Striatal dopamine (D2) receptor availability predicts socially desirable responding.
Research in non-human primates has implicated striatal dopamine (D2) receptor function in the expression of social dominance--a fundamental component of social extraversion. We predicted that trait extraversion - indexed by the revised Eysenck Personality Questionnaire (EPQ-R) - would correlate with striatal DA (D2) receptor measures - indexed by [(11)C]-Raclopride binding potential (BP) - in 2...
متن کاملStriatal dopamine d2/d3 receptor availability is reduced in methamphetamine dependence and is linked to impulsivity.
While methamphetamine addiction has been associated with both impulsivity and striatal dopamine D(2)/D(3) receptor deficits, human studies have not directly linked the latter two entities. We therefore compared methamphetamine-dependent and healthy control subjects using the Barratt Impulsiveness Scale (version 11, BIS-11) and positron emission tomography with [(18)F]fallypride to measure stria...
متن کاملLower striatal dopamine D2/3 receptor availability in obese compared with non-obese subjects
BACKGROUND Obesity is a result of a relative excess in energy intake over energy expenditure. These processes are controlled by genetic, environmental, psychological and biological factors. One of the factors involved in the regulation of food intake and satiety is dopaminergic signalling. A small number of studies have reported that striatal dopamine D2/D3 receptor [D2/3R] availability is lowe...
متن کاملCorrection: Striatal Dopamine D2/3 Receptor Availability in Treatment Resistant Depression
Several studies demonstrated improvement of depressive symptoms in treatment resistant depression (TRD) after administering dopamine agonists which suggest abnormal dopaminergic neurotransmission in TRD. However, the role of dopaminergic signaling through measurement of striatal dopamine D(2/3) receptor (D2/3R) binding has not been investigated in TRD subjects. We used [(123)I]IBZM single photo...
متن کاملThe correlation between striatal dopamine D2/D3 receptor availability and verbal intelligence quotient in healthy volunteers.
BACKGROUND Although a correlation between the central dopaminergic system and intelligence may exist, the results from imaging studies remain inconclusive. The aim of this study was to explore the relationship between striatal dopamine D2/D3 receptor availability and verbal intelligence quotient (VIQ) using single photon emission computed tomography (SPECT). METHOD Striatal D2/D3 receptor ava...
