Fig. 6: Saliency-encoding neurons are less selective to orientation and motion direction.
From: Preference-independent saliency map in the mouse superior colliculus
a Upper panels: orientation map and direction map represented by excitatory and inhibitory neurons in an example imaging plane. The length of lines or arrows is proportional to gOSI or gDSI. Lower panels: saliency maps measured by SFGs and SMGs in the same plane. b Box plots for the absolute difference in SI of neuron pairs versus their horizontal distance. Black dashed lines indicate the separation at 75% of the maximum. SFG_Exc: 85 μm, N = 167834 neuron pairs; SFG_Inh: 75 μm, N = 400335 neuron pairs; SMG_Exc: 155 μm, N = 167834 neuron pairs; SMG_Inh: 125 μm, N = 400335 neuron pairs. c SI is negatively correlated with gOSI measured by flashing gratings: r is Pearson’s correlation coefficient, p < 0.001 for all panels. Top inset: histograms of gOSI for neurons with SI < 0 and SI ≥ 0. Right inset: histograms of SI for neurons with gOSI < 0.25 and gOSI ≥ 0.25. d SI is negatively correlated with gDSI measured by moving gratings: p < 0.001 for all panels. Top inset: histograms of gDSI for neurons with SI < 0 and SI ≥ 0. Right inset: histograms of SI for neurons with gDSI < 0.15 and gDSI ≥ 0.15.
