“…The hippocampal formation and its tracts in the fornix bend towards the anterior pole of the diencephalon forming the precommissural (septal) and postcommissural (hypothalamic) connections in relation to the anterior commissure. The fimbria of and fornix constitute a complex system of nerve fibres connecting the hippocampus with other brain structures [1,2,3]. According to recent experimental studies carried out in various species, the fornix is a pathway for afferent and efferent nerve fibres closely connected with the hippocampal formation.…”

The hippocampus is one of the essential brain structures in humans and animals. It belongs to the limbic system and plays an important role in long-term memory and spatial orientation. Many structures of the limbic system of the prosencephalon connect with the hypothalamus through the C-shaped structures (such as hippocampus and fornix) and with the amygdale and terminal stria. The fimbria and fornix of hippocampus form a complex system of afferent and efferent nerve fibres closely related functionally and structurally with the hippocampal formation and other brain parts. The fimbria of hippocampus, which is a broader band of nerve fibres, spreads over the anterior-medial surface of the hippocampal body. The fimbria and crus have been studied in pigs, rabbits, opossums and monkeys. In terms of topography, cytoarhitectonics and morphology, the nerve fibre structures found in foxes/minks are similar to those described in other domestic animals, including the fornix, which is an arched-shaped aggregation of fibres between the hippocampus and mammillary body and the fimbria. The present study was conducted in 5 adult foxes using the Klüver and Barrery method as well as the Landau method modified according to Mirando. Morphological analysis was performed and pictures were taken in the Cell ^ D Soft Imaging System (SIS) combined with a digital camera Colorview IIIu.
