Note: Group comparisons between LMTLE patients, RMTLE patients, and healthy controls were carried out by means of Kruskal-Wallis -test. Significance was set at .
LMTLE: left-sided mesial temporal lobe epilepsy; RMTLE: right-sided mesial temporal lobe epilepsy; Mdn: Median; (*): slightly below cut-off or below the 10th percentile of normative data; (—): not available.
