Hierarchical clustering of SNs and MNs reveals shared expression patterns of Dpr and DIP genes in neurons from the same class. (A) SNs from the same class are clustered together based on their expression pattern of Dpr and DIP genes. For example, most es neurons (gray), all chordotonal neurons (purple), and da neurons fall into distinct clusters. (B) Modulatory MNs (II and III) and type-Is MNs are distinct from the main type-Ib cluster. However, individual type-Ib MNs are not easily distinguished based on their expression of Dpr and DIP genes.
