When the gill-with-drawal reflex was repeatedly evoked by a tactile stimulus to the siphon or mantle shelf, the amplitude of the response showed marked decrement (habituation). WebShocking the tail (unconditioned stimulus) results in depolarization of the gill motor neuron and a gill withdrawal reflex ; This paired with sensory neuron activity results in glutamate release at the same time as depolarization of post-synaptic motor neuron.
