Neurophysiological investigations in non-human primates and neuropsychological studies in patients with lesions indicate that the inferotemporal cortex is critically involved in visual object recognition. We have recorded event-related potentials from 31 electrodes in a group of healthy normal individuals performing a modified delayed matching to sample task. We have identified a visual memory potential (VMP) which indexes visual short-term memory in humans. This component of the event-related brain potential occurs as early as 170 msec, is maximal at 240 msec, and is generally located in the temporal region. Both the temporal and spatial characteristics of the VMP in humans are in keeping with single cell studies in monkeys.
对非人类灵长类动物的神经生理学研究以及对有脑损伤患者的神经心理学研究表明，颞下皮质在视觉物体识别中起着关键作用。我们在一组健康正常个体执行改良的延迟样本匹配任务时，从31个电极记录了事件相关电位。我们识别出了一种视觉记忆电位（VMP），它可作为人类视觉短期记忆的指标。这种事件相关脑电位成分最早在170毫秒出现，在240毫秒时达到最大值，并且通常位于颞区。人类VMP的时间和空间特征均与对猴子的单细胞研究结果一致。
