Male right handed subjects performed two parallel verbal and nonverbal memory tasks, known to be associated with the anterior temporal lobe, while EEG was recorded from temporal sites referred to either FZ or to linked mastoids. Intrahemispheric coherence and power in the alpha band were calculated. Coherence effects were observed, independent of reference site, which associated the right hemisphere and nonverbal tasks with increased coherence. These effects appear to be relatively specific to more anterior temporal electrode pairs, and confirm previous findings. Power effects demonstrated the difficulty of assessing task-dependent changes independent of reference site, and suggested that specific alpha enhancement may be observed with task involvement. The contribution of coherence analysis to the study of cerebral organisation is discussed.
右利手男性受试者执行了两项平行的言语和非言语记忆任务，已知这些任务与前颞叶相关，同时在参考点为FZ或双侧乳突的颞部记录脑电图。计算了半球内连贯性和α波段功率。观察到连贯性效应，与参考点无关，该效应将右半球和非言语任务与增强的连贯性联系起来。这些效应似乎相对特定于更靠前的颞部电极对，并证实了先前的研究结果。功率效应表明，独立于参考点评估任务相关变化存在困难，并表明任务参与可能会观察到特定的α增强。讨论了连贯性分析对大脑组织研究的贡献。
