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…
To replicate and extend the findings of the recent methylphenidate study in which methylphenidate was found to enhance episodic memory performance; To explore whether this effect of methylphenidate is primarily mediated by its dopaminergic action.
To investigate the effects of galantamine on cognitive impairment and visual hallucinations in Parkinson`s disease, both therapeutic (direct effect) and preventive (protection against an acute increase of dopaminergic medication used by the patient…
