2007 Molecular Psychiatry  
Our data implicate a neural circuit for variation in human personality under genetic control, provide an anatomically consistent mechanism for vmPFC-amygdala interactions underlying this variation, and  ...  We utilized path analysis to parse the effective connectivity within this system, and provide evidence that vmPFC regulates amygdala indirectly by influencing rostral cingulate cortex function.  ...  studying the impact of genetic variation linked to personality on human brain structure and function. 14 In the present paper we pursue this approach, focusing on genetic variation in the X-linked Monoamine  ...

Redefining the endophenotype concept to accommodate transdiagnostic vulnerabilities and etiological complexity

Theodore P Beauchaine, John N Constantino
2017 Biomarkers in Medicine  
Our objectives in writing this essay are to revisit the definition of endophenotype, and to contextualize its current scientific utility in behavioral neuroscience given claims that core assumptions made  ...  Such optimism was spawned in large part by Gottesman and Gould's [3] now famous paper on the promise of endophenotypes.  ...  In addition, poor functional connectivity between the amygdala and the orbitofrontal cortex, and poor top-down control of the amygdala by the medial PFC, are implicated in emotional lability [66] .  ...

An overview is provided of recent twin, molecular genetic, and magnetic resonance imaging studies that are helping to inform a model of developmental vulnerability to adult psychopathy.  ...  One potential implication is that interventions for children with antisocial behavior and callous-unemotional traits may need to be tailored to take into account their distinct pattern of neurocognitive  ...  The authors focused on a hierarchical model of psychopathic personality in which a higher-order general factor substantially explained the variation in the three psychopathic personality dimensions in  ...

Right ventromedial prefrontal cortex: a neuroanatomical correlate of impulse control in boys

Aaron D. Boes, Antoine Bechara, Daniel Tranel, Steve W. Anderson, Lynn Richman, Peg Nopoulos
2008 Social Cognitive and Affective Neuroscience  
Variation in the development of these regions may influence one's propensity for impulsivity and, by extension, one's vulnerability to disorders involving low impulse control (e.g. substance abuse).  ...  Emerging data on the neural mechanisms of impulse control highlight brain regions involved in emotion and decision making, including the ventromedial prefrontal cortex (vmPFC), anterior cingulate cortex  ...  These differences form a core dimension of human personality and behavior that is fairly heritable, emerges early in the course of development and persists across developmental stages (McKay and Halperin  ...

2021 World Psychiatry  
The externalizing superspectrum is one aspect of the general approach to psychopathology offered by HiTOP and can make diagnostic classification more useful in both research and the clinic.  ...  The externalizing superspectrum ranges from normative levels of impulse control and self-assertion, to maladaptive disinhibition and antagonism, to extensive polysubstance involvement and personality psychopathology  ...  This is also borne out by studies that have directly estimated the mag nitude of genetic influences on an externalizing factor, and have found it to be highly heritable 41, 102 .  ...
