Rayleigh plots of peak phases of Per1-luc in SCN (A), lung (B), pineal (C), and salivary (D) from ADX (black circles), sham-operated (gray circles), and ADX animals receiving hydrocortisone treatment (white circles). Details as in Fig. 1. Compared with sham controls, adrenalectomy did not have any effects on phase of SCN, lung, pineal, and salivary glands. Hydrocortisone treatment of ADX animals significantly delayed the phase in lung and advanced the phase in SCN compared with sham controls. Hydrocortisone treatment did not have any effect on the mean phases of salivary or pineal glands of ADX animals. CORT, Hydrocortisone.
