A monkey is sitting in a tree. For some reason you want to shoot it. But it is an astute (cheeky, even) monkey and will let go of the branch he is swinging from at the same instant you shoot your gun or arrow or blowpipe or whatever weapon you use.. Name the four areas which make up the cerebral cortex of the brain. Describe three ways in which scientists and doctors are able to study the function of parts of the brain. Explain why the case-study of Phineas Gage isn’t the most reliable evidence we have for providing information on brain structure and function. Hecht S, Shlaer S, Pirenne MH. 1942.
