我们通过暂时扰乱该区域的正常功能，研究了后顶叶皮层在时间感知中的参与情况，让受试者对时间或音高做出前瞻性判断。右后顶叶皮质的破坏显着减慢了做出时间判断时的反应速度，但不会减慢音调判断的速度。对左顶叶皮层的类似干扰和对顶点的控制刺激并没有显着改变音高或时间任务的表现。结果表明，时间判断所需的信息处理涉及顶叶皮层，可能是为了优化自愿行动的时空准确性。结果与最近的一项神经影像学研究一致，并就时间处理的心理模型和最近的一项提议进行了讨论，即时间是顶叶皮层系统的一部分，用于编码与动作相关的幅度信息。
We investigated the involvement of the posterior parietal cortex in time perception by temporarily disrupting normal functioning in this region, in subjects making prospective judgements of time or pitch. Disruption of the right posterior parietal cortex significantly slowed reaction times when making time, but not pitch, judgements. Similar interference with the left parietal cortex and control stimulation over the vertex did not significantly change performance on either pitch or time tasks. The results show that the information processing necessary for temporal judgements involves the parietal cortex, probably to optimise spatiotemporal accuracy in voluntary action. The results are in agreement with a recent neuroimaging study and are discussed with regard to a psychological model of temporal processing and a recent proposal that time is part of a parietal cortex system for encoding magnitude information relevant for action.
