TLDR
Several personality traits within the Neuroticism and Openness to Experience domain were significantly correlated with blunted DA response to stress, including Angry-Hostility, Vulnerability, and Depression trait.About:

The Links Between Stress and Depression: Psychoneuroendocrinological, Genetic, and Environmental Interactions.
TL;DR: Understanding of the underlying mechanisms that link these factors may contribute significantly to the development of more effective treatments and preventive strategies in the interface between stress and mood disorders.

Poornima Kumar,Poornima Kumar,Lisa H. Berghorst,Lisa D. Nickerson,Sunny J. Dutra,Franziska Goer,Douglas N. Greve,Diego A. Pizzagalli,Diego A. Pizzagalli +8 more
TL;DR: Stress-induced striatal blunting was similar to the profile observed in clinical depression under baseline (no-stress) conditions in prior studies, and offers insight to better understand the etiology of this prevalent disorder.
Journal ArticleDOI
The dopaminergic response to acute stress in health and psychopathology: A systematic review.
TL;DR: The evidence in healthy volunteers (HV) suggests that physiological, but not psychological, stress consistently increases striatal DA release, and stress-related DAergic activity in HV may reflect somatosensory properties of the stressor and readiness for active fight-or-flight behavior.

Dopamine response to psychosocial stress in chronic cannabis users: a PET study with [11C]-+-PHNO.

TL;DR: In conclusion, despite an increase in striatal BPND observed during the control task, chronic cannabis use is not associated with alterations in stress-induced DA release.

GABA levels and TSPO expression in people at clinical high risk for psychosis and healthy volunteers: a PET-MRS study.
Tania Da Silva,Sina Hafizi,Pablo Rusjan,Sylvain Houle,Alan A. Wilson,Ivana Prce,Napapon Sailasuta,Romina Mizrahi +7 more
TL;DR: It is suggested that TSPO expression is negatively associated with GABA+ levels in the prefrontal cortex, independent of disease status, in people at clinical high risk for psychosis and healthy volunteers.

Model Selection and Multimodel Inference: A Practical Information-Theoretic Approach
TL;DR: The second edition of this book is unique in that it focuses on methods for making formal statistical inference from all the models in an a priori set (Multi-Model Inference).
Journal ArticleDOI
Linking "big" personality traits to anxiety, depressive, and substance use disorders: a meta-analysis.
TL;DR: It is found that common mental disorders are strongly linked to personality and have similar trait profiles, and greater attention to these constructs can significantly benefit psychopathology research and clinical practice.
Journal ArticleDOI
Simplified Reference Tissue Model for PET Receptor Studies
TL;DR: The reference tissue model allows for quantification of receptor kinetics without measuring the arterial input function, thus avoiding arterial cannulation and time-consuming metabolite measurements, and for the ligands tested the three-parameter model is a better choice, combining increased convergence rate with increased stability.

Neurobiology of the structure of personality: Dopamine, facilitation of incentive motivation, and extraversion.
Richard A. Depue,Paul F. Collins +1 more
TL;DR: The animal evidence suggests that there are three neurodevelopmental sources of individual differences in dopamine: genetic, “experience-expectant,” and “ experiences-dependent.”
Journal ArticleDOI
MRI-PET Registration with Automated Algorithm
TL;DR: Modifications to this method that allow for cross-modality registration of MRI and PET brain images obtained from a single subject are described and validated quantitatively using data from patients with stereotaxic fiducial markers rigidly fixed in the skull.
