Scientists identify switch for brain's natural anti-oxidant defense
10-19-2006 · EurekAlert!Scientists at Dana-Farber Cancer Institute report they have found how the brain turns on a system designed to protect its nerve cells from toxic "free radicals," a waste product of cell metabolism that has been implicated in some degenerative brain diseases, heart attacks, strokes, cancer and aging.

- Feinstein researchers develop new genetic method and identify novel genes for schizophrenia
12-03-2007 · EurekAlert!
Scientists at the Zucker Hillside Hospital campus of the Feinstein Institute for Medical Research have identified nine genetic markers that can increase a person's risk for schizophrenia. In a study published this week in the Proceedings of the National Academy of Sciences, the research team uncovered original evidence that this disabling brain disease can be inherited in a recessive manner. A recessive trait is one that is inherited from both parents.

- Scientists identify 2 distinct Parkinson's networks
07-09-2007 · EurekAlert!
Parkinson's that causes tremors, rigidity and slowed movements also targets another brain network that regulates cognitive thought and the ability to carry out everyday tasks. David Eidelberg, MD, head of the Center for Neurosciences at the Feinstein Institute for Medical Research, and his colleagues measured and quantified this network of brain regions during a five-year study of newly diagnosed Parkinson's patients who agreed to be followed several times over the course of the study.

- Do I know you? QBI researchers identify woman's struggle to recognize new faces
07-23-2007 · EurekAlert!
A young woman -- who is by every other measure healthy and intelligent but struggles to recognise new faces -- has presented Queensland Brain Institute (QBI) scientists with fascinating new insights into learning and memory.

- Carnegie Mellon University scientists identify genes activated during learning and memory
04-18-2007 · EurekAlert!
Researchers have long recognized that for learning and memory to take place, certain genes must be activated to alter neuron activity inside the brain. But identifying and cataloging all the genes involved in learning is a daunting task. In the March 13 issue of BMC Neuroscience, Carnegie Mellon University scientists show how an innovative computational approach can provide a rapid way to identify the likely members of this long sought-after set of genes.

- Draining away brain's toxic protein to stop Alzheimer's
08-12-2007 · EurekAlert!
Scientists have shown how the body's natural way of ridding the body of the toxic protein amyloid-beta is flawed in people with the disease. Then the team demonstrated an experimental method in mice to fix the process, dramatically reducing the levels of the toxic protein in the brain and halting symptoms.

- New brain mechanism identified for interpreting speech
12-19-2007 · EurekAlert!
In conversation, humans recognize words primarily from the sounds they hear. However, scientists have long known that what humans perceive goes beyond the sounds and even the sights of speech. The brain constructs its own unique interpretation. In a study in the Dec. 20 issue of Neuron, researchers at the University of Chicago identify brain areas responsible for this perception. One of these areas, Broca's region, is typically thought of as an area of the brain used for talking rather than listening.

- Natural protein stops deadly human brain cancer in mice
12-07-2006 · EurekAlert!
Scientists from Johns Hopkins and from the University of Milan have effectively proven that they can inhibit lethal human brain cancers in mice using a protein that selectively induces positive changes in the activity of cells that behave like cancer stem cells. The report is published this week in Nature.

- Brain's timing linked with timescales of the natural visual world
09-05-2007 · EurekAlert!
Researchers have long attempted to unravel the code used by the neurons of the brain to represent our visual world. By studying the way the brain rapidly and precisely encodes natural visual events that occur on a slower timescale, a team of Harvard bioengineers and brain scientists from the State University of New York have moved one step closer towards solving this riddle.

- Scientists identify 36 genes, 100 neuropeptides in honey bee brains
10-25-2006 · EurekAlert!
From humans to honey bees, neuropeptides control brain activity and, hence, our behaviors. Understanding the roles these peptides play in the life of a honey bee will assist researchers in understanding the roles they play in their human counterparts.

- Alzheimer's prevention role discovered for prions
07-03-2007 · EurekAlert!
A role for prion proteins, the much debated agents of mad cow disease and vCJD, has been identified. It appears that the normal prions produced by the body help to prevent the plaques that build up in the brain to cause Alzheimer’s disease. The possible function for the mysterious proteins was discovered by a team of scientists led by Medical Research Council funded scientist Professor Nigel Hooper of the University of Leeds.
