Interareal connectivity in the human language system: a cortico-cortical evoked potential study

This study, for the first time, demonstrated that perisylvian and extrasylvian language areas participate in the language system as components of a network by means of feed-forward and feed-back projections. Judging from the CCEP distribution in the posterior language area, a rather broad neuronal network seems to surround the previously recognized core region of this area.
