Arousal System Modulation

Meaning

Arousal System Modulation refers to the precise regulation of the brainstem, thalamic, and cortical networks responsible for maintaining alertness, vigilance, and responsiveness to environmental stimuli. This process involves finely tuning the level of general physiological and psychological activation to be appropriate for the current task or situation. Effective modulation prevents states of hypo-arousal, characterized by sluggishness, and hyper-arousal, characterized by anxiety and over-reactivity. It is the core mechanism of wakefulness and conscious awareness.
