The top isn't a mess of food. This is largely dependent on what you cook. Fish skin sometimes gets cooked on, glaze bubbles and chars, oil lights on fire and the top surface chars. Something like shrimp, tomato, or sausage will be fairly clean though, and nothing will cook on to the top.
Impairment of language, usually caused by left hemisphere damage either to Broca's area (impairment speaking) or Wernicke's area (impairing understanding, damage in rear parietal/temporal region in the left hemisphere)
By Kendra Cherry. Updated January 03, 2016. Wernicke's area is the region of the brain that is important for language development. The Wernicke's area is located in the temporal lobe on the left side of the brain and is responsible for the comprehension of speech (Broca's area is related to the production of speech). Language development or usage can be seriously impaired by damage to this area of the brain.
