Figure 6.
Control for small movements during canceled trials. Spike density functions for canceled trials (red) and latency-matched no-stop signal trials (black) for the first SSD (left). The neuron is the same pre-SMA neuron as illustrated in Figure 5B. Even when small movements are removed (right), the cancelation time still occurs after the SSRT boundary (dotted line). Conventions are as in Figure 5.
