Largest areas are for body regions used most frequently for tactile orientation and analysis, such as face, forepaw, and forelimb. Somatotopical and visual body-surface representation is upside down in vertebrate brains. Somatosensory-map hand region changes size, if hand exercises more. Body-movement topographic map in front of central fissure aligns with somatosensory map.
