Abstract

Background: investigated the anatomical features and histological structures of the brain of adult common carp. In addition, these features were compared with those of other types of fish.

Methods: Adult fish (8- 18 M) were collected, their gross anatomical features were inspected; and small specimens from different brain parts were fixed, sectioned, stained, and histologically examined.

Results: In the common carp, the olfactory bulb was round, somewhat tiny, and connected to the telencephalon by a very long, thin olfactory tract. The hemispheres of the telencephalon were located rostrally. Only one median ventral telencephalic ventricle was visible. The torus longitudinalis and torus semi-circularis connect the paired optic lobes that make up the large midbrain dorsally and ventrally, respectively. The Valvula cerebelli protruded forward, whereas the corpus cerebelli was positioned posteriorly. The two vagal lobes encircled the two face lobes of the myelencephalon posteriorly and were intimately linked to one another. Fish telencephalon histology showed a greatly reduced structure consisting of a single layer of linked neurons buried in a large neuropil. Conversely, laminar histological structure was observed in the optic tectum.

Conclusions: The brain of a common carp is similar to that of many other fish in that it is primarily composed of five structures: telencephalon, diencephalon, mesencephalon, metencephalon, and myelencephalon. The anatomical characteristics of the common carp brain include the olfactory bulb, olfactory tract, optic tectum, cerebellum, and facial, and vegal lobes.
