Influences of Motor Systems on Electrosensory Processing
The first central stage of electrosensory processing in fish has proven to be a particularly useful model system for examining the general issue of how motor systems and behavior influence sensory processing. This chapter reviews this literature, focusing on a substantial body of work elucidating the synaptic, cellular, and circuit mechanisms for predicting and canceling self-generated sensory inputs. Some additional functions of motor corollary discharge signals in weakly electric mormyrid fish are also discussed along with the implications of studies on electrosensory systems for other sensory modalities and brain structures, including the auditory system and the cerebellum.
