| Research Abstract |
In the pond snail Lymnaea stagnalis, the neural circuitry underlying feeding is well described. I here studied the insulin-regulated mechanism affecting feeding behavior in the central nervous system (CNS) of Lymnaea. First, I examined the gene expression of molluscan insulin-related peptide II(MIPII) in the CNS. As a result, several days of hunger or satiation did not have effects on gene expression of MIPII. More, the feeding response to sucrose did not correlate to MIPII gene expression. Next, I examined to identify the neurons that respond to insulin or sucrose application to animals. The neurons that respond to those stimuli were in the buccal ganglia that contain the neural circuitry for feeding.
