The fornix (from Latin: fornix, lit. 'arch'; pl.: fornices) 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. While its exact ...
The fornix is a C-shaped bundle of axons that begins in the hippocampal formation of both hemispheres, referred to as the fimbria, and extend through the crus of fornix, also known as the posterior pillars. The fimbria section of the fornix is directly connected to the alveus, which is a portion of the hippocampal formation that arises from the ...
The human brain anatomical regions are ordered following standard neuroanatomy hierarchies. Functional , connective , and developmental regions are listed in parentheses where appropriate. Hindbrain (rhombencephalon)
Hippocampus anatomy describes the physical aspects and properties of the hippocampus, a neural structure in the medial temporal lobe of each cerebral hemisphere of the brain. It has a distinctive, curved shape that has been likened to the sea-horse creature of Greek mythology , and the ram's horns of Amun in Egyptian mythology .
The anterior nuclei receive afferents from the hippocampus and subiculum directly via the fornix, and indirectly via the mammillary bodies and mammillothalamic tract (MTT). They send efferent fibers to the cingulate gyrus, limbic, and orbitofrontal cortex. [1] The anterior nuclei of the thalamus display functions pertaining to memory.

Recently, many studies have been done to analyze the anatomy and function of the Papez circuit. Many scientists have been finding proof that the circuit is related to memory as well as emotion. The limbic system, the modified version of the circuit proposed by MacLean, is thought to be involved in the same functions as well as behavior ...
The subfornical organ (SFO) is one of the circumventricular organs of the brain. [1] [2] Its name comes from its location on the ventral surface of the fornix near the interventricular foramina (foramina of Monro), which interconnect the lateral ventricles and the third ventricle.
