Differences in regional brain volume related to the extraversion–introversion dimension—a voxel based morphometry study
LJ Forsman, Ö de Manzano, A Karabanov… - Neuroscience …, 2012 - Elsevier
Extraverted individuals are sociable, behaviorally active, and happy. We report data from a
voxel based morphometry study investigating, for the first time, if regional volume in gray and
white matter brain regions is related to extraversion. For both gray and white matter, all
correlations between extraversion and regional brain volume were negative, ie the regions
were larger in introverts. Gray matter correlations were found in regions that included the
right prefrontal cortex and the cortex around the right temporo–parietal junction–regions that …
