Physiology of ArousalPhysiology of Arousal

Arousal levels directly related to autonomic Arousal levels directly related to autonomic nervous system (HR, BP, skin conductivity, nervous system (HR, BP, skin conductivity, and respiration)and respiration)

Two divisions: Sympathetic Two divisions: Sympathetic &Parasympathetic&Parasympathetic
