Expression of BDNF mRNA in the human hippocampus. (A) In situ hybridization autoradiograph of a 16 μm coronal section.DG – granular layer of dentate gyrus; Hi – hilar area of dentate gyrus; Sub – subiculum; CA1, CA3 – hippocampal subfields. (B-E) High magnification bright-field photomicrographs of hematoxylin-counterstained neurons in subfields CA1 (B) and CA3 (C), the hilus (D) and granular layer of dentate gyrus (E). Filled arrowhead indicates a neuron with strong labeling, empty arrowhead indicates a neuron with weak or absent labeling and double arrowheads indicate a glial cell showing no labeling.
