Linking novelty seeking and harm avoidance personality traits to cerebellar volumes
TLDR
The present data indicating a cerebellar substrate for some personality traits extend the relationship between personality and brain areas to a structure up to now thought to be involved mainly in motor and cognitive functions, much less in emotional processes and even less in personality individual differences.
Individual differences in personality traits: Perfectionism and the brain structure.
Abstract. During the last decade, an increasing number of studies have used neuroscientific methods to examine the relationships between different personality traits and brain structures. This
Gray Matter Volume of a Region in the Thalamic Pulvinar Is Specifically Associated with Novelty Seeking
TLDR
The results increase the knowledge of the structural neurobiology of personality and indicate that individual differences in novelty seeking reflect the structural differences observed in the brain in an area that is widely and densely connected, in line with the typically domain-general behavioral influence of personality traits on a wide range of affective, perceptual, mnemotic, executive, and other cognitive functions.
Non-overlapping and Inverse Associations Between the Sexes in Structural Brain-Trait Associations
TLDR
An important role for sex is indicated in these brain structure-personality relationships, and implies that sex should not just be added as a covariate of no interest in the structural neurobiology of personality.
Linking an anxiety-related personality trait to brain white matter microstructure: diffusion tensor imaging and harm avoidance.
TLDR
Testing the hypothesis that individuals with high scores on the harm avoidance (HA) subscale of the Temperament and Character Inventory show reduced white matter (WM) structural integrity in distributed brain areas, including corticolimbic pathways involved in emotional processing and reappraisal concluded that structural connectivity modulates anxiety-related aspects of personality.
Cerebellum and Personality Traits
TLDR
In a large sample of healthy subjects of both sexes and differently aged, the macro- and micro-structural variations of the cerebellum were correlated with the scores obtained in the Temperament and Character Inventory (TCI) by Cloninger and Cerebellar volumes were associated positively with Novelty Seeking scores and negatively with Harm Avoidance scores.
Social reward dependence and brain white matter microstructure.
TLDR
The theory that WM fiber tract properties modulate individual differences in social reward processing supports the theory that personality traits rely on the integrity and function of distributed neurocircuitry.

Linking novelty seeking and harm avoidance personality traits to basal ganglia: volumetry and mean diffusivity
TLDR
Findings evidencing some brain-temperament relationships highlight the importance of obtaining macro- and micro-structural measures in relation to individual differences.

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.
Regional cerebral brain metabolism correlates of neuroticism and extraversion
TLDR
This study explored correlates between the personality dimensions neuroticism and extraversion as assessed by the NEO Five‐Factor Inventory (NEO‐FFI) and resting regional cerebral glucose metabolism (rCMRglu) in healthy control subjects and found Neuroticism and Extraversion are associated with activity in insular cortex and orbitofrontal cortex, respectively.
Correlation between Human Personality and Neural Activity in Cerebral Cortex
Personality traits are a variance of behavioral patterns among individuals and may reflect a variance of brain activity, but their neurobiological explanation is still a matter of debate. Cloninger
Relationship between personality trait and regional cerebral glucose metabolism assessed with positron emission tomography
TLDR
Evidence linking each biogenetic temperament dimension with specific brain areas and provides a promising base for future personality research is provided.
Investigating the genetic and environmental structure of Cloninger's personality dimensions in adolescence.
TLDR
This is the first twin study of Cloninger's personality dimensions in adolescence--a period marked by significant physiological and social changes and found moderate heritability estimates for NS, HA and RD ranging from .28 to .36--with no evidence for sex-limitation in those influences.
A multivariate analysis of 59 candidate genes in personality traits: the temperament and character inventory
TLDR
The hypothesis that specific personality traits were associated with specific genes was tested and the involvement of different ratios of functionally related groups of genes, and of different genotypes of the same genes, for different traits was found.
Persistence and brain circuitry
TLDR
It is shown that individual differences in Persistence, a dimensional trait assessed with a seven-factor personality model, may be linked to specific areas in the lateral orbital and medial prefrontal cortex and the ventral striatum and this finding represents a fresh approach to linking normalindividual differences in personality and behavior to specific neuronal structures and subsystems.
Cerebral blood flow and personality: a positron emission tomography study.
TLDR
The findings of the study lend support to the notion that introversion is associated with increased activity in frontal lobe regions and suggest that individual differences in introversion and extraversion are related to differences in a fronto-striato-thalamic circuit.
