Supplementary Figure 8: ACA interneurons (Pval+, Sst+ and Vip+) are innervated by VIS, PTLp and RSP.

(a) Left, viral injection sites in ACA (red box in coronal diagram) of Pvalb-Cre, Sst-Cre and Vip-Cre mice (scale bar, 200 μm). Inset, enlarged view of the region in white box showing starter cells (yellow; scale bar, 20 μm). Right, fluorescence images of VIS, PTLp and RSP (red box in coronal diagram) showing RV-labeled input neurons (green) to each subtype of interneurons in ACA (scale bar, 200 μm). Green, EGFP; red, mCherry; blue, DAPI. (b) Percentages of retrogradely labeled input neurons in selected cortical and subcortical brain regions (n = 3 mice in each group). Each circle represents one mouse. Included are the same structures as in Fig. 2h.
