Where can I find pictures of the sagittal view of the sheep brain and the human brain? And don't say just type into images because I did that. I need like a diagram not necessarily a picture.

I must say the best diagrams I've seen are in Gray's anatomy. Perhaps also in those days, photographs were not common.

Check if this link gives what you need.

Unfortunately the views you need are lack a little in quality.
