In the present study, we investigated the event-related potentials (ERPs) related to the inhibitory motor control in the index finger movement pushing the force sensor triggered by stop-signals with visual, auditory and somatosensory stimuli. The subject abandoned the voluntary finger push controlled from 0 N to 2 N immediately after the stop-signal. The delay of the stop-signal from the go-signal (stop-signal delay, SSD) was set from 0 ms to 200 ms. Subjects could stop the finger push in 50 ms SSD, while not in 200 ms SSD. In the task with 50 ms SSD, the negative peak followed by the positive peak in ERP was observed at Cz. The topography of the potential showed that the negative component distributed at fronto-central scalp around 200 ms after the stop-signal regardless of the sensory modality of the stop-signal. The positive component around 300-350 ms after the stop-signal distributed in parieto-occipital, midline centro-parietal and contralateral centro-parietal regions with the visual, auditory and somatosensory stop-signals, respectively. However, these positive potential was not observed in the task with 200 ms SSD. The negative component of ERP was supposed to be concerned with the control of the stop-action, and the positive component of ERP was presumed to express the brain activity in the primary sensory area processing the sensory information of the stop-signal as well as the activity in the parietal association area involved in the sensory-motor integration. |
