Before inactivation, a majority (63.5%; 7/11) of area 17 neurons preferred low (<15°/s) velocities (Figure 5C). During inactivation, an upward shift in preferred velocities was observed in two cells (both were complex; Figures 5A–C). Overall however, the mean preferred velocity of area 19 neurons during inactivation at 21.85°/s (±21.65; range: 1.4°–66°/s) was virtually the same as that (19.45 ± 20.95°/s; range: 1.1°–66°/s) before inactivation.
