Study Summary
This study will investigate the test-retest reliability of transcranial magnetic stimulation (TMS) -evoked potentials (TEPs) as measured by electroencephalography (EEG), using three different TMS protocols over five different brain regions in healthy volunteers. The goal is to compare the test-retest reliability of single pulse, inhibitory and excitatory TMS protocols as well as two distinct targeting approaches. The main questions to answer are: 1. This study will investigate whether the test-retest reliability of TEPs differ across TMS protocols. 2. This study will investigate whether the test-retest reliability of TEPs differ between individualized and non-individualized targeting approaches.
Primary Outcome
TMS evoked potentials (TEP) during single and paired-pulse protocols will be measured by simultaneous EEG recording. TEP amplitudes at approximately 40, 60, 100 and 200 ms will be calculated per subject, individualized brain region (anatomically based M1, connectivity based DLPFC and angular gyrus), TMS protocol and session. ICCs will be calculated across sessions and subjects per TEP for each individualized brain region and TMS protocol. ICCs per brain region will be compared between single and
