Oxytocin receptor immunohistochemistry of the hippocampus. Oxytocin receptor expression was found in the CA1 and CA2 regions of the hippocampus (CA1, CA2) and in the dentate gyrus. a. The left panel demonstrates positive pyramidal neurons in CA1. b. The right panel shows neurons of the dentate gyrus, with oxytocin receptor expression in both the cell soma and the processes
