Experimental procedures and timelines for the pentobarbital-induced sleep test (a) and polysomnographic recordings (b,c) showing typical EEG and EMG waveforms, and FFT spectra in mice. EEG, electroencephalogram; EMG, electromyogram; FFT, fast Fourier transform; REMS, rapid eye movement sleep; NREMS, non-REMS; Wake, wakefulness.
