Interventions and Outcome Measures

Arms

experimental: TUMS and Sham Group

During the subjects two visits they will receive a TUMS stimulation and a sham (placebo) stimulation at both visits.

experimental: TUMS or Sham Group

During the subjects first of two visits they will receive either a TUMS stimulation or a sham (placebo) stimulation and at the second visit they will receive the other.

Interventions

Transcranial Ultrasound Magnetic Stimulation

Transcranial Ultrasound Magnetic Stimulation is a paradigm that allows for concurrent and concentric ultrasound stimulation with transcranial magnetic stimulation (TMS).

Primary outcome measure

  • Change in Motor Evoked Potential Amplitude [ Time Frame: baseline and immediately following the TUMS stimulation ]
