MODULE 13

The HYPOTHALAMUS

- - - The position of the hypothalamus within the brain is best seen in mid-sagittal views. The first one (Figure 1-40) relates the hypothalamus to other regions, and the next (Figure 13-7) defines the borders of the diencephalon (of which the hypothalamus is a part). The following view (Figure 13-8) reminds us that the third ventricle separates the region into two halves and the last one (Figure 13-9) shows how the hypothalamic sulcus forms a border between the thalamus and the hypothalamus. Blumenfeld describes the hypothalamus on pages 740-742. His Figure 17.3 is useful and the drawings in his Figure 17.4 are remarkably similar to our slides 31-39, called up below. However, our aim in this module is simply to make certain you know where this region of the brain is. On the slides we have marked in most of the nuclei, but we do not expect you to be able to identify them.
