Evidence suggests that anomalies of functional organization in the brain may be present in some psychiatric disorders and that EEG differences between psychiatric patients and appropriate control groups may depend on them. It is therefore of practical importance to develop further ways of examining the association between the EEG and such organization. The change in inter-hemisphere coherence (a measure of EEG synchronicity) in the alpha frequency band when carrying out a task is shown to discriminate a group of II right from II left preferent normal individuals. Since right and left preference is associated with differences in cerebral functional organization, the coherence measure may be a useful way of studying this feature of psychiatric illness.
有证据表明，大脑功能组织异常可能存在于某些精神疾病中，且精神疾病患者与适当对照组之间的脑电图差异可能取决于这些异常。因此，进一步开发研究脑电图与这种组织之间关联的方法具有实际重要性。结果显示，在执行一项任务时，阿尔法频段的半球间相干性（脑电图同步性的一种度量）变化能够区分11名右利手和11名左利手正常个体。由于右利手和左利手与大脑功能组织的差异相关，相干性测量可能是研究精神疾病这一特征的有用方法。
