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 and electron microscopy were used to examine if calretinin-immunoreactive terminals make synapses on calbindin D28k-positive cells. In the lateral nucleus of the human amygdala, calretinin terminals make symmetric-like synapses on...

Description
Summary:A double-labeling immunohistochemical procedure and correlated light and electron microscopy were used to examine if calretinin-immunoreactive terminals make synapses on calbindin D28k-positive cells. In the lateral nucleus of the human amygdala, calretinin terminals make symmetric-like synapses on the somata and proximal dendrites of calbindin D28k-labeled cells. Our data provide the first evidence that neurons which contain two different calcium-binding proteins form synaptic contacts with each other in the human amygdala.
