n.
1. a state of alertness and of high responsiveness to stimuli. It is produced by strong motivation, by anxiety, and by a stimulating environment.
2. physiological activation of the cerebral cortex by centres lower in the brain, such as the reticular activating system, resulting in wakefulness and alertness. It is hypothesized that unduly high or low degrees of arousal lead to neuropsychiatric problems, such as narcolepsy and mania.
