Hypothalamic Sulcus [Sulcus Hypothalamicus, Pna, Jna; Sulcus Hypothalamicus (Monroi), Bna; Syn.: Monroe's Fissure, Subthalamic Fissure, Subthalamic Fissure]

The hypothalamic sulcus is a linear depression running along the lateral walls of the third ventricle, separating the medial thalamic surface and the hypothalamus.

The hypothalamic groove starts from the interventricular foramen and ends at the entrance to the cerebral aqueduct, where it connects with the subtubercular groove.

The hypothalamic groove (Sulcus hypothalamicus) is a linear depression located on the lateral walls of the third ventricle of the brain. It separates the medial surface of the thalamus (part of the diencephalon) from the hypothalamus (part of the brain that regulates body temperature, hunger and thirst, and other important body functions).

The hypothalamic groove begins at the interventricular foramen and extends to the entrance to the aqueduct connecting the third and fourth ventricles. It is about 1.5-2 cm long and about 2-3 mm wide.

The function of the hypothalamic sulcus is that it provides a connection between the thalamus and the hypothalamus. This allows the thalamus to receive information about the state of the body and transmit it to the hypothalamus to regulate important functions. In addition, the hypothalamic groove plays an important role in the regulation of body temperature and homeostasis.

Some people may have absent or abnormal development of the hypothalamic sulcus. This can lead to various diseases and dysfunctions of the body, such as impaired regulation of body temperature, metabolic disorders, decreased immunity, etc.

Various methods are used to diagnose hypothalamic disorders, including MRI, CT, electroencephalography, and others. Treatment may include medications, physical therapy, lifestyle changes, and other methods. In some cases, surgery may be required.
