Extended Data Fig. 2. Taxonomies of M1 cell types in humans, marmosets and mice.

a–c, Taxonomies are reproduced from Fig. 1. Leaves are labelled with species-specific clusters, and branches are labelled with major subclasses of neuronal types. We defined 127 human clusters on the basis of Cv3 and SSv4 data, 94 marmoset clusters from Cv3 data, and 116 mouse clusters in a companion paper⁵ by integrating 7 RNA datasets. These apparent differences in cellular diversity are likely to be driven by sampling depth, data quality and statistical criteria. For example, more non-neuronal nuclei were sampled in mice (58,098) and marmosets (21,189) than in humans (4,005), and more non-neuronal types were identified in those species.
