Bright-field photomicrographs of adjacent sections of BA9 from a control case. Sections were labeled by immunohistochemistry with an antibody against parvalbumin (A, B) or Nissl-stained (C). In order to provide better visualization of the distribution of parvalbumin-labeled neurons in panel A, black dots were drawn over labeled neurons on the same photomicrograph in panel B. Cortical layers are demarcated in an adjacent Nissl-stained section (C) with black dotted lines. Note that parvalbumin-positive neurons appear in layers II-VI and their density is greatest in layer IV. Roman numerals indicate cortical layers and WM indicates white matter. Scale bar: 200 μm.
