This study investigates the role of the left inferior prefrontal cortex (LIPC) in semantic encoding and repetition priming using functional magnetic resonance imaging (fMRI). Results indicate that semantic encoding is associated with increased LIPC activation, regardless of task difficulty, and that this area shows decreased activation during repeated semantic encoding due to process specificity. The findings suggest that the LIPC functions as part of a semantic executive system that supports the retrieval of semantic information.
