Extended Data Fig. 3: Cell type composition of all projections.
From: Epigenomic diversity of cortical projection neurons in the mouse brain

a, Joint t-SNE of neurons profiled by epi-retro-seq (n = 6,362) and unbiased snmC-seq2 (n = 15,782, without enrichment of projections) from MOp, SSp, ACA and AI, coloured by subclass (top left), source region (top right), and projection targets in epi-retro-seq (bottom). b, t-SNE of neurons (n = 11,827) projecting to each IT target (top) and ET target (bottom). The cells projecting to the target were coloured by subclass and cells that project to all other targets or whose target was not confidently assigned were greyed. c, The proportion of cells projecting from each source (row) to each target (column) in all subclasses.
