Summary

Scientists have identified a group of neurons located in an ancient region of the brain that plays a key role in helping animals focus. These cells appear to improve attention by filtering out distractions and directing the brain toward the most important information. The discovery, made in mice by researchers at Johns Hopkins University, points to a brain system that is shared by all vertebrates, including humans. The findings could eventually help researchers develop more precise treatments for attention-related disorders.
