Question

Quizplus · Accepted Answer

Studies using transcranial magnetic stimulation (TMS) have suggested a close relationship between the areas responsible for language production and mouth movements. TMS applied to the left inferior frontal cortex (Broca's area) of the brain, which is responsible for language production, interferes with the ability to perform mouth movements such as lip pursing, while TMS applied to the primary motor cortex—for hand movement—does not have the same effect. This supports the idea that the area responsible for language production is closely linked to the area responsible for mouth movements.
