Document Summary
Sleep is a behavior even if it is not distinguish by movement. The change of consciousness is undeniable, but it should not prevent us from noticing the behavioral changes. Research on human sleep is conducted in a sleep laboratory where the experimenter attach electrodes to: The scalp of the sleeper to monitor the electroencephalogram (eeg) The chin of the sleeper to monitor muscle activity recorded as electromyogram (emg) Around the eyes of the sleeper to monitor the eyes movements recorded as the electro-oculogram (eog) Measures heart rate, respiration and changes in the ability of the kin to conduct electricity. Smooth, regular, medium frequency waves (8-12 hz) When a person is resting quietly, relaxed. Not particularly aroused, excited or engaged in strenuous mental activity. Much more prevalent when the eyes are closed but can occur when eyes are open: beta activity. Shows desynchrony: when many different neural circuits in the brain are actively processing information.
