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.
