What helps the brain tune out distractions and stay focused on what truly matters? Scientists at Johns Hopkins University believe they may have found part of the answer in one of the brain's oldest regions. The newly identified cells appear to function as a natural filtering system, helping animals ignore competing signals and concentrate on important information. The discovery could eventually reshape how researchers understand attention disorders such as ADHD, as quoted in a report by Science Daily.
The findings, published in Nature Communications, suggest that this mechanism is shared across vertebrates, including humans.
