Question

The focus on neuroscience box, "the neuroscience of personality: brain structure and the big five," described an mri study that investigated whether personality traits are associated with differences in brain structure. researchers found that _____ was associated with larger brain tissue volume in a brain region associated with sensitivity to rewarding stimuli, and _____ was associated with increased volume in a brain region associated with understanding the beliefs of others.

Answer 1

Researchers found that "extraversion" was associated with larger brain tissue volume in a brain region associated with sensitivity to rewarding stimuli, and "agreeableness" was associated with increased volume in a brain region associated with understanding the beliefs of others.

Extraversion was related with bigger cerebrum tissue volume in the average orbitofrontal cortex, a brain region that is related with affectability to remunerating stimuli.

Agreeableness was related with expanded volume in the back cingulate cortex, a cerebrum locale related with understanding the convictions of others; likewise connected with more noteworthy volume in the fusiform gyrus, a zone of the cortex specific for seeing appearances.
