The superior temporal gyrus (STG) on the left hemisphere has been suggested to be a part of the receptive language systems in human. Here, we determined what brain regions are functionally connected to the superior temporal gyrus, using electrical stimulation via subdural electrodes directly placed on the brain surface. We studied 11 patients with drug-resistant focal epilepsy, who underwent two-stage epilepsy surgery. During extraoperative electrocorticography (ECoG) recording at the bedside, 40 single-pulse electrical stimuli were delivered to a neighboring electrode pairs involving the STG. Stimulation-induced responses were recorded in other regions. The mean amplitude of beta activity was animated on a standard brain template.
