientists at Beth Israel Deaconess Medical Center (BIDMC) have discovered the existence of a “food-related clock” which can supersede the “light-based” master clock that serves as the body’s primary timekeeper.

Sleep-deprived brains alternate between normal activity and 'power failure'
New imaging research shows that brain activity differs in sleep-deprived and well-rested people. The study, in the May 21 issue of The Journal of Neuroscience, shows that individuals who are sleep-deprived experience periods of near-normal brain function, but these periods are interspersed with severe drops in attention and visual processing.

Scientists discover a molecular scaffold that guides connections between brain cells
Brain cells known as neurons process information by joining into complex networks, transmitting signals to each other across junctions called synapses. But “neurons don’t just connect to other neurons,” emphasizes Z. Josh Huang, Ph.D., “in a lot of cases, they connect to very specific partners, at particular spots.”

Crystal (eye) ball: Study says visual system equipped with 'future seeing powers'
Catching a football. Maneuvering through a room full of people. Jumping out of the way when a golfer yells “fore.” Most would agree these seemingly simple actions require us to perceive and quickly respond to a situation. Assistant Professor of Cognitive Science at Rensselaer Polytechnic Institute Mark Changizi argues they require something more—our ability to foresee the future.

Researchers discover new link to schizophrenia
Neuroscientists at Johns Hopkins have discovered that mice lacking an enzyme that contributes to Alzheimer disease exhibit a number of schizophrenia-like behaviors. The finding raises the possibility that this enzyme may participate in the development of schizophrenia and related psychiatric disorders and therefore may provide a new target for developing therapies.
