Extended Data Fig. 5: Posterior forebrain, midbrain, and hindbrain neurons.
From: A lamprey neural cell type atlas illuminates the origins of the vertebrate brain
a, Subtree from the dendrogram of Fig. 1c displaying the expression of selected marker genes for each cell type (gene names mentioned in main text are highlighted in bold). SC, spinal cord. b, Sagittal section (anterior end to the left) of a larval head (white dashed line outlines the brain) showing the expression of SLC6A5, HOXA/B5, and PKD2L1. Dashed lines separate the main brain regions. c, UMAP projection of a larval hindbrain dataset showing the expression of CHAT and TBX6/20. d-m Sagittal sections (anterior end to the left) of the adult brain showing the expression of selected marker genes. Arrows in d and e indicate the putative ___location of cranial nerve nuclei. See Supplementary Fig. 2 for the ISS section schemes; scale bars, 500 μm.
