Cortical Plasticity of the Tactile Mirror System in Borderline Personality Disorder

The cross-modal Paired Associative Stimulation (cm-PAS) will consist of a visual stimulus depicting a hand being touched repeatedly paired with a transcranial magnetic stimulation (TMS) pulse delivered over the right primary somatosensory area, for a total of 150 paired stimuli delivered at a fixed frequency of 0.1 Hz. The time interval between the visual-touch onset and the TMS pulse will be 20 ms for the experimental session and 100 ms for the control session.
