The brain cells you see in the above image help an African fish decode electric signals to spot prey, scan its murky surroundings and communicate with its fellows. By rigorously mapping how these cells in the electrosensory lobe are wired together, scientists at Columbia's Zuckerman Institute and th eir colleagues reveal how this brain area continually learns to filter out interference that would otherwise blind the fish's electric sense. They report their findings in Nature. ...read more read less
