Arousal and Sleep Reticular formation
About sleep • 1.All birds and mammals show characteristic sleep/wake cycles. • 2.sleep is an active state(recorded by EEG) • 3.bottlenose dolphins
Sleep stages Regulatingbyreticular activating system sleep is divided into two broad types: rapid eye movement (REM) non-rapid eye movement (NREM or non-REM) sleep.
Sleep process REM sleep NREM sleep electroencephalography (EEG ) of sleep stages
Cerebrum Brainstem Stimulating For Arousal Regulating Stimulating For Sleep Midbrain Reticular Formation 1.Pon 2.Medulla Melatonin(hormone) produced by pineal gland
Reticular Formation movement Function • 1.maintaining tone, balance, and posture • 2. integrating stimuli motor coordination • 3. gaze centers, central pattern generators • 4. the cardiac and vasomotor centers of the medulla oblongata
Defining signals • 5. pain modulation • 6. habituation • 7. sleep and arousal
