Small brain -- astounding performance

(University of Bonn) The elephantnose fish explores objects in its surroundings by using its eyes or its electrical sense -- sometimes both together. Zoologists at the University of Bonn and a colleague from Oxford have now found out how complex the processing of these sensory impressions is. With its tiny brain, the fish achieves performance comparable to that of humans or mammals. The advance results have been published online in 'PNAS.'
