Transcranial magnetic stimulation of the primary motor cortex modulates response interference in a flanker task.
In a typical flanker task, responses to a central target ("S" or "N") are modulated by whether the flankers are compatible ("SSSSS") or incompatible ("NNSNN"), with increased reaction times and decreased accuracy on incompatible trials. The role of the motor system in response interference under these conditions remains unclear, however. Here we show that transcranial magnetic stimulation (TMS) of the left primary motor cortex modulates the amount of flanker interference depending on the hand...Expand abstract
