What is the fimbria fornix?
The fornix originates in the hippocampus, where it emerges from a collection of fibers called the fimbria. It then stretches up and around the thalamus toward the front of the brain. When it reaches a tract called the anterior commissure, it branches downward.
What is the Fimbria in the brain?
white matter tract that contains afferent and efferent fibers of the hippocampus. The fimbria travels along the hippocampus; when it separates from the hippocampus it becomes the fornix.
Is the Fimbria part of the fornix?
The fornix, named for its archlike configuration (Figs 1 and 2), is formed from the fimbria, which is the fringelike medial continuation of the alveus that sits on the superior surface of the hippocampus just below the ependymal lining on the floor of the temporal horn of the lateral ventricles (Fig 3).
What is the fornix function?
The fornix is a white matter bundle located in the mesial aspect of the cerebral hemispheres, which connects various nodes of a limbic circuitry and is believed to play a key role in cognition and episodic memory recall.
Is the Fimbria part of the hippocampus?
The hippocampus contains parts like the fimbria, crus, body, and column—the fimbria forms where alveus fibers converge along the medial portion of the lateral ventricle’s inferior horn.
What does the fornix do?
Is the fornix Association fibers?
The fornix (meaning “arch” in Latin) is a C-shaped bundle of nerve fibers in the brain that acts as the major output tract of the hippocampus. The fornix also carries some afferent fibers to the hippocampus from structures in the diencephalon and basal forebrain….Fornix (neuroanatomy)

What information does the fornix carry?
Function. Being the main output tract of the hippocampus, the primary role of the fornix is to transmit the information from the hippocampus to the mammillary bodies and to the anterior nuclei of thalamus.
What does the fornix connect?
The fornix connects: the hippocampus to the mammillary bodies. the hippocampus to the septal nuclei and the nuclei accumbens. the mammillary bodies to the anterior nuclei of the thalamus.

The fornix (meaning “arch” in Latin) is a C-shaped bundle of nerve fibers in the brain that acts as the major output tract of the hippocampus. The fornix also carries some afferent fibers to the hippocampus from structures in the diencephalon and basal forebrain. The fornix is part of the limbic system.
