Figure Lengend Snippet: Representative hippocampal regions of interests. (A) Regions of interests sampled for [ 3 H]Ro15-4513 and [ 3 H]flumazenil. (B) Regions of interests sampled for [ 3 H]UCB-J. dHip CA1: dorsal hippocampus CA1; mHip CA3: middle hippocampus CA3; mHip CA1/2: middle hippocampus CA1/CA2; vHip CA3: ventral hippocampus CA3; dHip DG: dorsal hippocampus dentate gyrus; mHip DG: middle hippocampus dentate gyrus.

Article Snippet: To quantify density of α5GABA A R – sections were incubated for 60 minutes at room temperature in 2nM [ 3 H]Ro15-4513 (Perkin Elmer, NET925250UC), or in 2nM [ 3 H]Ro15-4513 with 10 µM bretazenil (Sigma, B6434) for nonspecific binding.

Figure Lengend Snippet: [ 3 H]UCB-J, but not [ 3 H]Ro15-4513 or [ 3 H]flumazenil binding in Lhx6-Cre;Erbb4 F/F mice is decreased across the hippocampus. (A) [ 3 H]UCB-J showed a significant decrease in synaptic density in Lhx6-Cre;Erbb4 F/F mice (n=11) compared to control animals (n=9) across all hippocampal ROIs (mixed effects analysis; main effect of genotype: F (1,18) =7.27, p =0.02, ). (B) [ 3 H]Ro15-4513 (n=10-11/group) and (C) [ 3 H]flumazenil (n=9-10/group) binding did not differ by genotype. dHip CA1: dorsal hippocampus CA1; mHip CA3: middle hippocampus CA3; mHip CA1/2: middle hippocampus CA1/CA2; vHip CA3: ventral hippocampus CA3; dHip DG: dorsal hippocampus dentate gyrus; mHip DG: dentate gyrus.
