Considered primarily a cognitive trait.[21]ConscientiousnessScrupulous, meticulous, principled behavior guided or conforming to one's own conscience. Associated with the dorsolateral prefrontal cortex. Anorexics are noted to have higher levels of conscientiousness.[22][23][24]ExtraversionGregarious, outgoing, sociable, projecting one's personality outward. The opposite of extraversion is introversion. Extraversion has shown to share certain genetic markers with substance abuse. Extraversion is associated with various regions of the prefrontal cortex and the amygdala.[25][26][27]AgreeablenessRefers to a compliant, trusting, empathic, sympathetic, friendly and cooperative nature.[28][29][30]Neuroticism"Refers to an individual's tendency to become upset or emotional" (Hans Eysenck) "Neuroticism is the major factor of personality pathology" (Eysenck & Eysenck, 1969). Neuroticism has been linked to serotonin transporter (5-HTT) binding sites in the thalamus: as well as activity in the insular cortex.[31][32][33]Neuroticism also predicts the occurrence of more negative life experiences.
