Simultaneous subdural and scalp<scp>EEG</scp>correlates of frontal lobe epileptic sources

Abstract

Not only dorsolateral but also basal and medial sources can be detectable in FLE. This is the first in vivo demonstration derived from simultaneous subdural and scalp EEG recordings of the complementary significance of extensive source activation and higher subdural spike-to-background amplitude ratio in the detection of cortical sources in FLE.
