Sequence of experiments and numbers of animals used in the studies
| Experiment 1 | |||||
| Groups | KC | PRT NMDA | SSC NMDA | DSC NMDA | CON |
| (n) | (16) | (15) | (14) | (14) | (34) |
| Part A | Triazolam or 3 hr novel wheel access beginning at CT6 in DD | ||||
| Part B | Phase response to a 5 hr compound stimulus beginning at CT6 in LL (same animals as in Part A) | ||||
| Part C | General locomotion response to triazolam at CT6 in LL (subsets of four to five animals from each group in Part A) | ||||
| Experiment 2 | |||||
| Groups | DSC NMDA | CON | |||
| (n) | (22) | (18) | |||
| Part A | Phase–response curve to triazolam generated in DD (animals tested with and without triazolam in a crossover design) | ||||
| Part B | Phase response to a 5 hr dark or light compound stimulus in LL (groups divided; half get dark and half get light compound stimulus) | ||||
