Representative [³H]citalopram binding in ethanol drinkers and controls. (A) A nissl stain of the non-human primate hippocampus in coronal view with relevant regions and layers labeled. (B) A representative example of hippocampal [³H]citalopram binding in a healthy control. (C) A representative example of hippocampal [³H]citalopram binding following chronic ethanol self-administration. Note that lower binding is visually apparent in the ethanol drinker. Abbreviations: gcl, granule cell layer; mol, molecular layer; pcl, pyramidal cell layer; pol, polymorphic layer; slm, stratum lacunosum moleculare; so, stratum oriens; sr, stratum radiatum.
