Matching Sight and Sound in Owl's Brains Could Treat ADHD

Scientific American reports that owl's brains are specially structured to match sights to sounds and home in on targets:
Neurologists Daniel Winkowski and Eric Knudsen of Stanford University wired 12 owls with electrodes in the areas of their brains that process either visual or auditory input. Each region literally maps the world of sound or sight, determining whether it comes from up or down, left or right. Sending a small electrical charge into the owl's visual brain region--the so-called arcopallial gaze fields--caused it to move its head and eyes in a particular direction. When a simultaneous audio stimulus matched that direction, the owl's brain responded more strongly to that noise. It also blocked out competing noises from other directions.
Link. The idea is that this might have implications for the treatment of attentionU+2014hey, what's that over there?
