Supplementary Figure 8: Subclassification of excitatory neurons into hippocampal and cortical neuron types.

a. Hierarchical clustering of aggregate single cell data for excitatory neuron cluster and sorted bulk data sets corresponding to different anatomical regions (grey shaded). b. Chromatin accessibility at marker gene loci. c. K-means clustering of promoter distal genomic elements and enrichment analysis for transcription factor motifs. Statistical test for motif enrichment: One-tailed Fisher's Exact test; displayed p-values are Bonferroni corrected for multiple testing⁵⁹.
