FIGURE 1-2 The Human Brain (A) Shown head-on, as oriented within the human skull, are the nearly symmetrical left and right hemispheres of the cerebrum. (B) A cut through the middle of the brain from back to front reveals the right hemispheres of the cerebrum and cerebellum and the right side of the brainstem. The spinal cord (not shown) emerges from the base of the brainstem. Chapter 2 describes the brain’s functional anatomy.
