Abstract

PET images of blood flow change that were averaged across individuals were used to identify brain areas related to lexical (single-word) processing. A small number of discrete areas were activated during several task conditions including: modality-specific (auditory or visual) areas activated by passive word input, primary motor and premotor areas during speech output, and yet further areas during tasks making semantic or attentional demands.
