Brown scientists explain inception of perception in the brain
03-05-2007 · EurekAlert!All of human sensation -- sight, sound, taste -- begins in the brain when information moves from the thalamus to the neocortex. In Nature Neuroscience, Brown University researchers explain how cortical cells get activated during this critical transfer. The findings shed light on the inner workings of the cortex, the biggest part of the brain, and may help explain some forms of irregular electrical brain activity such as epileptic seizures.

- VEGF neutralization can damage brain vessels, say Schepens Eye Research Institute scientists
02-12-2008 · EurekAlert!
New research by scientists at Schepens Eye Research Institute may help explain why the anticancer drug Avastin, which targets a growth factor responsible for creation of new blood vessels, causes potentially fatal brain inflammation in certain patients. Institute scientists mimicked the drug's activity in mice and found that it damaged the cell lining that prevents fluid from leaking from the ventricle into the brain.

- Language center of the brain is not under the control of subjects who 'speak in tongues'
10-30-2006 · EurekAlert!
Glossolalia, otherwise referred to as "speaking in tongues," has been around for thousands of years, and references to it can be found in the Old and New Testaments. Now, in a first of its kind study, scientists are shining the light on this mysterious practice -- attempting to explain what actually happens physiologically to the brain of someone while speaking in tongues.

- Williams Syndrome, The Brain And Music
10-05-2006 · ScienceDaily
Children with Williams syndrome, a rare genetic disorder, just love music and will spend hours listening to or making music. A study by a multi-institutional collaboration of scientists, published in a forthcoming issue of NeuroImage, identified structural abnormalities in a certain brain area of people afflicted with Williams syndrome. This might explain their heightened interest in music and, in some cases, savant-like musical skill.

- 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.

- Morphine makes lasting -- and surprising -- change in the brain
04-25-2007 · EurekAlert!
Morphine stops the synapse-strengthening process in the brain known as long-term potentiation at inhibitory synapses, according to new research conducted by Brown University brain scientist Julie Kauer. In Nature, Kauer explains this startlingly persistent effect, which could contribute to addiction and may provide a target for treatments of opioid addiction. The research also supports a provocative theory of addiction as a disease of learning and memory.

- Key to longer life (in flies) lies in just 14 brain cells
09-20-2007 · EurekAlert!
Fruit flies live significantly longer when the activity of the protein p53 is reduced in just 14 insulin-producing cells in their brains, new Brown University research shows. The results put scientists one step closer to understanding caloric restriction, a biochemical process proven to slow aging. Results appear in the Proceedings of the National Academy of Sciences.

- Nerve fibers need specific growth factor chemical to form connections within the brain
11-17-2006 · EurekAlert!
A discovery on how neural circuitry develops to aid proper cerebral cortex activity may help explain the memory and cognitive decline seen in Alzheimer's disease patients -- a discovery that could point toward potential treatments, according to UC Irvine scientists.

- Schizophrenia-linked gene keeps new adult brain cells under control
09-06-2007 · EurekAlert!
A gene with reported links to schizophrenia and other mood disorders plays a broader role in the brain than scientists had previously suspected. The study reveals that the gene, known as Disrupted-In-Schizophrenia 1, directs the incorporation of new neurons into the adult brain and keeps the process under control. The gene's newly discovered roles might help to explain why schizophrenia's symptoms generally arise in adolescence or early adulthood, the researchers suggested.

- Anti-cancer drug damages brain vessels
02-11-2008 · EurekAlert!
New research may help explain why an anti-cancer drug causes potentially fatal brain inflammation in certain patients. Scientists at Harvard Medical School mimicked the drug's activity in mice and found that it damaged the cell lining that prevents fluid from leaking from the spinal cord into the brain. The results will be published online on Feb. 11 in the Journal of Experimental Medicine.

- 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.
