Double immunoperoxidase for BDA and group I mGluRs. The location of injection sites and the receptor subtype the tissue is immunostained for are indicated in the upper right corner of each micrograph. A,B: Electron micrographs of labeled cortical terminals from the dorsal limbic PFC in the core of the nucleus accumbens. C: Cortical terminal from the ventral limbic PFC in the accumbens shell. D,E: Micrographs of labeled terminals from the PVN in contact with mGluR5- (D) or mGluR1a- (E) containing spines in the shell of the nucleus accumbens. F: Example of a terminal arising from the CM/IMD in contact with an unlabeled dendrite in the core of the accumbens. G–I: CM/IMD terminals in contact with labeled or unlabeled spines in mGluR1a–and mGluR5-immunostained accumbens tissue. J,K: BLA terminals in contact with unlabeled and labeled spines in mGluR1a- and mGluR5-immunostained tissue in the core and shell. L: Example of a BLA terminal in contact with an mGluR1a–IR dendrite in the core. Abbreviations: AT, labeled axon terminal; Sp, labeled spine; u. Sp, unlabeled spine; Den, labeled dendrite; u. Den, unlabeled dendrite. Scale bar = 0.2 µm in A-L.
