Correlations between actual speed tuning (vertical axis) and different ways of predicting the optimal speed from the spatiotemporal characteristics of the space-time maps. Each pair of connected points corresponds to data for 1 cell. A: optimum speed vs. optimum speed predicted from the ratio of the optimum temporal frequency to optimum spatial frequency. B: optimum speed vs. optimum speed predicted from the space-time slant measured from the slope of the response phase as a function of time. C: optimum speed vs. optimum speed predicted from the peak orientation in temporal frequency/spatial frequency of the Fourier transform of the space-time map.
