The StartReact Effect on Self-Initiated Movements

Figure 3

Upper part: histogram of the temporal distribution of all EMG latencies for AS trials in bins of 50 ms normalized with respect to the time of startling auditory stimulus (SAS) application, at time 0. Lower part: representative trials from a single subject. ASb: trial before startle. ASc: trial close after SAS. ASl: trial late after startle. OOc: EMG activity recorded from the orbicularis oculi muscle. EMGF: EMG from wrist flexors. EMGE: EMG from wrist extensors. Wrist extension is shown as an upwards change in the angle and velocity traces.
