Primary objective:Plasma levels of clonidine, in order to describe pharmacokinetic and pharmacodynamic properties of intravenous clonidine in critically ill ventilated ICU patients.Secondary objectives are: * to evaluate the effect of a 3-hr loading…
The goal of the current investigation is to test the noradrenergic part of a new model that accounts better for results of pharmacological research. This model states that the cholinergic system underlies disengagement, and that the…
We propose to conduct a study in healthy young and elderly subjects and patients diagnosed with mild to moderate AD, FTLD, or DLB where cholinergic and serotonergic challenges are given in a placebo-controlled, crossover fashion. Before each…
We propose to conduct a study in healthy subjects where a serotonergic challenge is given in a placebo-controlled, crossover fashion. Before each challenge, participants will be measured 1 time to define their baseline resting state networks (RSNs)…
The objective of this study is to assess the effects of an increased NE level on the trade-off between exploitation and exploration. More specifically, this study will compare the exploitative/explorative behavior of participants who received either…
To determine the beneficial effect of a single dose of 150 µg clonidine as an adjuvant to chirocaine in retrobulbar block.
The objective of the study is to investigate the effect of alfa2-adrenoceptors on bone turnover.
To determine the feasibility of using ICG to optically guide the surgeon to the SLN of paediatric melanoma and sarcoma patients. The SNP is a diagnostic procedure.
This study aims to clarify whether the brain dopamine and noradrenaline system underlie the electrocortical responses (event-related potentials) that are sensitive to cues signalling reward and probability, the P200 and P300.
