Comparisons of developmental gene expression suggest that the anterior ectoderm in amphioxus may be homologous to the vertebrate olfactory placode, the only vertebrate placode with primary, not secondary, neurons

The term placode or placodes also applies to developing organs such as teeth, mammary glands, hair follicles, feathers and scales. We include a separate parent class for this. to avoid confusion, we include neurogenic placode as a subclass
