Fig. 8. Neural activity from an afferent anterior lateral line fiber before, during and after a prey strike. Vertical lines on the trace indicate individual action potentials from a single fiber that were discriminated based on spike amplitude. The arrows indicate initiation of opercular contraction for each ventilation cycle. The time during the strike, capture and subsequent expulsion of the prey is boxed in A, and this interval is expanded in B. The prey was retained in the mouth of the toadfish for approximately 1 s before being expelled.
