Conversely, the organum vasculosum maintains efferent projections to the stria medullaris and basal ganglia.

These cells also send fibers through the stria medullaris to the lateral habenular nucleus and mediodorsal thalamic nucleus.

Nerve impulses from the habenular nuclei are transmitted to the septal nuclei via the stria medullaris, which is found on the medial surface of the thalamus.

"stria medullaris" - fibers derived from arcuare nuclei, which emerge from the median sulcus and run transversely across the floor to enter into the inferior cerebellar penducle.

The habenula receives input from the brain via the stria medullaris thalami and outputs to many midbrain areas involved in releasing neuromodulators, such as dopamine, norepinephrine, and serotonin.

Deep brain stimulation of the major afferent bundle (i.e., stria medullaris thalami) of the lateral hebenuala has been used for treatment of depression where it is severe, protracted and therapy-resistant.

The stria medullaris, also known as stria medullaris thalami, is a fiber bundle containing afferent fibers from the septal nuclei, lateral preoptico-hypothalamic region, and anterior thalamic nuclei to the habenula.

The pineal gland is reddish-gray and about the size of a grain of rice (5-8 mm) in humans, located just rostro-dorsal to the superior colliculus and behind and beneath the stria medullaris, between the laterally positioned thalamic bodies.

The epithalamus is a (dorsal) posterior segment of the diencephalon (a segment in the middle of the brain also containing the hypothalamus and the thalamus) which includes the habenula and their interconnecting fibers the habenular commissure, the stria medullaris and the pineal body.

Other fibers from this region project through the stria medullaris to the medial and lateral habenular nuclei, the paratenial and anteromedial nucleus of the thalamus, and through the medial forebrain bundle to the pars posterior of the medial mammillary nucleus.
