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. Citation, DOI, disclosures and article data. The stria medullaris is a fiber bundle containing efferent fibers from the septal nuclei, lateral preoptico-hypothalamic region, and anterior thalamic nuclei to the habenula. It forms a horizontal ridge on the medial surface of the thalamus.
Thalamus Anatomy, Location, Structure, Function & Physiology
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. Language links are at the top of the page across from the title.

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). 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. Recent literature has implicated the cortico-striatal-pallidal-thalamic loop in the pathophysiology of MDD which implies that stimulation of an afferent white matter tract like the SM modulates a node within a broad network involved in the pathophysiology of mood disorders ( Downar et al., 2016 Identification of the stria medullaris thalami using diffusion tensor imaging Identification of the stria medullaris thalami using diffusion tensor imaging Neuroimage Clin. 2016 Oct 26;12:852-857. doi: 10.1016/j.nicl.2016.10.018. eCollection 2016.

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. The stria medullaris thalami (SM) is the major afferent pathway to the LHb, a small nucleus . located on the dorsomedial surface of the caudal thalamus, adjacent to the third ventricle 11. The
At the time of birth (P0), the cerebral cortex is unformed, but two prominent fibre bundles are apparent in the forebrain: the medial forebrain bundle and the stria medullaris thalami. stria medullaris (redirected from Stria medularis thalami) stria medullaris A thin axon tract that originates in the septal nuclei, the hypothalamus, and the anterior thalamic nucleus and synapses in the habenular nuclei of the epithalamus. It is part of the limbic system. Synonym: stria medullaris thalami See: limbic system for illus
