Quizplus · Accepted Answer

Gyri are the large cortical ridges that form the folds in the brain. Sulci are the narrow grooves or fissures between gyri. Pyramids are not found in the cortex, but rather in the medulla oblongata of the brainstem. Commissures are bundles of nerve fibers that connect the two hemispheres of the brain. Lobes are large regions of the brain that are defined by their function and anatomy.
