Sleep-wake discharge of Orx-positive (Orx+) and Orx-negative (Orx−) Nb-labeled cells

Category of Nb + cells Orx+ Orx− Total

  • Nb-labeled cells were classified individually using ANOVA followed by paired comparisons of average discharge rates (hertz) per major state (aW, SWS, and PS). Those showing state-dependent variation in the discharge rate (p < 0.05) were grouped according to the occurrence of maximal rates during aW (W-max-active), SWS (S-max-active), or PS or aW-PS (P- or WP-max-active). Others were classified as state equivalent (wsp-eq). The frequencies of cell types differ significantly between the Orx+ and Orx− cells (ϰ2 = 10.05; df = 3; p = 0.02).
