New research suggests that rats experience regret, like humans.

By Tanya Lewis Just as humans lament not pursuing a lover or bemoan having eaten that extra slice of chocolate cake, rats may experience feelings of regret, too, new research suggests. When rats were given the option of visiting rooms that contained different foods, and they skipped a good deal for a worse one, theyContinue reading “New research suggests that rats experience regret, like humans.”

New research on adult neurogenesis shows that about 1,400 new brain cells are born every day, and about 80% of human brain cells in the dentate gyrus of the hippocampus undergo renewal in adulthood

by Leonie Welberg The question of whether adult neurogenesis occurs in the human hippocampus has been a hotly debated topic in neuroscience. In a study published in Cell, Frisén and colleagues now settle the debate by providing evidence that around 1,400 dentate gyrus cells are born in the human brain every day. The authors madeContinue reading “New research on adult neurogenesis shows that about 1,400 new brain cells are born every day, and about 80% of human brain cells in the dentate gyrus of the hippocampus undergo renewal in adulthood”

Researchers at the University of Iowa Discover Internal Trigger for Panic Attack in the Previously Fearless

By JAMES GORMAN Published: February 3, 2013 New York Times In the past few years, scientists have learned a lot about fear from a woman who could not experience it. A rare illness had damaged a part of her brain known as the amygdala and left her eerily unafraid. Both in experiments and in life,Continue reading “Researchers at the University of Iowa Discover Internal Trigger for Panic Attack in the Previously Fearless”

Stanford scientists advance thought-control computer cursor movement

    Stanford researchers have designed the fastest, most accurate mathematical algorithm yet for brain-implantable prosthetic systems that can help disabled people maneuver computer cursors with their thoughts. The algorithm’s speed, accuracy and natural movement approach those of a real arm.     On each side of the screen, a monkey moves a cursor withContinue reading “Stanford scientists advance thought-control computer cursor movement”
