Abstract

Remarkable changes in behaviour and the actions of known neurones in the CNS accompany transition from solitarious to gregarious phases in locusts, which can be induced in 4h by touching particular leg hairs, or electrical stimulation of their nerves. We will reveal the mechanisms of this plasticity and relate them to the acquisition of phase specific behaviours by: 1, using HPLC to determine differences in selected neuroactive substances in the brains and ganglia of the two phases; 2, determining the time course of changes in processing by a visual interneurone and the efficacy of its output connections with leg motor neurones; 3, analysing the differences in food selection by examining taste processing of sensilla and interneurones. (Joint with grant number 19275).
