Figure 1. Characterization of the HA and LA phenotype.

Figure 1

(A) Distribution of ambulatory intrinsic SPA (amb SPAINT) measured for 24 h (N = 166). (B) High Activity (HA) and Low Activity (LA) rats used for ppOX have significant differences in ambulatory SPAINT (W = 144, P < 0.001; HA, N = 18, LA, N = 9). Open circles indicate individual animals. (C) Real time PCR analysis showed that HA rats have higher expression of prepro-orexin mRNA (ppOX) in cLH compared to that in LA rats (t23.10 = 2.73, P = 0.011).
