That notion will soon be explored by dozens of his colleagues from nine specialties who will engage in a robust program of research projects and clinical trials at UVA's new Focused Ultrasound Center, which was dedicated on September 14.
Researchers map common brain wave spikes in dying patients. What do the findings suggest about the workings of our brains as we die.
While the human brain responds very differently to religious and nonreligious propositions, the process of believing or disbelieving a statement, whether religious or not, seems to be governed by the same areas in the brain.
This study suggests that a single gene, called GSK-3, controls the signals that determine how many neurons actually end up composing the brain. This has important implications for patients with neuropsychiatric illness, as links have recently been drawn between GSK-3 and schizophrenia, depression and bipolar disorder.
Two University of Southern California (USC) neuroscientists have been awarded nearly $9 million in American Recovery and Reinvestment Act funds to map how genes are expressed in different regions of the human brain throughout development.

The research, conducted by Grinnell biological chemistry students and led by Mark Levandoski, associate professor of chemistry, examined the family of proteins in the nervous system that respond to nicotine.

The brain never sits idle. Whether we are awake or asleep, watch TV or close our eyes, waves of spontaneous nerve signals wash through our brains. Researchers at the Salk Institute for Biological Studies studying visual attention have discovered a novel mechanism that explains how incoming sensory signals make themselves heard amidst the constant background rumblings so they can be reliably processed and passed on.

In Neurogenic Communication Disorders: Life Stories and the Narrative Self, University of Arkansas researchers challenge readers to explore “the messy but powerful relationships between communication impairment and maintenance of a viable sense of self.”
The belief that healthy older brains are substantially smaller than younger brains may stem from studies that did not screen out people whose undetected, slowly developing brain disease was killing off cells in key areas, according to new research. As a result, previous findings may have overestimated atrophy and underestimated normal size for the older brain.
Researchers from the University of Haifa discover that the addition of the phosphor molecule to a the NMDA receptor in the brain is a necessary step in memory formation
An international team of scientists has identified two more genetic risk factors for Alzheimer's disease. The group, led by investigators from the School of Medicine at Cardiff in the United Kingdom and including scientists from Washington University School of Medicine in St. Louis, completed the largest genome-wide association study ever involving patients with Alzheimer's disease. The study pooled DNA samples from more than 19,000 older European and U.S. residents. Seven thousand had Alzheimer's disease, and the others had no clinical symptoms of the disorder.
