Forebrain > olfactory epithelium
Description
Also known as the nasal placode. The olfactory epithelium contains the cell bodies of olfactory sensory neurons that project axons into the olfactory bulb where they contact mitral cells at olfactory bulb glomeruli. In zebrafish the predominant subtypes are ciliated sensory neurons that have long dendrites and microvillous sensory neurons, which have short dendrites, these cells are placodally derived (Aguillon et al., 2018). A third group of neurons associated with the olfactory epithelium express gonadotropin releasing hormone 3 (Gnrh3), these may be the cell bodies of the terminal nerve cranial nerve 0.
