Properties of direction-selective neurons in the SC are unchanged in Fmr1^−/y mice. a, b Polar plots of representative direction-selective (DS) neurons in the SC of Fmr1^+/y (a) and Fmr1^−/y (b) mice. Orientation of the stimulus is represented around the circumference of the plot, and firing rate is indicated by concentric rings increasing centrifugally. c Quantification of the cumulative probability of DS neurons with different preferred directions. d Quantification of the cumulative probability of DS neurons with different preferred spatial frequencies. e Quantification of the tuning width of each DS neuron, bar indicates the mean. f Quantification of the baseline and peak firing rates for individual DS neurons. ****p ≤ 0.0001, Wilcoxon matched-pairs signed rank test
