LIMA, Eduardo Maurício Mendes de et al. Systematization of the origin, distribution and territory of the caudal cerebral artery on the surface of the encephalon in cats. Cienc. Rural [online]. 2010, vol.40, n.9, pp.1961-1965. ISSN 0103-8478.  https://doi.org/10.1590/S0103-84782010000900017.

In this study were used 26 brains of adult cats, without sex differentiation and definable race, colored with latex and fixed in formaldehyde aqueous solution. The right and left caudal cerebral arteries were single in 96.1% and 88.4% of the sample, respectively. In 69.2% of the samples on the right side and 80.8% on the left, the caudal cerebral artery fin from the anastomosis behind the caudal branch of the internal carotid artery, with a large contribution, and the basal artery terminal branch. In 88.4% of the samples on the right side and 84.6% on the left, the caudal cerebral artery showed the tectal rostral artery and one caudal branche. The caudal branch forked in two branches that supplied the rostral and caudal colliculis of the quadruplet bodies and formed the choroid plexus of the third ventricle. The tectal rostral artery followed ventrally to the piriform lobe and during his way sent some branches to hippocampus. In the left side, this vessel supplied the dorsal surface of thalamus and contributed to the formation of the choroid plexus of the third ventricle.
