最近对分离综合征传统观点的挑战主要是基于连合切开术患者大脑半球之间共享信息的证据。和N.G.西海岸系列为了评估这些主张的普遍性，患者J.W.，副总统和副总统使用一系列实验进行了测试，这些实验复制并扩展了在西海岸系列中进行的一些实验。使用数字身份和价值的比较作为模型任务，我们没有发现任何迹象表明J.W.或D.R.可以分享他们执行的任何任务的信息。副总裁，在以前的研究中，他没有留下胼胝体纤维，并且表现出高度特异性的转移，在田间条件之间的三分之一中表现出高于机会（60%）。总之，这些数据无法支持裂脑患者表现出统一认知功能的证据，特别是在更抽象、非知觉的任务中。这些数据与胼胝体作为主要的半球间通路的传统观点是一致的，通过这种通路，感觉和高水平的认知整合得以实现。
Recent challenges to the traditional view of the disconnection syndrome have been based primarily on evidence of information shared between the hemispheres in commissurotomy patients L.B. and N.G. of the West Coast series. In order to evaluate the generality of these claims, patients J.W., V.P. and D.R. were tested using a series of experiments which replicated and extended some of the experiments carried out in the West Coast series. Using comparisons of numerical identity and value as the model tasks, we found no indication that the separated hemispheres of J.W. or D.R. could share information on any of the tasks they performed. V.P., who has spared callosal fibres and has shown highly specific transfer in previous investigations, performed above chance (60%) in one out of three between field conditions. Together the data fail to support the claims that split-brain patients show evidence of unified cognitive functioning particularly for more abstract, nonperceptual tasks. The data are consistent with the traditional view of the corpus callosum as the primary interhemispheric pathway by which sensory and high-level cognitive integration is achieved.
