DG GCL granule cell layer of the dentate gyrus, SLM stratum lacunosum moleculare, SGZ subgranular zone, CA cornu ammonis, SO stratum oriens, SP stratum pyramidale. A Representative microscopy of PNNs labeled with WFA in CA1 SO, scalebar = 50 µm. B Inset of Fig. 4A at high-magnification, scalebar = 30 µm. C Representative microscopy of a WFA-labeled glial cell proximal to the DG GCL, scalebar = 50 µm. D Inset of C at ×40 magnification, scalebar = 50 µm. E Comparisons of PNN densities throughout the hippocampus between control (white bars) and monkeys with chronic alcohol self-administration (red bars). F Comparison of WFA-glia densities in the DG GCL and DG SLM between control and monkeys with chronic alcohol self-administration. G Comparison of WFA-glia densities in the SGZ and CA nuclei of the hippocampus between control and monkeys with chronic alcohol self-administration.
