Summary of the expression pattern analysis of nr4a2, pitx3 and lmx1b genes relative to each THir cluster at 96 hpf stage.

'co-expr.' indicates overlapping expression in the considered area, '-' indicates no overlap, 'adj' indicates TH immunoreactivity and gene expression in adjacent cells but no co-expression.

Abbreviations of the different CA groups: ACL, amacrine cell layer; DC-1/6, diencephalic groups from 1 to 6; LC, locus coeruleus; MO, medulla oblongata; OB, olfactory bulb; PO, preoptic area; Pr, pretectum; SP, subpallium.
