Abstract

An analysis of the relation between sleep postures and EEG power spectrum of young, adult and old male rats was performed. Three postures were distinguished: stretched, curved and curled up. A 5 minutes period of any posture was analyzed. The sleep data were gathered of the first two hours of the sleep period. The analysis revealed that the overall power of a curled up posture was less than that of two other sleep postures. Determination of a relation between an EEG measurement and sleep postures is promising.
