The human brain is composed almost exclusively of the [cerebral] cortex. The brain of a chimpanzee, for example, also has a cortex, but in far smaller proportions. The cortex allows us to think, to remember, to imagine. Essentially, we are human beings by virtue of our cortex.

The Cerebral Cortex is the surface region of the brain that is most strongly linked to intelligence. A human’s cerebral cortex, if flattened, would cover four pages of typing paper; a chimpanzee’s would cover only one page; and a rat’s would cover a postage stamp.

If chimpanzees can experience loneliness and mental anguish, it becomes more wrong to use them for experiments in which they are isolated and anticipate daily pain.
