Genetic and environmental correlation between personality traits and whole brain summaries of surface area and cortical thickness.

Global thickness Total surface area
Agreeableness ρe = 0.07, p = ns; ρg = −0.04, p = ns ρe = −0.07, p = ns; ρg = 0.08, p = ns
Conscientiousness ρe = −0.02, p = ns; ρg = 0.04, p = ns ρe = 0.04, p = ns; ρg = −0.12, p < 0.05
Extraversion ρe = −0.01, p = ns; ρg = 0.06, p = ns ρe = 0.03, p = ns; ρg = 0.03, p = ns
Neuroticism ρe = 0.11, p = ns; ρg = 0.02, p = ns ρe = −0.09, p = ns; ρg = −0.06, p = ns
Openness ρe = −0.05, p = ns; ρg = −0.02, p = ns ρe = 0.18, p < 0.03; ρg = 0.08, p = ns

Genetic and environmental correlations are computed in the HCP sample, and exact p-values are reported, associations that showed phenotypic correlation at p < 0.05 threshold are in bold.
