Group effect for PMv-TMS₅₀ for aperture (top) and rate of aperture closure (bottom) in the PERT condition. A significant increase in aperture closure rate at 200 ms (bottom, first asterisk) led to a modulation in aperture closure that persisted through the 250–600 ms interval (top). Consequently, the rate of aperture closure slowed toward the end of the movement in the TMS condition (bottom, last two asterisks) to prevent overclosing before object contact. All designations are as in Figure 2.
