| Research Abstract |
Combined measurement of electrocorticography, fMRI, and evaluation of behavioral changes on electrical stimulation in patients with intractable epilepsy revealed consistent functional distribution of language subprocesses with excellent temporal and spatial resolution in areas such as prefrontal, premotor and superior temporal gyri. The present result suggests that electrocorticographic high gamma activity is a reliable marker for local cognitive activity, which will provide useful information on neurosurgical evaluation.
