Over the last few years, researchers have used a type of brain scanning, known as functional magnetic resonance imaging fMRI, to help them map changes in blood flow in the brain and to correlate this with thoughts and behavior. A new way to analyze …
Gastric bypass surgery decreases the preference for sweet-tasting substances in obese rats, a study finding that could help in developing safer treatments for the morbidly obese, according to Penn State College of Medicine researchers.

MEDFORD/SOMERVILLE, Mass.–Biologists at Tufts University School of Arts and Sciences have discovered that a change in membrane voltage in newly identified “instructor cells” can cause stem cells’ descendants to trigger melanoma-like growth in p…
WASHINGTON, DC — Researchers at the Center for Neuroscience Research at Children’s National Medical Center have discovered that the two major types of signaling pathways activated during brain cell development — the epidermal growth factor recepto…
Researchers at New York University’s Center for Neural Science have identified a new neurological deficit behind amblyopia, or “lazy eye.” Their findings, which appear in the most recent issue of the Journal of Neuroscience, shed additional light on…
Irvine, Calif., Aug. 19, 2010 — A UC Irvine study is the first to demonstrate that human neural stem cells can restore mobility in cases of chronic spinal cord injury, suggesting the prospect of treating a much broader population of patients.

How does the body know it has had an ejaculation? And why does it care? Anatomically, it is more complex than it seems, says the University of Cincinnati scientist who last year identified the spinal cord cells that control ejaculation in rats and the neural pathway by which signals travel between the body’s sexual organs to the brain.
How do 30,000 genes in our DNA work together to form a large part of who we are? How do one hundred billion neurons operate in our brain? The huge number of factors involved makes such complex networks hard to crack. Now, a study published in the October 25 issue of Science uncovers a strategy for finding the organizing principles of virtually any network ? from neural networks to ecological food webs or the Internet.
