Supplementary Figure 8: Orientation tuning of thalamic boutons from mice with different GCaMP6s expression levels in lateral posterior thalamic nucleus.
From: Thalamus provides layer 4 of primary visual cortex with orientation- and direction-tuned inputs
(a–c) GCaMP6s expression in visual thalamus of three mice: left to right, decreasing levels of expression in lateral posterior thalamic nucleus. (d–f) Orientation tuning of L1 thalamic boutons measured in vivo from Mouse 1, 2, and 3, respectively: upper left, in vivo image; upper right, boutons color-coded by their preferred orientation; lower left, distribution of preferred orientation; lower right, distribution of tuning width. (g–i) Orientation tuning of L4 thalamic boutons characterized in vivo from Mouse 1, 2, and 3, respectively. Scale bar: 500 μm (a–c), 10 μm (d–i).
