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)
There are areas of particular importance of the cerebral cortex. The receptive language area, Wernicke's (area 22) area is in the upper temporal lobe, extending back to the supramarginal (area 40) and angular (area 39) gyri. Lesions produce receptive aphasia with problems understanding spoken and written language.
