Immunostaining of NR1 in hippocampus in hAGS and ibeAGS brain. Left panel is from ibeAGS and right panel is from hAGS: (a and b) low power of hippocampus; (c and d) CA1; (e and f) dentate gyrus and hilus; (g and h) CA3. Or, stratum oriens; Py, stratum pyramidale; Ra, stratum radiatum; LM, stratum lacunosum-moleculare; Mo, stratum moleculare; Gr, stratum granulare. Arrowhead indicates the stratum lucidum of CA3 region. Hi, hilus of dentate gyrus. Scale bar in (a) and (b), 500 μm; and in (c–h), 50 μm.
