Fig. 2 ngn1 and neuroD expression reveals the positions of the dorsolateral placodes. Panels show lateral views of zebrafish heads, just posterior to the eye, with anterior left and dorsal up. Neurogenic dorsolateral placodes form at the edges of the otic placode/vesicle, outlined with a dashed line. a, anterior lateral line placode area; ad, anterodorsal lateral line placode/ganglion; av, anteroventral lateral line placode/ganglion; f, facial epibranchial placode/ganglion; g, glossopharyngeal epibranchial placode/ganglion; m, middle lateral line placode/ganglion; nc, neural crest; o, octaval/statoacoustic ganglion precursors; p, posterior lateral line placode/ganglion; t, trigeminal placode/ganglion; v, vagal epibranchial placode/ganglion. Bar, 100 μm.
