People with Alzheimer's disease suffer from severe memory loss and often have problems focusing, reasoning, and communicating. About half of all Alzheimer's patients also experience delusions and hallucinations, this is called Alzheimer's disease with psychosis, and scientists at the University of Pittsburgh are learning more about this severe version of the disease.   In a recent study, researchers at Dr. Robert Sweet's lab zeroed in on a...

After an initial spinal cord injury, a cascading series of secondary events continues to do damage to the nervous system. One particularly damaging event is the death of oligodendrocytes—neuroglial cells that help protect and support the central nervous system. Scientists are learning more about the mechanisms involved in this process in the hope that their research may lead to the development of new therapeutic treatments...

The deepest parts of the ocean are dark. For marine animals living one thousand feet below sea level and lower, the absence of light makes it challenging to find food, attract a mate, and identify predators.   Some animals make their own light through a process called bioluminescence. Others have adapted in ways that help them detect light in an environment beyond the reach of the sun's...

The human brain undergoes extraordinary development in utero, with major growth continuing throughout childhood, especially during the first year. Scientists know a lot about how the neurons and circuits of the human brain develop in infancy, but a lack of specific knowledge about key elements has left doctors mystified by certain childhood disorders like SIDS and autism.   Neuroscientists at Ludwig-Maximillians-University of Munich have made new revelations...

[caption id="attachment_5185" align="aligncenter" width="584"] The granule cell layer of the dentate gyrus. Image provided by Mark Maynard.[/caption] Binge drinking damages brain regions responsible for memory, decision-making, and behavioral control. After a binge, the brain begins to heal itself but not much is known about this self-repair process. In a study published in PLoS ONE, researchers used rats to find that binge drinking damages the hippocampus, and...

Social isolation is stressful. Scientists have known it for decades. They also know that isolation causes changes to occur in the brains of rodents and primates. But most studies examine the effects of isolation during childhood; and the ones that do focus on adulthood tend to use male subjects. For the first time, researchers in Spain show that long-term social isolation causes part of the...

A montage of three images of single striatal neurons transfected with a disease-associated version of huntingtin, the protein that causes Huntington's disease; By: Dr. Steven Finkbeiner, Gladstone Institute of Neurological Disease, The Taube-Koret Center for Huntington's Disease Research, and the University of California San Francisco; licensed under the Creative Commons Attribution 3.0 Unported license.   Patients with Huntington's disease deteriorate physically, cognitively, and emotionally. There is no cure for the inherited...

Foods like tuna fish and Brazil nuts are rich in selenium, a mineral that scientists say has antioxidant effects, keeping the brain healthy and free of clutter so cells can work smoothly together. A key element of this process is Selenoprotein P (Sepp1) – a protein that delivers selenium to neurons by binding with another protein – ApoER2. Neuroscientists at the University of Hawaii say...
