210Healthy Adults Personality Traits And The Amygdala And The Hippocampus In The Volum Of The Related Research

Objective In the nervous science, some studies confirm in normal people with normal personality traits of different brain areas associated, some areas of the brain volume increase and decrease the personality traits are variable has significant contact。 Previous personality traits related to brain structure research focuses on the prefrontal cortex and ventral midline orbital frontal cortex, such as acg to brain areas, rarely on the amygdala and hippocampus。 The purpose of this study is to explore the correlation between personality traits and the volum of the amygdala and the hippocampus.Methods Through the advertising selection recruiting210healthy adults, men107cases, women103cases, age21-60years old, average (39.10±12.20)years old, according to the age distribution will210respondents are divided into four groups。 The big five personality scale is a simplified version (NEO-FFI) and state-trait anxiety scale (STA1) assessment of selected object character, Philips Achieva3.0T magnetic resonance imaging (MRI) scans were used in the research object, to obtain the high resolution three-dimensional brain structural images, volum-based morphometry (VBM) method for the study of the volum of the amygdala and the hippocampus.Results1Trait anxiety and the volume of the amygdala and the hippocampal was negatively correlated in the men of group2.trait anxiety and the volume of the amygdala and the hippocampal was negatively correlated.2Women's neuroticism and the volume of the amygdala and the hippocampal was negatively correlated. Men's neuroticism and the volume of the amygdala and the hippocampal have nocorrelation.3Women's extraversion and the volume of the amygdala and the hippocampal was positive correlated. Men's extraversion and the volume of the amygdala and the hippocampal have no correlation.4Women's openness and the volum of the right hippocampal have positive correlation in the group3,men's openness and the volum of the right amygdala have positive correlation in the group4.5Men's agreeableness and the volume of the amygdala and the hippocampal was positive correlated in the group of1, men's agreeableness and the volume of the amygdala and the hippocampal have positive correlation in the group of3and4.6Women's conscientiousness and the volume of the amygdala and the hippocampal was positive correlated in the group of4,men's conscientiousness and the volume of the amygdala and the hippocampal have no correlation.Conclusions210healthy adults personality traits and the volum of amygdala and the amygdala and the hippocampus all have correlation. The traits and the amygdala and the hippocampus all had significant correlation between sex and age difference.
