Development of the olfactory system in turbot (Psetta maxima L.)

► Olfactory sensory neurons differentiate sequentially in the turbot epithelium. ► Dividing cells change its location in the sensory organ throughout turbot development. ► Emergence of symmetrical glomerular fields occurs in turbot larvae. ► Glomeruli organization became asymmetric during turbot metamorphosis. ► Olfactory system is not fully differentiated when turbot metamorphosis ends.
