CALRETININ-IMMUNOREACTIVE TERMINALS MAKE SYNAPSES ON CALBINDIN D28K-IMMUNOREACTIVE NEURONS IN THE LATERAL NUCLEUS OF THE HUMAN AMYGDALA

A double-labeling immunohistochemical procedure and correlated light a nd electron microscopy were used to examine if calretinin-immunoreacti ve terminals make synapses on calbindin D28k-positive cells. In the la teral nucleus of the human amygdala, calretinin terminals make symmetr ic-like synapses on the somata and proximal dendrites of calbindin D28 k-labeled cells. Our data provide the first evidence that neurons whic h contain two different calcium-binding proteins from synaptic contact s with each other in the human amygdala. (C) 1998 Elsevier Science B.V .
