The stria medullaris (SM), (Latin, furrow and pith or marrow) is a part of the epithalamus and forms a bilateral white matter tract of the initial segment of the dorsal diencephalic conduction system (DDCS). It contains afferent fibers from the septal nuclei, lateral preoptico- hypothalamic region, and anterior thalamic nuclei to the habenula. The pineal gland, habenular nuclei, and stria medullaris thalami are the principal components of the epithalamus ( Figs. 15.2, 15.4, and 15.15 ). The pineal gland consists of richly vascularized connective tissue containing glial cells and pinealocytes but no true neurons.

This nucleus communicates with the rest of the limbic system via the stria medullaris thalami (along the midline of the roof of the third ventricle). Habenula 1/2. Synonyms: none. In addition to connecting the Habenular nucleus to the hypothalamus, it also connects it to nuclei of the septum (septal area). It is the caudal part of the forebrain (prosencephalon) that occupies the central region of the brain. The diencephalon is comprised of the: Epithalamus Thalamus Subthalamus Metathalamus Hypothalamus In the following article, we will explore the anatomy of different parts of the diencephalon as well as their function.

The habenular nuclei receive afferents via the stria medullaris thalami from the septal area (subcallosal area) and pre-optic nuclei (hypothalamus), via stria terminalis from the amygdaloid body and via fornix from the hippocampus (1, 4-8, 25-28). Some stria medullaris thalami fibers pass through the dorsal lamina of the pineal stalk and. The stria medullaris, also known as stria medullaris thalami, is a fiber bundle containing afferent fibers from the septal nuclei, lateral preoptic hypothalamic region, and anterior thalamic nuclei to the habenula. Pineal Gland. The Stria medullaris (SM) Thalami is a discrete white matter tract that directly connects frontolimbic areas to the habenula, allowing the forebrain to influence midbrain monoaminergic output. Habenular dysfunction has been shown in various neuropsychiatric conditions. The main afferent system is composed by olfactory fibers that run within the stria medullaris thalami. The habenular complex receives these fibers, which are derived from the septal region, hypothalamus, and the amygdala. The stria medullaris thalami is a band of fibers arching on the upper part of the medial surface of the thalamus, passing.

The septal area also projects to the habenula nuclei via the stria medullaris thalami and the anterior hypothalamus. Hypothalamus. The hypothalamus lies at the center of the limbic system and is at the confluence of many neural pathways. It is subdivided from anterior to posterior into three zones: the supraoptic region, the tuberal region and.

Some of those fibers turn backward to enter the stria medullaris thalami and reach the habenular nuclei. Fibers from the dorsal fornix reach the splenial gyrus and the gyrus cinguli; Learn everything about the fornix anatomy and function with our articles, video tutorials, quizzes and labeled diagrams. It lies most medially and adjacent to the AV but is separated from AV, the stria medullaris thalami, and the ventricular surface of myelinated fibers and a glial lamella. Our results show that the.
