WebAutonomic arousal and cortical arousal are essential concepts in Eysenck’s theory of personality because individual differences in these functions are related to the well-known dimensions of emotionality (neuroticism) and extraversion-introversion. WebExtraversion is thought to have a biological basis associated with both cortical arousal and the dopaminergic system. The lower level of cortical arousal and the lower dopaminergic …

WebThe principal neurons of the arousal and sleep circuits are comprised by glutamate and GABA neurons, which are distributed within the reticular core of the brain and, through local and distant projections and interactions, regulate cortical activity and behavior across wake-sleep states. These are in turn modulated by the neuromodulatory ... WebAccording to Eysenck's theory of Introversion-Extroversion (I-E), introverts demonstrate higher levels of basal activity within the reticular-thalamic-cortical loop, yielding higher tonic cortical arousal than Extraverts, who are described conversely as chronically under-aroused and easily bored.
