Asymmetry of Chimpanzee Planum Temporale: Humanlike Pattern of Wernicke's Brain Language Area Homolog

摘要

The anatomic pattern and left hemisphere size predominance of the planum temporale, a langumage area of the human brain, are also present in chimpanzees (Pan troglodytes). The left planum temporale was significantly larger in 94 percent (17 to 18) of chimpanzee Brains examined.
