在19世纪以前,一直认为大脑两半球不论在功能上或在形态上都是对称的.可是,于1865年Dax及Broca提出“失语症病人的脑部损伤是在左侧大脑半球”这一伟大论断,打破了人类长期以来认为大脑半球对称的想法,从而开创了生物学发展的新纪元.目前,有关大脑半球形态学的非对称性研究集中于颞叶及枕叶的左右差问题.基于这种形态上 Before the 19th century, it was thought that the two hemispheres of the brain were symmetrical both functionally and morphologically. However, in 1865 Dax and Broca proposed that “brain damage in patients with aphasia is in the left hemisphere.” A great thesis, breaking the human thought that the hemispheric symmetry of the brain has long been thought, thus creating a new era of biological development.At present, the asymmetry of the hemispheric morphology of the brain focus on the left and right temporal and temporal occipital problems.According to This form
