In summary, the collective term 'placodes' refers to some rather different structures, probably with different evolutionary origins. Some sensory placodes (at least the otic and olfactory) may have homologues in basal chordates. Even if this is so, it is apparent that they were elaborated considerably during early vertebrate evolution. Epibranchial and dorsolateral placodes appear to be new; we infer that their origin depended on the evolution of specific inductive signals.[well established][VHOG]
