Description of part

This column is composed of homogeneous, densely packed, darkly stained, round to oval neurons, located in the extreme medial aspect of the posterior part of the medial bed nucleus (Figs. 15D, l6A, 27 A, and 27B). The small-celled column extends ventromedially and stops at a level adjacent to the posterodorsal preoptic nucleus. In the ventral part of the small-celled column, the densely packed cells form an oval cylinder in horizontal sections (Fig. 28A), whereas dorsally this column is larger and more round. The cells in the dorsal subventricular portion of this column expand to form a wider head, which appears to be partially encapsulated by a cell-poor zone of fibers. These cells are more loosely packed and even more homogeneous in appearance than those in the deeper portions of this column, where larger cells are sometimes intermixed with the predominantly small-cell population. The cells in the dorsal part of the small-celled column lie adjacent to the accessory olfactory tract as it separates from the stria terminalis.
