Researchers at the Center for Molecular and Behavioral Neuroscience (CMBN) at Rutgers University in Newark have identified the need to develop a new framework for understanding “perceptual stability” and how we see the world with their discovery that visual input obtained during eye movements is being processed by the brain but blocked from awareness.
The process of seeing requires the eyes to move so light can hit the photoreceptors at the center of each retina, which then pass that information to the brain 
Most common brain cancer may originate in neural stem cells

University of Michigan scientists have found that a deficiency in a key tumor suppressor gene in the brain leads to the most common type of adult brain cancer. The study, conducted in mice that mimic human cancer, points the way to more effective future treatments and a way to screen for the disease early.
Appearing June 2 in Cancer Cell, the U-M team's findings in mice show for the first time that:
Glioblastoma, the type of cancer that afflicts U.S. Sen
Caltech scientists reveal how neuronal activity is timed in brain's memory-making circuits

Theta oscillations are a type of prominent brain rhythm that orchestrates neuronal activity in the hippocampus, a brain area critical for the formation of new memories. For several decades these oscillations were believed to be "in sync" across the hippocampus, timing the firing of neurons like a sort of central pacemaker. A new study conducted by researchers at the California Institute of Technology (Caltech) argues that this long-held assumption needs to be revised
Level Of Cellular Stress Determines Longevity Of Retinal Cells

Stress can be adaptive. It can make you sharper, help you focus and it can even improve your performance. But too much of it can tax cells to the point where they can no longer cope and slowly self-destruct.
Cell's split personality is a major discovery into neurological diseases

Researchers at the Université de Montreal (UdeM) and the Montreal Neurological Institute (MNI), McGill University have discovered that cells which normally support nerve cell (neuron) survival also play an active and major role in the death of neurons in the eye. The findings, published this week in The Journal of Neuroscience, may lead to more streamlined therapies for a variety of acute and chronic neurological disorders, including glaucoma and retinal artery occlusion
Neuroscientists discover long-term potentiation in the olfactory bulb

Ben W. Strowbridge, Ph.D, associate professor of Neuroscience and Physiology/Biophysics, and Yuan Gao, a Ph.D. student in the neurosciences program at Case Western Reserve University School of Medicine, are the first to discover a form of synaptic memory in the olfactory bulb, the part of the brain that processes the sense of smell.
Their study, entitled "Long-term plasticity of excitatory inputs to granule cells in the rat olfactory bulb" will be published in the June 2009 issue of Nature Neuroscience and is currently available online
Neurons Destroyed By Three Simultaneous Strikes

In a study that reveals the clearest picture to date of neuron death in Parkinson's disease, researchers at Columbia University Medical Center have found that a trio of culprits acting in concert is responsible for killing the brain cells.
Researchers discover that gene switches on during development of epilepsy

A discovery made by researchers at Wake Forest University School of Medicine while studying mice may help explain how some people without a genetic predisposition to epilepsy can develop the disorder.
In a study published this month in the Journal of Neuroscience, senior researcher Dwayne W. Godwin, Ph.D
Agents That Speed Up Destruction of Proteins Linked to Alzheimer's Discovered

Taking a new approach to the treatment and prevention of Alzheimer's disease, a research team led by investigators at the Mayo Clinic campus in Florida has shown that druglike compounds can speed up destruction of the amyloid beta (A-beta) proteins that form plaque in the brains of patients with the disorder.
How the brain translates memory into action

When we emerge from a supermarket laden down with bags and faced with a sea of vehicles, how do we remember where we've parked our car and translate the memory into the correct sequence of footsteps and shifts of weight to get back to it? A paper in this week's PLoS Biology identifies the specific parts of the brain responsible for solving this everyday problem. These results could have implications for understanding the functional significance of a prominent brain abnormality observed in neuropsychiatric diseases such as schizophrenia
Closer Look at Einstein's Brain

When a rare genius like Albert Einstein comes along, scientists naturally wonder if he had something special between his ears. The latest study of Einstein's brain concludes that certain parts of it were indeed very unusual and might explain how he was able to go where no physicist had gone before when he devised the theory of relativity and other groundbreaking insights. The findings also suggest that Einstein's famed love of music was reflected in the anatomy of his brain

A collaboration between more than seventy researchers across the globe has uncovered nine new genes on the X chromosome that, when knocked out, lead to learning disabilities. This international team studied almost all the X chromosome genes in 208 families with learning disabilities--the largest screen of this type ever reported.
Remarkably, the team also found that approximately 1% of X chromosome genes have no apparent effect on an individual's ability to function in the ordinary world
Scripps scientists uncover mimicry at the molecular level that protects genome integrity

This study draws new parallels between the Rad60 DNA repair factor and SUMO, a small ubiquitin-like modifier, both of which are essential to maintaining genome stability during replication. The study was published on April 12, 2009 in an advanced online edition of the Nature Structural & Molecular Biology,
"This collaborative study between our laboratory and the Scripps Research Tainer group shows the very first indication of mimicry in the SUMO pathway," said Scripps Research Assistant Professor Michael "Nick" Boddy, Ph.D., senior author of the study
Baby's First Dreams: Sleep Cycles of the Fetus

After about seven months growing in the womb, a human fetus spends most of its time asleep. Its brain cycles back and forth between the frenzied activity of rapid eye movement (REM) sleep and the quiet resting state of non-REM sleep. But whether the brains of younger, immature fetuses cycle with sleep or are simply inactive has remained a mystery until now
Stem Cell Breakthrough May Lead to MS Treatments
