Additional Gene Expression Patterns in the Platynereis Dorsal Brain, Related to Figure 1

(A) Expression of the Giα subunit at 48hpf. Z-projection of a confocal stack, apical view. Red: gene expression; green: axonal scaffold; blue: DAPI.

(B–E) Gene expression in the extended ciliary photoreceptors region (dashed lines, apical views). Expression of the phototransduction cyclic-nucleotide gated channels CNGAα (B) and CNGB (C) at 48hpf; the circadian marker vrille at 48hpf (D) and neuropsin at 72hpf (E).

(F) Expression of MTNR in the developing brain at 48hpf. The arrowheads indicate the ventral cholinergic-MTNR+ neurons.
