Abstract
BACKGROUND: Neuropsychological and neuroimaging studies suggest that whereas the left temporal neocortex plays a crucial role in all tasks involving lexical-semantic processing, some regions of the left prefrontal convexity are selectively recruited during verb processing.
OBJECTIVE: To determine if there are different neural correlates for noun and verb processing in the human brain.
METHODS: Repetitive transcranial magnetic stimulation (rTMS), 20 Hz at 90% of the motor threshold, was applied to left or right prefrontal brain during object- and action-naming tasks in nine healthy subjects.
RESULTS: A shortening of naming latency for actions was observed only after stimulation of left prefrontal cortex.
CONCLUSION: The involvement of the left dorsolateral frontal cortex in action naming was demonstrated using rTMS.
