Supplementary Figure 3: Proportion of orientation selective LGN axons and V1 neurons.

Histograms of proportion of orientation selective LGN boutons in layer 1 (a, n = 123 images from 37 mice), 2/3 (b, n = 97 images from 36 mice) and 4 (c, n = 98 images from 30 mice) and V1 neurons in layer 2/3 (d, n = 26 volume images from 14 mice) and 4 (e, n = 14 volume images from 10 mice) were shown (see Online Methods for criteria). Proportion of orientation selective LGN axons in layer 4 (c) was significantly lower than those in layers 1 and 2/3 LGN axons (a, b) and V1 neurons (d, e) (p < 0.001, Mann-Whitney U-test with Bonferroni correction).
