Primary Outcome Measures
NameTimeMethod
<p>- Cortical inhibition as reflected by SICI using a conditioning pulse with<br /><br>60%RMT intensity<br /><br>- Cortical plasticity as reflected by iTBS induced increase of MEP*s over the<br /><br>time course of 20 minutes after plasticity induction.</p><br>
Secondary Outcome Measures
NameTimeMethod
<p>- To determine the difference in motor skill learning between NF1 patients and<br /><br>unaffected controls.<br /><br>- To determine the correlation between cortical inhibition and motor<br /><br>skill learning<br /><br>- To determine the correlation between cortical plasticity and motor skill<br /><br>learning<br /><br>- To determine the correlation between cortical inhibition and cortical<br /><br>plasticity<br /><br>- To determine whether there is a difference in cortical inhibition as<br /><br>measured by the SICI (80%) TMS paradigm between adults with NF1 and unaffected<br /><br>controls<br /><br>- To determine whether there is a difference in cortical inhibition measured by<br /><br>the CSP TMS paradigm between adults with NF1 and unaffected controls. </p><br>
