Applying a shock to the tail of the Aplysia increases responding to stimulation of both the siphon and mantle. This is because the shock leads to the release of neurotransmitters throughout the animal's nervous system, which enhances synaptic transmission and increases excitability in sensory and motor neurons involved in the siphon and mantle withdrawal reflexes.
