Where Is Hypothalamic Sulcus?

The hypothalamic sulcus defines the upper border and extends from the interventricular foramen to the cerebral aqueduct, above which lies the thalamus. The anterior border is roughly defined as a line through the anterior commissure, lamina terminalis, and optic chiasm

optic chiasm
The chiasm is anteriorly displaced in approximately 10% of individuals and posteriorly displaced in 15%. Posterior to the optic chiasm, the visual pathway continues into both the right and the left sides of the brain (the structures on only one side are described here).

Where are hypothalamic neurons located?

In their central location in the ventral forebrain (Fig. 1A,B), hypothalamic neurons are positioned to sense both neural and physiological signals and to respond by releasing neurotransmitters and peptide neuromodulators into the brain.

Where is the hypothalamus located anatomically?

Hypothalamus is located just below the thalamus and forms the floor and the lower part of the lateral walls of the third ventricle. Anteriorly, it extends up to the optic chiasma and posteriorly it is continuous with the tegmentum of midbrain.
