Stria medullaris of thalamus
Stria Medullaris of Thalamus[edit | edit source]
The Stria medullaris of thalamus is a part of the human brain, specifically located in the thalamus. It is a white matter tract that connects the habenula to the septal nuclei and the nucleus accumbens.
Structure[edit | edit source]
The Stria medullaris of thalamus is a narrow white band. It begins in the area of the inter ventricular foramen and extends laterally on the superior surface of the thalamus. It is composed of myelinated fibers that originate from the septal nuclei, the nucleus accumbens, and the preoptic area.
Function[edit | edit source]
The Stria medullaris of thalamus plays a crucial role in the limbic system, which is responsible for emotion, behavior, motivation, long-term memory, and olfaction. It carries fibers from the septal nuclei to the habenula. The habenula then projects to the pineal gland, which is involved in sleep patterns and seasonal cycles.
Clinical Significance[edit | edit source]
Alterations in the Stria medullaris of thalamus have been associated with several neurological and psychiatric disorders, including schizophrenia, bipolar disorder, and depression.
