We investigated psychophysiological responses to fear and anger inductions during real-life and imagination. Female participants (N = 158) were assigned to a fear-treatment, fear-control, anger-treatment, or anger-control group. Context (real-life, imagination) was varied in two sessions of fixed order. Eleven self-report and 29 somatovisceral variables(More)
State effects on frontal alpha electroencephalograph asymmetry (ASY) are thought to reflect approach and withdrawal motivational tendencies. Although this motivational direction model has inspired a large body of research, efforts to disentangle influences of emotion (EMO) and motivational direction (MOT) on ASY are rare. The authors independently(More)
The use of D2/D3 dopaminergic agonists in Parkinson's disease (PD) may lead to pathological gambling. In a placebo-controlled double-blind study in healthy volunteers, we observed riskier choices in a lottery task after administration of the D3 receptor-preferring agonist pramipexole thus mimicking risk-taking behavior in PD. Moreover, we demonstrate(More)
Parkinson's disease (PD) is a neurodegenerative disorder affecting dopaminergic neurons in the substantia nigra leading to dysfunctional cortico-striato-thalamic-cortical loops. In addition to the characteristic motor symptoms, PD patients often show cognitive impairments, affective changes and other non-motor symptoms, suggesting system-wide effects on(More)
Monetary gains and losses in gambling situations are associated with a distinct electroencephalographic signature: in the event-related potentials (ERPs), a mediofrontal feedback-related negativity (FRN) is seen for losses, whereas oscillatory activity shows a burst of in the θ-range for losses and in the β-range for gains. We used whole-head(More)
The neuropeptide arginine vasopressin (AVP) is known to modulate aggressive behavior in mammals, but the neural mechanisms underlying this modulation are not clear yet. In the present study, we administered 20 IU AVP nasally in a randomized, placebo-controlled, double-blind manner to 36 healthy men using a between-subjects design. After drug administration,(More)
The Nucleus accumbens (Nacc) has been proposed to act as a limbic-motor interface. Here, using invasive intraoperative recordings in an awake patient suffering from obsessive-compulsive disease (OCD), we demonstrate that its activity is modulated by the quality of performance of the subject in a choice reaction time task designed to tap action monitoring(More)
The ventral striatum/nucleus accumbens (NAcc) has been implicated in the craving for drugs and alcohol which is a major reason for relapse of addicted people. Craving might be induced by drug-related cues. This suggests that disruption of craving-related neural activity in the NAcc may significantly reduce craving in alcohol-dependent patients. Here we(More)
BACKGROUND The use of self-generated and externally provided information in performance monitoring is reflected by the appearance of error-related and feedback-related negativities (ERN and FRN), respectively. Several authors proposed that ERN and FRN are supported by similar neural mechanisms residing in the anterior cingulate cortex (ACC) and the(More)
