History of childhood adversity is positively associated with ventral striatal dopamine responses to amphetamine
Childhood exposure to severe or chronic trauma is an important risk factor for the later development of adult mental health problems, such as substance abuse. Even in nonclinical samples of healthy adults, per...

Volunteerism and self-selection bias in human positron emission tomography neuroimaging research
Scientists have known for decades that persons who volunteer for behavioral research may be different from those who decline participation and that characteristics differentiating volunteers from non-volunteer...

Genetic association of FKBP5 and CRHR1 with cortisol response to acute psychosocial stress in healthy adults
Chronic dysregulation of hypothalamus–pituitary–adrenal (HPA) axis activity is related to several neuropsychiatric disorders. Studies suggest that cortisol response to stress has a strong genetic etiology, and...

A measure of glucocorticoid load provided by DNA methylation of Fkbp5 in mice
Given the contribution of cortisol dysregulation to neuropsychiatric and metabolic disorders, it is important to be able to accurately compute glucocorticoid burden, a measure of allostatic load. One major pro...

Differences in δ- and μ-Opioid Receptor Blockade Measured by Positron Emission Tomography in Naltrexone-Treated Recently Abstinent Alcohol-Dependent Subjects
Blockade of brain μ-opioid receptor (μ-OR) and δ-opioid receptor (δ-OR) was investigated in recently abstinent alcohol-dependent subjects (N=21) maintained on naltrexone. Subjects completed a 19-day inpatient pro...

Association of Amphetamine-Induced Striatal Dopamine Release and Cortisol Responses to Psychological Stress
Preclinical studies have shown that stress and glucocorticoids increase mesolimbic dopamine (DA) and thereby facilitate psychostimulant self-administration. The relationship between stress-induced cortisol and...

The Mu-Opioid Receptor Polymorphism A118G Predicts Cortisol Responses to Naloxone and Stress
A polymorphism in the mu-opioid receptor (MOR) (A118G) has been shown to increase β-endorphin binding affinity, theoretically placing greater inhibitory tone on hypothalamic corticotropin-releasing hormone (CRH) ...

Article
Relationships Among Ventral Striatal Dopamine Release, Cortisol Secretion, and Subjective Responses to Amphetamine
There is evidence that stress and glucocorticoids alter drug self-administration and mesolimbic dopamine (DA) activity in preclinical models. The primary purpose of this study was to test the hypothesis that g...

Alterations in Hypothalamo-Hypophyseal Function by Ethanol
Alcoholism is a disorder characterized by a persistent and progressive pattern of ethanol ingestion which, over time, results in the loss of control over drinking and a narrowing of interests in activities oth...
