The effects of intravenous TRH administration on brown adipose tissue activity in healthy, lean men.
To investigate whether BAT tissue can be activated by intravenous administration of TRH. Secondary objectives are to determine whether intravenous TRH increases the degree of cardiovascular sympathetic stimulation and the response of skin…
We hypothesize that perioperative ketamine will reduce cognitive decline in postoperative patients, in line with its analgesic and anti-inflammatory properties. There are no previous data available on the effect of ketamine on postoperative…
Objective: This study will investigate if AIM can be trained among people with chronic anger management processes. According to the AIM model, repeating avoidance responses to threatening stimuli may reduce aggressive impulses within this population…
The objective of this exploratory study is to investigate the acid neutralisation action of sodium alginate oral suspension versus placebo liquid, within the stomach and to assess suitability and robustness of the pH monitoring methodology.
The aim of the study is: to investigate the effect of DCS on the physiological and subjective correlates reflecting conditioned sexual response and subsequent extinction thereof. Hypothesis: We hypothesize that administration of DCS after an…
The current study aims to investigate the effects of catecholamine modulation by methylphenidate during initial stages of consolidation on memory retention and the underlying neural correlates of memory retrieval.
The primary objective of this study is to establish a causal role of the alpha band oscillations in lateralized parieto-occipital areas during spatial updating with whole-body translation using online transcranial alternating current stimulation (…
To enhance learning by entraining theta oscillations in the frontal cortex using transcranial alternating current stimulation
This study will investigate the counter impulse hypothesis. According to the counter-impulse hypothesis, avoidance motivation counters aggressive impulses. Consequently, this regulatory impact should be especially effective when people*s aggressive…
This study aims to investigate the effects of a behavioral intervention which is aimed at the improvementenhancing of parental sensitivity and sensitive disciplinary techniques to on the development of children*s social competence and behavioral…
The main goal of the study is to investigate if small amounts of dopamine could influence engagement during reading, comprehension of the story and vocabulary learning and to investigate if the effect of dopamine is different for carriers of the…
Primary objective:- To identify the psychological mechanisms via which testosterone modulates value-based decision making, such as testosterone's effects on risk-taking levels, impulsivity and self-control in intertemporal choice, and social…
To record all reactions of healthy volunteers induced by the use of a homeopathic medicine and placebo.
1) To determine whether vaccination with yellow fever results in a higher cytokine response upon restimulation in vitro with non-related infectious pathogens, compared to the response before the vaccination.2) To determine whether BCG vaccination…
The study consists of two phases. In the first phase, we aim to investigate whether the dopamine receptor D4 (DRD4) genotype confers differential susceptibility to the effects of early life stress on empathy and prosocial behavior more generally in…
The current study aims to further our understanding of the relationship between baseline measures - such as impulsivity, working memory and social support - and the effects of enhancing dopamine (via methylphenidate administration) across a wide…
We aim to assess the neurocognitive mechanisms of tyrosine supplementation in older adults during different forms of cognitive control depending on the prefrontal cortex: working memory, reactive and proactive response inhibition, and effort…
The properties of CBD, namely potential effects on variables pertaining to fear extinction and potentially on fear retention/reinstatement while having non of the problematic side-effects found in Δ9-THC, make CBD plausibly preferential over Δ9-THC…
To investigate the dynamic relationship between hemodynamic responses to different levels of acute SERT occupancy induced by different doses of the reuptake inhibitor (SSRI) citalopram with 5-HT phMRI, as compared to [123I]FP-CIT SPECT imaging.…
To investigate the effects of conditioning with hydrocortisone on endogenous cortisol. Effects of conditioning on endogenous cortisol in response to a validated short-term psychosocial stress task and other psychophysiological outcomes will also be…
