Quizplus · Accepted Answer

Short-term habituation in Aplysia is caused by the temporary depletion of available neurotransmitter in the presynaptic sensory neuron, specifically the sensory neuron that triggers the gill withdrawal reflex. This results in a decreased release of neurotransmitter and reduced responsiveness of the motor neuron serving the gill muscle.
