Primary Outcome Measures
NameTimeMethod
Subjects receive thermal heat stimuli during the MRI experiment, which they should assess on a scale of 0 to 100 with regard to their painfulness. Pain ratings are compared between the groups to investigate how remifentanil in combination with the blinded / open application reduces pain perception compared to NaCl.
Secondary Outcome Measures
NameTimeMethod
eural activations are compared between the 3 groups, primarily in pain-processing brain regions and in the spinal cord. In addition, the activation in the descending pain system is examined, as well as the connectivity between these areas.
