An inexpensive sleep-wake state analyzer for the rat.
Manual classification of sleep stages is a tedious and time consuming task. We describe an inexpensive system for sleep-wake state classification for as many as eight rats at a time. It is based on determining threshold values for each parameter of each rat, then finding the natural transitions from one sleep state to another and finally classifying these states utilizing the cortical EEG and EMG signals.
