Scientists discover ancient brain cells that help block distractions

Scientists have uncovered a fascinating group of neurons in an ancient part of the brain that acts as a natural focus filter, helping to ignore distractions and keep the brain on task. This discovery, made by observing the effects on mice when these neurons were temporarily deactivated, reveals a potential link to attention disorders like ADHD. Understanding these neurons could lead to new treatments for improving focus and managing attention-related issues in humans, highlighting the importance of ancient brain regions in modern cognitive functions.
