Effect of IIK7 administration on (A) delta power in the EEG during NREM sleep, (B) theta power during REM sleep, and (C) core body temperature (°C). All epochs scored as NREM (during the first 1 h) or REM (during the first 2 h) after injection of vehicle or IIK7 were analysed using the Fast Fourier Transform function of SleepSign® from 0.5 to 20 Hz. For each rat, delta power (power in the delta range, 1–4 Hz) during NREM sleep and theta power (5–8 Hz) was calculated and expressed as a percentage of total EEG power in all of the NREM or REM epochs analysed, respectively. Mean delta (A) and theta (B) power ± S.E.M. data is shown. (C) Core body temperature was measured for 5 s every 5 min from 20:00 h to 04:00 h. Mean data for each hour of recording was averaged and the mean ± S.E.M. of these values for all 6 rats is shown.
