Primary Outcome Measures
NameTimeMethod
<p>We will use electromyography (EMG) to measure motor-evoked potentials (MEPs)<br /><br>over the first dorsal interosseous (FDI) elicited by TMS applied over M1. Here,<br /><br>MEP peak-to-peak amplitude is our primary outcome measure. </p><br>
Secondary Outcome Measures
NameTimeMethod
<p>Our secondary outcome is establishing the technical feasibility of combining<br /><br>TMS and TUS. Here, we will test the technical operation of the combined TMS-TUS<br /><br>equipment and write a technical report on its operation. </p><br>
