Time of Single-Pulse TMS Delivery During Cognitive Task Affects Subject's Reaction Time

In the present study, we investigated the effect of single-pulse TMS on sensorimotor integration (SI). Real and sham TMS was delivered while a subject performed a cognitive task to 6 areas of the cortex responsible for the motor component of SI, 200 ms or 800 ms after the presentation of visual stim...

Summary:In the present study, we investigated the effect of single-pulse TMS on sensorimotor integration (SI). Real and sham TMS was delivered while a subject performed a cognitive task to 6 areas of the cortex responsible for the motor component of SI, 200 ms or 800 ms after the presentation of visual stimuli. Here we show that the time of single-pulse TMS delivery affects the subject's reaction time (RT). RT was significantly slower (p <0.001) when stimulation occurred 800 ms after the presentation of the visual stimuli of the cognitive task regardless of the stimulation type.
