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.

The sheep cerebral cortex has around 1.4 billion neurons and humans have 19 billion. There are fewer connection therefore in the sheep's brain than in the human brain. An elephant has a larger brain than a human's but by volume only. A larger animal has a larger brain but not necessarily more neurons. The brain is a computer and the more connections the more computing power.

The fissure depth in the cerebral hemisphere of sheep are relatively smaller compared to the human brain. The human brain also has more convolutions and can carry out more complex tasks.

The human cerebrum has more gyri and sulci than the sheep cerebrum has. Thus, the human cerebrum evolves mental capacity over time but the sheep cerebrum doesn't.
