Habituation is the waning of a reflex response to repeated stimulation. Habituation to closely spaced stimuli is faster and more complete than to widely spaced stimuli, but recovery is also more rapid (rate sensitivity). We show that a 2-unit, cascaded-integrator dynamic model can explain in detail an extensive data set on rate-sensitive habituation in the nematode Caenorhabditis elegans. Many apparently complex properties of habituation and learning dynamics may reflect interactions among a small number of processes with different time scales.

D012018	Reflex	An involuntary movement or exercise of function in a part, excited in response to a stimulus applied to the periphery and transmitted to the brain or spinal cord.
D005246	Feedback	A mechanism of communication within a system in that the input signal generates an output response which returns to influence the continued activity or productivity of that system.	Feedbacks
