The connections between the basolateral and central amygdaloid nuclei

With the use of the rapid Golgi method, axons that originate in the basolateral amygdaloid nucleus have been traced directly into the central amygdaloid nucleus in young mouse brains. The axons, which arise from pyramidal cells, have two patterns of collaterals within the central nucleus. In one type, the axon goes through the central nucleus toward the stria terminalis and emits only one or two collaterals. In the second type, the axon enters the central nucleus and gives off a number of thin collaterals, which have many boutons en passant along their course.
