Time of neuron origin in the anterior olfactory nucleus (AO) and nucleus of the lateral olfactory tract (NTOL) was determined autoradiographically in adult mice which received tritiated thymidine once during development. Each subdivision of AO has an individualized period and pattern of neuron origin. All subdivisions contain neurons which arise on E11; but the medial, dorsal, and external subdivisions complete their complement by E18 whereas posterior and lateral neurons continue to arise through P1. No gradients along the caudorostral axis were discerned. Neurons of NTOL arise early (E10‐14), typical of large neurons and similar to those of the surrounding anterior amygdaloid area.
