Describe how habituation is demonstrated in memory research on invertebrates?
What will be an ideal response?
Habituation is a decrease in response to a stimulus that is presented repeatedly and accompanied by no change in other stimuli. For example, if your clock chimes every hour, you gradually respond less and less. If we repeatedly stimulate an Aplysia's gills with a brief jet of seawater, it withdraws at first, but after many repetitions, it stops responding. The decline in response is not due to muscle fatigue because, even after habituation has occurred, direct stimulation of the motor neuron produces a full-size muscle contraction (Kupfermann, Castellucci, Pinsker, & Kandel, 1970). We can also rule out changes in the sensory neuron. The sensory neuron still gives a full, normal response to stimulation; it merely fails to excite the motor neuron as much as before (Kupfermann et al., 1970). We are therefore left with the conclusion that habituation in Aplysia depends on a change in the synapse between the sensory neuron and the motor neuron.
