休林斯·杰克逊 (Hughlings Jackson) 22 在 1864 年写道：“如果应该用更广泛的证据证明表达能力存在于一个半球，那么提出知觉的相应对立是否可能不存在于另一半球的问题就不是荒谬的了。” Nielsen 27 于 1937 年证明了一个枕叶相对于另一个枕叶的优势；最近克里奇利讨论了顶叶功能的不对称性。 Sperry 33,34 最近的实验引起了人们对胼胝体功能的新关注，其中包括两个半球不同或互补能力的可能整合。 1938 年的迪德 12 认为两个半球的互补功能是象征性的，而不是知觉性的。然而，越来越多的临床数据积累表明，人类的互补功能可能是语言功能和视觉空间功能。 《Brain》报道了一系列患有右脑肿瘤的患者，他们的视觉定向障碍比其他缺陷更严重。 Heimburger 和 Rei tan 2t 认为，肿瘤可能偏向左侧或右侧，具体取决于患者是否有书写或绘画困难。尽管针对肿瘤患者的定位研究因压力和其他继发症状而臭名昭著，但针对局限性损伤或梗塞患者的研究却提供了支持。例如，Olsen 的 29 名右顶叶血栓患者
H UGHLINGS JACKSON 22 wrote in 1864, " I f , then, it should be proved by wider evidence tha t the facul ty of expression resides in one hemisphere, there is no absurd i ty in raising the question as to whether percep t ioni t s corresponding opp o s i t e m a y not be seated in the o ther ." Nielsen 27 showed in 1937 the dominance of one occipital lobe over the other; and more recently Critchley s discussed a s y m m e t r y in parietal lobe functions. Recent experiments by Sperry 33,34 have drawn new a t tent ion to the functions of the corpus callosum, among them the possible integration of dissimilar or complementa ry capacities of the two hemispheres. Dide 12 in 1938 considered the complemen ta ry functions of the two hemispheres to be symbolic versus gnosokinesthetic. However , an increasing accumulat ion of clinical da ta suggests tha t complem e n t a r y functions in man may be verbal v. visuospatial . Brain ~ repor ted a series of pat ients with r ight cerebral tumors whose visual disorienta t ion disabilities were greater than their o ther defects. Heimburger and Rei tan 2t suggested t ha t tumors might be lateralized to the left or to the right depending on whether the pa t ien t had more difficulty with writ ing or drawing. Although localization studies on t u m o r pa t ien ts are notorious for pressure and o ther secondary symptoms, support has come f rom studies of patients with circumscribed injuries or infarction. Fo r example, Olsen's 29 pa t ien t with a right parietal th rom-
