Question
At what neural site does habituation of a gill-withdrawn reflex occur in Aplysia?
a. Muscle becomes less responsive to synaptic stimulation by the motor neuron
Both sensory nerve endings in the skin and at the motor neuromuscular junction
Synapse between sensory and motor neuron
Sensory nerve endings in the skin
a. Muscle becomes less responsive to synaptic stimulation by the motor neuron
b.Both sensory nerve endings in the skin and at the motor neuromuscular junction
c.Synapse between sensory and motor neuron
d.Sensory nerve endings in the skin
Explanation / Answer
Habituation is a decrease in behavioral response to a stimulus following repeated exposure to the stimulus with no adverse effect. This habituative response is due to a progressive decrease in the amount of glutamate neurotransmitter released by the siphon sensory neurons at their synapses with the motor neurons.
Therefore answer is (c)
(c)
