Abstract

<p>Study of the localization of brain language areas started with findings obtained from patients with brain injury, however functional localization studies in epileptology began with findings on brain functional mapping using cortical electrical stimulation during brain surgery.　Knowledge of language area identification and knowledge of language sequelae due to brain resection is essential for those engaged in epilepsy surgery.　In recent years, many non-invasive examination and analysis methods have been developed, and it has become possible to carry out measurements on not only pathological brains such as epilepsy and cerebrovascular disease but also normal brains.　In this educational lecture, I will introduce the language areas related to epilepsy treatment and actual brain functional mapping.　In addition, recent findings on the language areas that are becoming clear by use of various examinations and analysis methods will be discussed, that is, the language areas related to vision, the language areas related to hearing, and the white matter tracts that connect cortical language areas.　These language areas will be discussed together with some cases.</p>
