Now we are looking at a cross-section of the forebrain of a chimpanzee.

What is the outer groove-like material? What are the inner structures? Does this look different than what you saw in the human forebrain???? What is similar? What is different? Compare with the human forebrain. Are there differences in amounts of cortex? If you remember, the midsagittal views of the five brains showed a relative decrease in cortex. Can you see that difference here in the section slide?

This picture is a good illustration of the cerebral cortex at the frontal lobe of the brain. You can also see the body of the corpus callosum which is the structure connecting the two hemispheres of the brain. The white elliptical openings within the brain are ventricles.

Click on the brain for an even closer look at the cells which make up all of these brain structures. Or click on a button below to learn about these structures or make slices in other animal brains, such as the monkey.

(If you want to see more pictures of cross sections through a chimpanzee brain, go to this site:"Mammalian Brain Collections")

Now, let's slice the cat brain

I want to know more about these structures and their functions

Go back to the sagittal view of the monkey brain

What's the point? On towards magnification

Huh? Can we start over?
