Abstract

Crayfish, when stimulated, engage in a stereotyped tailflip escape response controlled via three different neuronal circuits. Two circuits are sensory and mediated via command neurons, Medial Giant and Lateral Giant Neurons. The third circuit is not mediated with a command neuron, requiring more integration, which the response more flexible. In all circuits, repeated stimulus leads to reduction of response, or habituation. The neurotransmitter Serotonin (5-HT) has been found to affect the tailflip response by enhancing the response to sensory stimuli. In this study, the habituation rates of these three circuits are compared in crayfish (Procambarus clarkii) with varying levels of 5-HT. Preliminary data indicates the non-command circuit habituates faster.
