Brain's Internal Ruler
MIT researchers have identified a specific neural circuit in the mouse brainstem that processes whisker sensations to map peripersonal space. This discovery explains how animals navigate their immediate surroundings by using whiskers as a biological ruler.
Why it matters
Understanding these neural mechanisms provides insights into how brains construct spatial awareness, which could influence future robotics and neuroscience research.
