In a behaving animal a fundamental challenge for sensory systems is the processing of self-generated sensory information and information from the environment that occurs simultaneously in the same pathway. A central-nervous solution to this problem is corollary discharge activity (efference copy) that is driven by the animal’s own motor commands and interferes with the ongoing sensory processing. In crickets, which constantly expose their auditory pathway to their own song when calling for a female, an identified corollary discharge interneuron (CDI) mediates inhibition to the auditory pathway in phase with the rhythmic sound production. My ongoing research addresses the question how the CDI is activated (identification of interneurons of the cricket singing pattern generator and their connections to the CDI) and how the CDI affects sensory pathways other than the auditory pathway.

Fictive singing activity is monitored by extracellular recording of opener and closer motoneuron spikes in one of the wing nerves (right fig., upper trace).
