Abstract

The differential processing of self-generated and external sensory information is a fundamental problem in all sensory pathways. During singing in crickets a corollary discharge presynaptically inhibits the terminals of auditory afferents and postsynaptically the thoracic interneurones. This reduces the response to self- generated sound patterns and serves to maintain the sensitivity of the crickets auditory pathway. The corollary discharge originates from the singing motor network. We will use intracellular recording and staining to identify the neuron mediating the corollary discharge and we will meticulously analyse the impact of the corollary discharge on auditory processing in double recording experiments by driving the corollary discharge neurone while recording the auditory neurons. The experiments will elucidate a basic principle of sensory processing.
