Extended Data Fig. 6. Gene expression profile of chemical neurotransmission machineries in N. vectensis and M. leidyi.

a, Expression of gene homologs involved in neurotransmitter production, secretion, and reception across the different cell types of adult N. vectensis and M. leidyi scRNA-seq data^12,27. The normalized expression values (molecules/1,000 UMIs for N. vectensis; molecules/10,000 UMIs for M. leidyi) are scaled by gene with dot size scales from smallest to largest, corresponding to lowest and highest expression, respectively. b, Schematic representations of the different neurotransmitter signaling pathways (glutamate, GABA/glycine, acetylcholine and monoamine).
