We have examined the effect of a conditioning procedure on various components of visually guided locomotion inHermissenda. Temporally specific stimulation of the visual system and gravity detecting system (statocysts) with light and rotation produced long-term changes in locomotor behavior. We found that the latency to initiate locomotion in the presence of light was significantly increased for the conditioned group as compared to baseline pre-test latencies and groups that received random presentations of the conditioning stimuli. The variability in the time taken by animals to enter a central illuminated area as reported in earlier studies can be accounted for by the increase in the latency to initiate locomotion. The modifications of visually influenced locomotion exhibits stimulus (CS) specificity since locomotor behavior is not changed following conditioning in the absence of light. In addition, conditioned animals remained in the brightest part of the light gradient significantly less than pre-test measurements. Since this response (initiation of locomotion) can be studied in a semi-intact preparation, it should be possible to investigate how this example of learning generates changes in behavior.
