Figure 4.

Individual neuron tuning curve fits during the cue epoch. The left column shows histograms for the R² values for individual neuron tuning curve fits for FR (top) and FF (bottom). The dotted line with the arrow is at 0.7, the cutoff used to separate neurons that were well fit by a von Mises function. The remaining columns only include data from fits for which R² > 0.7. The middle column shows a histogram of the peaks (FR) or troughs (FF) of the fitted curves as a function of radial distance from the RF (°θ), and the right column shows a histogram of the tuning bandwidths as measured by FWHM (°θ).
