Subjects performed word-stem completion and produced either novel or repeated (primed) words across trials. Activation passes from primary visual cortex (activated at \~{}100 msec after word presentation), to left anteroventral occipital (\~{}180 msec), to cortex in and near Wernicke{\textquoteright}s (\~{}210 msec) and then Broca{\textquoteright}s (\~{}370 msec) areas. In addition, a posteroventral temporal area is activated simultaneously with posterosuperior temporal cortex. This area shows an early (\~{}200{\textendash}245 msec) increase in activation to repeated word stems. In contrast, prefrontal and anterior temporal regions showed activity reductions to repeated word stems late (\~{}365{\textendash}500 msec) in processing. These results tend to support classical models of language and suggest that an effect of direct item repetition is to allow word-form processing to increase its contribution to task performance while concurrently allowing reductions in time-consuming frontal temporal processing.}, issn = {0270-6474}, URL = {https://www.jneurosci.org/content/21/10/3564}, eprint = {https://www.jneurosci.org/content/21/10/3564.full.pdf}, journal = {Journal of Neuroscience} }
