DSCT neurons were recorded during W, AS, and RW in three separate SCs according to Paradigm 1 (Fig. 2; see Materials and Methods). The group mean firing rate (± SEM) in spikes per second of 10 DSCT neurons is presented. The relative change in firing rate during AS or the subsequent episode of RW, compared with preceding episode of W is also presented for each SC. Downward arrows reflect percentage of decrease. Under control conditions, consistent AS-specific suppression occurred from one SC to the next (see AS: SC1–3 vs Wakefulness: SC1–3,

F1-165: p < 0.005, ANOVA).
