Web15 de ago. de 2012 · We also observed a typical looming response within 1 s after TOT c. At closer distances, we observed a T90°-associated peak and a decrease in the firing rate after T90° (Fig. 6A, middle and bottom). However, after TOT c at all distances, the firing rate decreased even further, which for 80 and 40 cm distances produced a clear valley. Fig. 6.
