Wheel running activity of mice in Experiment 1, Group 3.

<p>(A) Actogram of wheel running from one representative mouse. Vertical bars to the left indicate experimental conditions, as follows: SlimFast, <i>ad libitum</i> access to regular chow, with time limited access to a chocolate flavored SlimFast paste from ZT4-6 (light brown shaded box); Chocolate, <i>ad libitum</i> access to regular chow, with time limited access to Hershey's Chocolate Chips from ZT4-6 (medium brown shaded box); Chocolate Chips from ZT4-6 (dark brown shaded box) with regular chow replenished daily at ZT12 (green shaded box), in gradually decreasing amounts (green arrowheads denoted reductions, down to 75% of <i>ad libitum</i> intake). (B) Actogram of the one mouse in this group that exhibited anticipatory running to time limited chocolate access. (C) Group mean waveforms of wheel running during <i>ad libitum</i> food access prior to restricted feeding (Base, grey fill, 7-day average), during the last 7 days of time limited access to SlimFast (brown line with circles) and during the last 7 days of access to Chocolate (Choc, heavy brown line). (D) Average waveforms of wheel running from the one mouse that anticipated chocolate access, when this was combined with caloric restriction.
