Research Abstract |
The purpose of this study was functional analysis of the central neural circuit involved in the switch of feeding and egg-laying behavior in Aplysia kurodai. I investigated the effects of the egg-laying hormone(ELH) on the activity of identified buccal neurons using conventional electrophysiological techniques. The modulation in spike activity of buccal motor neurons by ELH will cause early onset of jaw closing. This result suggests that ELH changes the buccal motor program from ingestion to rejection, which contributes to a decrease in food intake during egg-laying behavior.
