Description
The physiological effect of antennular flicking was analyzed
behaviorally and electrophysiologically in the spiny
lobster, Panulirus argus. Behavioral studies indicate
that glycine and L-glutamic acid cause a transient
concentration-dependent increase in flick rate. Electro-physiological
analysis of primary chemosensory afferents
indicates that flicking modulates ongoing chemically-elicited
activity in approximately half of the units
observed by causing either a brief increase or decrease
in the frequency of impulses. Responses of remaining units
were not altered by flicking. Antennular flicking is
discussed as a mechanism to prolong the address of the
peripheral chemoreceptors to the central nervous system
and allow the lobster to prolong its awareness of the
chemical environment.
