Bed Nucleus Of The Stria Terminalis Intermediate Division

abbreviation: BSTI

Abbreviation

BSTI

Species

Rat

Description of part

The intermediate division of the BST is composed of predominantly angular dark staining (15 microemeters to 20 micrometers) neurons (the largest of all neurons in the BST) which are interposed between the BSTL and posterior BSTM. The cells form a narrow wedge when seen in saggital section, but appear to a flattened crescent in horizontal sections. The ling axes of these cells are oriented in an oblique angle which is parallel to fibers traversing the BSTI in lateroventral to mediodorsal direction. The BSTI extends dorsally until it reaches the dark staining cell groups which accompany the commissural component of the stria terminalis (that is, the bed nucleus of the commissural component of the stria terminalis). Ventrally, the BSTI merges with the lateral preoptic area while laterally it merges with the SLSI.
