Chronic pain is a debilitating condition and one of the leading causes for patients to seek medical help. Yet it is not completely understood how long-lasting pain manifests in the brain nor are there adequate treatment options to help every sufferer. Previous studies have shown that stimulation with a so-called matrix electrode could lower pain sensitivity by inducing a form of synaptic long-term depression (LTD). On the other hand, the induction of synaptic long-term potentiation-like mechanisms (LTP) could serve as a model of hyperactivation of the pain system which is indicated in chronic pain states. In our study we aim to identify key brain networks after low- and high-frequency matrix electrode stimulation which is thought to induce states of LTD and LTP, respectively. We also want to evaluate whether perception of heat pain lessens after low frequency and whether it becomes more intense after high-frequency stimulation.
Literature review, data analysis, preparation of EEG and fMRI, journal clubs, viewing talks by Senior Researchers, interdisciplinary exchange of information; students have the opportunity to participate in International Research Training Group 2150 - The Neuroscience of Modulating Aggression & Implusivity in Psychopathology
Previous experience with EEG/fMRI is advantageous, but not necessary.
