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)
Language recognition. The temporal lobe holds the primary auditory cortex, which is important for the processing of semantics in both speech and vision in humans. Wernicke's area, which spans the region between temporal and parietal lobes, plays a key role (in tandem with Broca's area in the frontal lobe) in speech comprehension.
