Cytoarchitecture of the reuniens nucleus. A, Low-power photomicrograph of a coronal section through the rostral thalamus stained for Nissl. B, Photomicrograph of a coronal section stained for Nissl, 1200 µm posterior to A. C–I, Photomicrographs of coronal sections 800 µm posterior to previous image. Dashed line indicates boundaries of RE according to Olszewski (1952). Solid line indicates the midline.
