Figure 5. Comparison of the amplitude of the H-reflex between the Control-H and TMSSAS+SAS conditions.
Example of EMG responses evoked in the flexor carpi radialis (FCR) muscle by electrical stimulation of the median nerve (MNS). Four consecutive trials in a single subject are shown in each plot. A, Control-H trials: the MNS was delivered at 200 ms before the go cue. B, TMSSAS+ SAS trials: the MNS was delivered 60 ms after TMS and SAS (during cortical silent period). Note that the latency and the amplitude of H-reflex (H) were similar in both conditions. The inset figures highlight the H-reflex size and shape across trials.
