Experiment 3: Group mean (±sem} waveforms illustrating anticipatory activity in response to scheduled mating.

<p>A. Baseline week, no scheduled mating. B. Week 4, late night mating (ZT21}. C. Week 4, daytime mating (ZT6}. D. Day 2 of constant dark without scheduled mating, after the daytime mating schedule. The black curve represents activity detected by the overhead motion sensor. The purple curve (with error bars below} represents activity in the tube to the locked cage. The red curve (with error bars above} represents activity in the tube to the mating cage. Scheduled mealtime is denoted by the opaque vertical bars with dashed red borders. The time of food availability is indicated by the heavy blue line at the top of each figure.
