Using high-resolution magnetic resonance imaging and voxel-based morphometry in 41 healthy individuals, this study evaluated the association between the personality traits of extraversion and neuroticism, on the one hand, and individual differences in localized brain volume and gray matter concentration, on the other, with a special focus on the amygdala. Extraversion was positively correlated with gray matter concentration in the left amygdala, whereas neuroticism was negatively correlated… 
Extraversion Is Linked to Volume of the Orbitofrontal Cortex and Amygdala
TLDR
The present results indicate that the reduced likelihood of developing affective disorders in individuals high on extraversion is related to modulation of emotion processing through the orbitofrontal cortex and the amygdala.
Relationship between Personality and Gray Matter Volume in Healthy Young Adults: A Voxel-Based Morphometric Study
TLDR
It was concluded that brain regions involved in social cognition and affective process accounted for modulation and shaping of personality traits among young individuals.
Volume of left amygdala subregion predicted temperamental trait of harm avoidance in female young subjects. A voxel-based morphometry study
TLDR
The results indicate that the temperamental traits measured using the questionnaire may have a morphological basis in the human brain.
Gender-common and -specific neuroanatomical basis of human anxiety-related personality traits.
TLDR
It is suggested that smaller right hippocampal volume underlies the basis for higher anxiety-related traits common to both genders, whereas anterior prefrontal volume contributes only in females.
Individual differences in trait anxiety are associated with white matter tract integrity in the left temporal lobe in healthy males but not females
TLDR
Self-report data of personality dimensions linked to trait anxiety in the context of white matter tract integrity in the temporal lobes of the human brain are investigated in a large sample of N=110 healthy participants.
Structural correlates of the orbitofrontal cortex and amygdala and personality in female adolescents.
TLDR
These OFC-amygdala structural correlations to personality do not match those reported in adult samples, and multi-modal neuroimaging techniques can help to clarify the underpinnings of personality development between adolescence and adulthood.
Exploring the relationship between personality and regional brain volume in healthy aging
TLDR
The results suggest that personality may not only relate to, but may also moderate age-related cross-sectional decline in prefrontal and medial temporal regions.
Emotional conflict and neuroticism: personality-dependent activation in the amygdala and subgenual anterior cingulate.
TLDR
Using a task that is sensitive to individual differences in the detection of emotional conflict, the authors have provided a neural correlate of the link between neuroticism and anxiety and mood disorders.
Differences in regional brain volume related to the extraversion–introversion dimension—A voxel based morphometry study
TLDR
A voxel based morphometry study investigating, for the first time, if regional volume in gray and white matter brain regions is related to extraversion finds that white matter findings may reflect differences in ascending modulatory projections affecting cortical regions involved in behavioral regulation.
White matter integrity and five-factor personality measures in healthy adults
TLDR
Findings suggest that greater Neuroticism associates with worse integrity of WM interconnecting extensive cortical and subcortical structures including the PFC and amygdala and that greater Openness associates with better integrity ofWM interConnecting extensive cortex and subCortical structure including the dorsolateral PFC.

Negative association of neuroticism with brain volume ratio in healthy humans
TLDR
It is suggested that individual differences in stress reactivity contribute to reductions in brain volume observed during adulthood, after statistically controlling for age and sex.
Association between reduced extraversion and right posterior fusiform gyrus gray matter reduction in chronic schizophrenia.
TLDR
Reduced right posterior fusiform gyrus volume may contribute to disease-related social disturbances, characterized by both low extraversion and reduced sensitivity to human faces.
Mapping brain structure and personality in late adulthood
TLDR
The results suggest that high self-transcendence, which has adaptive advantages in the later part of life, is associated with relatively greater temporal cortical GM volumes.
Enlargement of the amygdala in patients with a first episode of major depression
TLDR
Enlarged amygdala volumes in patients with a first episode of major depression might be due to enhanced blood flow in the amygdala rather than to a neurodevelopmental structural predisposition to major depression.

TLDR
How functional brain imaging, using an individual-differences approach in the processing of emotional stimuli, has begun to reveal the neural basis of extraversion and neuroticism, two traits that are linked to both emotion and health are outlined.
Dispositional pessimism and amygdala activity: a PET study in healthy volunteers
TLDR
Previous neuroimaging findings in healthy subjects indicating a role for the amygdala in transient negative emotional states are extended, and suggest that this multimodal brain region also is involved in more durable negative affects such as dispositional pessimism.
An fMRI study of personality influences on brain reactivity to emotional stimuli.
TLDR
This study provides direct evidence that personality is associated with brain reactivity to emotional stimuli and identifies both common and distinct brain regions where such modulation takes place.
Amygdala core nuclei volumes are decreased in recurrent major depression
TLDR
The volume loss in this closely related structure suggests a shared effect on both structures, potentially glucocorticoid-induced neurotoxicity mediated by the extensive reciprocal glutamatergic connections.
Lack of self-control as assessed by a personality inventory is related to reduced volume of supplementary motor area
TLDR
It was suggested that self-control including self-inhibition is associated with the density of the SMA, the precuneous and the cerebellar vermis, which govern voluntary movements and motor imagery.
Enlarged amygdala volume and reduced hippocampal volume in young women with major depression
TLDR
The results are consistent with previous findings of structural abnormalities of amygdala and hippocampus in subjects with recent-onset major depression and suggest that the size of the amygdala is enlarged in the first years of the disorder, and may decrease with prolonged disorder duration.
