The fasciculus retroflexus, also known as the habenulointerpeduncular tract, is a bundle of nerve fibers in the brain. It is part of the epithalamus and connects the habenula to the interpeduncular nucleus.
Structure[edit | edit source]
The fasciculus retroflexus is a slender tract of white matter that originates in the habenula, a small structure located near the thalamus. It descends through the midbrain to reach the interpeduncular nucleus, which is situated between the cerebral peduncles.
Function[edit | edit source]
The fasciculus retroflexus plays a role in the modulation of dopaminergic and serotonergic systems. It is involved in the regulation of mood, reward, and pain. The tract is also implicated in the processing of olfactory information and circadian rhythms.
Clinical significance[edit | edit source]
Damage or dysfunction of the fasciculus retroflexus can be associated with various neurological disorders. It has been studied in relation to depression, schizophrenia, and substance abuse.
