Figure 1 An example of using the temporal resolution of magnetic stimulation to examine cortical connectivity. This approach is based on the differential effects of high and low intensity stimulation and double coil stimulation. TMS was delivered over MT/V5 to induce the perception of movement and either preceding or following this pulse a single pulse of subthreshold TMS was applied over V1. The results show that the perception of movement was degraded or abolished when V1 stimulation post-dated V5 stimulation by approximately 15–40 milliseconds. (After Pascual-Leone and Walsh, 2001.)
