self generated EODs that would interfere with interpretation of external EODs needed for communication between fish. However, these fish display corollary discharges that inhibit the ascending sensory pathway at the first CNS relay point. These corollary discharges are timed to arrive at the same time as the reafference from the KS to minimize the interference of self-produced EODs with the perception of external EODs, and optimize the duration of inhibition.
