2013-11-21 13:12:19

University of Leicester A team of scientists has shown how the environment shapes learning and memory by training locusts like Pavlov's dog to associate different smells with reward or punishment. Desert locusts are notorious for their devastating swarms. However, they do not always live in swarms — they switch between a lone living 'solitary phase' and a swarming 'gregarious' phase. The two phases differ profoundly in looks, behavior and in their life style. The new research from...
