“…The location and extent of the hippocampal fissure is thus different for primate and nonprimate species in the sense that the hippocampal fissure is contained within the temporal lobe only in primates, while it continues under the corpus callosum in the remainder of the mammalian species. Mammals such as giraffe, bison, and elephant (Lauer, 1963) and cat (Room and Groenewegen, 1986) have a larger temporal extension of the hippocampus and hippocampal fissure than other species, but a noticeable portion of the hippocampus is still directly under the corpus callosum.…”

“…In nonhuman primates the uncus has a rounded appearance with no other gross morphologic details. The uncus as a prominence of the most rostral portion of the hippocampus is absent in most mammal species (although it has been reported in the dolphin by Jacobs et al, 1979, and in the elephant by Lauer, 1963). However, the uncus can be considered a distinctive feature of primates.…”

The macroscopic anatomy of the brain of the American Plains Buffalo (Bison bison bison) is detailed herein for the first time. Many features vary significantly from most previously described ungulate species including its large size, fissural pattern of the cerebral hemispheres and well developed insular cortex. The midbrain, particularly the tectum, is outstanding: the superior colliculi appear to be the largest reported for any mammal and occupy most of the dorsal midbrain by surface area and volume estimates. The cerebellum is small relative to the total brain volume, a peculiarity reported elsewhere for other ungulates. Morphometric criteria further indicate the brain of bison is highly specialized. Drawing from various lines of evidence, it is suggested that the anatomical uniqueness of the present day bison brain may represent a vestige of the past, remaining largely unchanged over a broad expanse of geologic time.
