Openness: Openness to experience, also known simply as openness, is a personality trait that is characterized by a willingness to try new things, a curiosity about the world, and an appreciation for beauty and aesthetics. People who are high in openness are often creative and imaginative, and they enjoy learning new things. See also Personality, Personality traits.

Neurobiology on Openness - Dictionary of Arguments

Corr I 336
Intelligence/Openness/Neurobiology: Openness/Intellect is the only Big Five trait consistently positively associated with intelligence, and one study found it to be the only Big Five trait associated with performance on a battery of working memory and cognitive control tests (DeYoung, Peterson and Higgins 2005)(1), all of which had been validated through neuroimaging and brain lesion studies as indices of dorsolateral prefrontal cortical function.

Dopamine may be involved in Openness/Intellect (DeYoung, Peterson and Higgins 2005(1); Harris, Wright, Hayward et al. 2005(2)); dopamine strongly modulates the function of lateral prefrontal cortex (Arnsten and Robbins 2002(3)) and has been linked to individual differences in fluid intelligence and working memory through genomics, pharmacological manipulation and neuroimaging (e.g., Volkow 1998(4); Mattay, Goldberg, Fera et al. 2003(5)).
Corr I 337
Fluid intelligence and working memory seem to be related primarily to the aspect of Openness/Intellect that can be described as Intellect, whereas crystallized or verbal intelligence is associated not only with Intellect but also with the artistic and contemplative traits that characterize the Openness aspect of the domain (DeYoung, Peterson and Higgins 2005(1); DeYoung, Quilty and Peterson 2007)(6).
