Demographic, Clinical, Neurocognitive & TMS Data

Demographics (n=14)
Age (years) (mean+/−SD)	9.2 +/−2.4
Gender (% male)	71%
Epilepsy Features (n=14)
Seizure Medication Use	50%
Age at First Seizure (years old) (mean+/−SD)	7.2 +/−2.9y
Epilepsy Duration (years) (mean+/−SD)	2.1 +/− 1.4yr
Lifetime Seizures (% with ≤5; % ≤10; % >10)	50%; 21%; 29%
Predominant Spike Side on Diagnostic EEG (Left/Right/Bilateral)	14%; 43%; 43%
Neurocognitive Scores (n=14)
IQ (mean, SD)	103 +/− 13
Inattention (n, %)	5 (42%)
Language Learning (mean z-score, SD)	−0.14 +/− 1.0
Motor Learning (% mean improvement, SD)	12 +/− 16%
Excitability Measurements
rMT(%MSO) (n=14) (median, IQR)	98% [77 to 100%]
Supramaximal rMT(%) (rMT > 100% MSO)	50%
N100 Amplitude (uV) (n=12)	−61 +/− 44
Plasticity Measurements ^***
% MEP Change (n=6) (mean, SD)	+37% +/− 52%
% N100 Change^** (n=9) (mean, SD)	−24 +/− 37%

^**

A negative number indicates that the N100 peak shrinks (approaches zero)

^***

Wilcoxon Rank Sign test showed that the change in motor evoked potential (MEP) and TMS-EEG Evoked Potential (TEP) amplitude were ns (p>0.05).
