stria terminalis
Acronym: st
The term stria terminalis refers to a predominantly white matter structure of the endbrain defined on the basis of myelin stains. It is the most prominent bundle of fibers that projects from the amydala, largely from the corticomedial nuclear group. It emerges from the amygdala caudally then, bounded medially by the lateral ventrical, it arches upward in a semicircular path following the ventricle and continues anteriorly in the junction of the caudate nucleus with the thalamus. As it reaches the major part of the nucleus of stria terminalis some fibers split into smaller bundles, which project ventrally to the medial preoptic area, the anterior hypothalamic area, and the ventromedial nucleus of the hypothalamus ( Carpenter-1983 ). Other terminal areas include the nucleus accumbens, the olfactory tubercle and, perhaps, the midline nuclear group of the thalamus. Most prominent in the human is the hypothalamic component.The stria terminalis also carries some fibers from the hypothalamus to the amygdala ( Olmos-1990 ).
