Localization of D2 receptors in terminals presynaptic to CB1-labeled dendrites. A: Acb core, processed for D2-peroxidase and CB1-gold. D2 receptor immunoperoxidase (block arrow) is present in an axon terminal (D2-t) forming a symmetric synapse (double curved arrows) with a dendrite that shows CB1 immunogold (thin arrows) in both the dendritic shaft (CB1-d) and spine (CB1-s). B: Acb shell, processed for D2-peroxidase and CB1-gold. Peroxidase immunoreactivity is seen throughout a small terminal (D2-t) forming a punctuate synapse with a dendrite (CB1-d) in which the CB1 immunogold-silver particles (small arrows) are located within and near the synapse. Scale bars = 0.5 μm.
