Does a human or sheep brain have more sulci?

What is the most advanced part of the brain?

Why do we dissect sheep brains rather than human brains?
A sheep brain is used to teach about memory and where it takes place because its brain structure and functions are similar to the human brain . ... Through dissections, learn about the cortex, brain cells, and where the three main subdivisions of memory (working, long-term, and skill memory) take place.
