Scientists Use Prosthetic Device to Restore and Improve Impaired Decision Making Ability in Animals

Scientists used an electronic prosthetic system to tap into existing circuitry in the brain at the cellular level and record the firing patterns of multiple neurons in the prefrontal cortex, the part of the brain involved in decision-making. They then “played” that recording back to the same brain area to electrically stimulate decision-based neural activity. Not only did it restore function, in some cases, it also improved it.

How Early Social Deprivation Impairs Long-Term Cognitive Function

A study shows social isolation during early life prevents the cells that make up the brain's white matter from maturing and producing the right amount of myelin, the fatty "insulation" on nerve fibers that helps them transmit long-distance messages within the brain.

Stress Breaks Loops that Hold Short-Term Memory Together

By watching individual neurons at work, a group of psychologists at the University of Wisconsin-Madison has revealed just how stress can addle the mind, as well as how neurons in the brain's prefrontal cortex help remember information in the first place.

Why Are Elderly Duped?

Researchers report they’ve pinpointed the precise location in the human brain, called the ventromedial prefrontal cortex, that controls belief and doubt, and which explains why some of us are more gullible than others.

Brain Development is Delayed in Attention-Deficit/Hyperactivity Disorder

Researchers found that development of the cortical surface is delayed in frontal brain regions in children with ADHD. The typically developing children attained 50% peak area in the right prefrontal cortex at a mean age of 12.7 years, whereas the ADHD children didn’t reach this peak until 14.6 years of age.
