The human mammillary body is typically larger and more rounded compared to that of a sheep, reflecting differences in brain size and complexity. In humans, the mammillary bodies are more prominent and have a more developed structure due to their involvement in higher cognitive functions like memory. In contrast, the sheep's mammillary bodies are smaller and less distinct, aligning with their simpler behavioral and cognitive needs. Additionally, the orientation and connection with surrounding brain structures can vary between species.
The human pons is larger (pons serves as a bridge of communication between cerebellum and cerebrum) The sheep medulla is larger (Medulla controls vital functions (breathing and heart beat))
In a sheep brain, the olfactory bulbs are much larger than in a human brain.http://wiki.answers.com/Q/How_do_the_sizes_of_the_olfactory_bulbs_of_the_sheep_brain_compare_with_those_of_the_human_brain"
98% of the human population can't handle sheep brain!
The gyri is a large octopus tentacle that sneezes when the lollipops are attached to the opposite side of the triangular surface of a pancake and the sulci is a turkey times the number of y chromosomes in a head of lettuce.
The human brain is larger. The positioning of the hind brain is different, due to the erect position of humans. Convolutions are increased in humans (increases surface area). The sheep's brain has a smaller cerebellum (lesser motor control/less complex learned motor behaviors). There is a larger pineal gland in sheep (related to circadian rhythms/seasonal reproduction).
The depth of the fissure creating the cerebral hemisphere in a human brain is larger than that of a sheep. This is due to the fact that the human brain is larger and rounder compared to the elongated brain of the sheep.
Sheep brain corpus callosum compares human corpus callosum in a number of ways. These areas of the brain serve similar functions.
Sheep's brains are similar to human brains in structure and function, both having a cerebral cortex, cerebellum, and brainstem. However, human brains are larger and more complex than sheep brains, with a higher cognitive capacity and ability for advanced problem-solving. Additionally, human brains have a greater degree of specialization and flexibility compared to sheep brains.
When you compare human and sheep brain you observe some profound differences between them. This is because they are differently evolved.

Although not identical, the sheep brain holds many biological similarities to the human brain, much more so than a bird's or fish's, as both are mammals. Since it is considered much more humane to not use an actual human brain for study, brains from preserved sheep are examined by students to draw the composition of the brain and obtain physical experience.
