Abstract

The purpose of the present study was to compare magnetoencephalography
(MEG) data with the results of the intracarotid amytal procedure (IAP).
Twenty-one native Spanish-speaking patients with intractable epilepsy
underwent MEG language mapping. A subset of 8 patients also underwent an
IAP. With the exception of 2 patients who showed right hemisphere
dominance, all other patients showed left hemisphere dominance for
language on the MEG recording. The IAP findings were consistent with MEG
results in 7 patients. The eighth patient who, according to the MEG
data, had probable right hemisphere dominance for language did not show
clear hemispheric specialization for language on the IAP and suffered a
transient global aphasia following a right temporal lobotomy. These
results suggests that MEG-based language mapping can play an important
role in presurgical clinical evaluation.
