Fig. 10. A reduction in the size of visual cortical regions and an expansion in cortical regions associated with mechanosensory processing are associated with subterranean living. (A) The African hedgehog Atelerix albiventris lives above ground and has well developed visual (V) and auditory processing. (B) The star-nosed mole Condylura cristata is subterranean and has reduced visual (V) representation and an enlarged somatosensory representation. Adapted from Catania (Catania, 2005).
