Images of a coronal section through the specimen. A. Blockface image acquired with a Nikon D700 camera (original resolution of 45μm/pixel) immediately before the tissue section was collected; B. The section corresponding to the blockface image, mounted on a large-format (5×7in) glass slide and stained for Nissl substance (Simmons and Swanson, 1993), which allows for the visualization of cell bodies; C. The section adjacent to the blockface image, mounted and stained using a modified Gallyas silver impregnation stain (Gallyas, 1979), which allows for the visualization of myelinated connections between neurons.
