SC3 Transcranial Magnetic Stimulation
Transcranial magnetic stimulation (TMS) is a non-invasive method to manipulate brain activity and therefore an interesting tool to establish causal relationships in cognitive neuroscience. TMS has the power to influence motoric and sensory processing on a level that is perceived by the stimulated individual immediately. In this respect, stimulation of the motor cortex leads to muscle twitches in that part of the body controlled by the specific cortical area. Furthermore, TMS has the ability to modulate the processing of visual perception. One phenomenon evoked by TMS is the so-called phosphene, i.e. optical illusions that appear in the respective representative area of the visual field due to stimulation. In clinical settings TMS is further used to elevate the mood and ease the symptoms of depression, tinnitus or migraine, etc.
This course will give an introduction on the principles of TMS, its applications and its potential to shape sensations at different levels. The course is planned to be closed by practical demonstrations.
