Alzheimer’s drug reverses brain damage from adolescent alcohol exposure in rats

A drug used to slow cognitive decline in adults with Alzheimer’s disease appears to reverse brain inflammation and neuron damage in rats exposed to alcohol during adolescence. In a study described in the journal Scientific Reports, Duke Health researchers sought to understand how intermittent binge drinking changes the hippocampus—a region Continue Reading

Non-invasive electrical stimulation alters blood flow in brain tumors

In a first-of-its kind study, neurologists at Beth Israel Deaconess Medical Center (BIDMC) tested the use of non-invasive electrical stimulation as a novel therapeutic approach to brain tumors. In an experiment published in Science Advances, the scientists—led by Emiliano Santarnecchi, Ph.D., principal investigator at the Berenson-Allen Center For Non-Invasive Brain Continue Reading

Brain molecule identified as key in anxiety model

Boosting a single molecule in the brain can change “dispositional anxiety,” the tendency to perceive many situations as threatening, in nonhuman primates, researchers from the University of California, Davis, and the University of Wisconsin-Madison have found. The molecule, neurotrophin-3, stimulates neurons to grow and make new connections. The finding provides Continue Reading

Finding the brain’s compass

The world is constantly bombarding our senses with information, but the ways in which our brain extracts meaning from this information remains elusive. How do neurons transform raw visual input into a mental representation of an object鈥攍ike a chair or a dog? In work published in Nature Neuroscience, MIT neuroscientists Continue Reading

Scientists identify brain region that enables young songbirds to change their tune

In a scientific first, Columbia scientists have demonstrated how the brains of young songbirds become tuned to the songs they learn while growing up. The results of this study, published today in Nature Neuroscience, illustrate the extraordinary flexibility of the growing brain. Because the brain region that listens to sounds, Continue Reading
