To study the neuromodulatory effect of repetitive transcranial magnetic stimulation (rTMS) on perceptual distortion of face (perceived change in size) induced experimentally by local anesthesia.

This study consists of only one session of 2.5-3 hours duration. Changes in the perception of face will be induced experimentally by administering local anesthesia to one side of the face. After which, stimulation will be given using rTMS on the area of ​​the head corresponding to cerebral cortex that controls the sensory function of the face to modulate the perceived changes. The procedure itself is painless and the perceived changes will return back to normal in 1.5- 2 hours.


Participants will receive 150 DKK/hour as a compensation for their time after the completion of experiment.
