EEG/EMG-based screening of mutagenized mice. (Left) It takes 20–40 min to implant an EEG/EMG electrode in a mouse under isoflurane anesthesia. (Middle) After full recovery from the surgery, the mouse is tethered with a thin and flexible cable to transmit EEG/EMG signals. The tethered mouse can move freely in a cage. (Right) Each epoch of the recorded EEG/EMG is visually scored using a staging-assist software
