Rat

Neuroscientists from the Picower Institute for Learning and Memory at MIT have discovered that after completing a task, a rat’s brain will mentally replay recent events, but in reverse order. They believe this process plays a key role in learning and memory and may explain why taking frequent breaks when studying is more effective for learning new material than cramming for extended periods of time. Their work could yield a better understanding of amnesia, Alzheimer’s disease and other memory disorders and lead to more efficient methods for learning and memorization.

Researchers from the Picower Institute for Learning and Memory at MIT have recently found that contrary to popular belief, neurons do grow in mature brains. It had been widely accepted that structural remodeling of neurons does not occur in adult brains, but the discovery that it does could lead to advances in treatments of spinal cord injuries and other neural damage caused by accidents or disease. The study, co-authored by Elly Nedivi, appears in the December 27th issue of Public Library of Science (PLoS) Biology.
