Consecutive transverse sections of the archerfish telencephalon ranging from anterior to posterior (A–F). Sections are immunostained for tyrosine hydroxylase (TH) with accompanying nuclear (DAPI) counterstain. Stippled lines indicate pallial-subpallial boundary. Note that all dopaminergic cell bodies are within the subpallium. Arabic numerals in brackets indicate the relative distance of sections. Scale bar in (A): 0.1 mm (applies to all panels). See abbreviation list and text for details.
