Arousal is the physiological and psychological state of being awoken or of sense organs stimulated to a point of perception. It involves activation of the ascending reticular activating system (ARAS) in the brain, which mediates wakefulness, the autonomic nervous system, and the endocrine system, leading to increased heart rate and blood pressure and a condition of sensory alertness, desire, mobility, and readiness to respond. WebThe arousal systems also interact, for example, orexins activate noradrenergic neurons in the locus coeruleus (LC) that project to PFC. 40,41 In general, these modulators are released during alert waking and not during deep sleep. 42,43 However, there are striking individual differences, for example, noradrenergic neurons are silent during rapid eye …
