高半球间脑电图相关性（INTERr）或一致性已被解释为胼胝体互连的结果。 脑电图的胼胝体切开术（前三分之二）32岁。老年患者在放松的清醒状态下闭眼记录。 100 2秒将无伪影的时期数字滤波到传统的宽带中，并通过Pearson积矩系数计算INTERr。 前区之间的INTERr，他们应该是预期的，显示该患者的数据和两个对照组的健康人之间的差异非常小。 胼胝体完整的后部区域之间仅观察到少数差异。 这些结果表明，胼胝体的作用是不是至关重要的INTERr和皮质下的影响和半球之间的功能分化可能是更合理的解释INTERr。
High interhemispheric EEG correlation (INTERr) or coherence has been interpreted as a consequence of callosal interconnections. The EEG of a callosotomized (two anterior thirds) 32-yr.-old patient was recorded during relaxed wakefulness with eyes closed. 100 2-sec. artifact-free epochs were digitally filtered into traditional broad bands and INTERr was calculated by means of Pearson product-moment coefficients. INTERr between anterior regions, where they should be expected, showed very few differences between data of this patient and those of two control groups of healthy persons. Only a few differences were observed between posterior regions where the callosum was intact. These results suggest that the role of the callosum is not crucial for INTERr and that subcortical influences and functional differentiation between hemispheres may be more plausible explanations for INTERr.
