In this study blood flow was monitored while monolingual right handed subjects read English sentences. Our results confirm the role of the left perisylvian cortex in language processing. However, individual subject analyses reveal a pattern of activation characterized by several, small, limited patches rather than a few large anatomically well-circumscribed centers. Between-subject analyses confirm a later-alized pattern of activation, indicate as active classical language areas such as Broca's, Wernicke's and the angular gyrus, and also point to areas only more recently considered as language-relevant including the anterior portion of the superior temporal lobe and the dorsolateral prefrontal cortex.
