Dopamine: Go/No-Go motivation versus switching : Commentary on "Neurobiology of the structure of personality: dopamine, facilitation of incentive motivation, and extraversion"

Oades, Robert D. LSF

Sensitivity to incentive motivation has a formative influence on extraversion. Mesoamygdaloid dopamine (DA) activity may, at one level, act as a micro-gate permitting an incentive to influence behavioral organization - 'Go/No-Go' in this scheme. However data on function elsewhere in the mesocorticolimbic DA system is taken to support this particular function. At another level of analysis, the data in this review by D&C along with that on the rest of the VTA system may fit better with a "switching" function in information processing. This link is supported by correlations between measures of extraversion, learned inattention and overall DA activity. The point is extended to the novelty-seeking feature of the extraverted personality.
