The Intrahemispheric Localization and Some Electrophysiological Correlates of Language and Memory

  • George A. Ojemann
Part of the Wenner-Gren Center International Symposium Series book series (WGCISS, volume 47)


Issues in the neurobiology of human language involves both lateralization and intrahemispheric organization. Lateralization has been addressed by many of the papers in this volume. Here, we turn to the organization of language within the “dominant” hemisphere. The localization of different language processes there and some electrophysiologic correlates of those processes in the electrocorticogram (ECoG) and single neuronal recordings are discussed.
