Characterization of sleep in Aplysia californica.

ABSTRACT:

Study objective

To characterize sleep in the marine mollusk, Aplysia californica.

Design

Animal behavior and activity were assessed using video recordings to measure activity, resting posture, resting place preference, and behavior after rest deprivation. Latencies for behavioral responses were measured for appetitive and aversive stimuli for animals in the wake and rest states.

Setting

Circadian research laboratory for Aplysia.

Patients or participants

A. californica from the Pacific Ocean.

Interventions

N/A.

Measurements and results

Aplysia rest almost exclusively during the night in a semi-contracted body position with preferential resting locations in the upper corners of their tank. Resting animals demonstrate longer latencies in head orienta
