单细胞活动记录在猕猴颞下皮层执行的任务，需要感知和暂时保留的彩色刺激。许多细胞对刺激的反应不同。通过改变复合刺激的某些特征的相关性，某些细胞对颜色的反应主要取决于任务是否要求动物注意颜色。相当数量的细胞表现出颜色依赖性的差异，放电频率在保留期的任务。差异放电的时间特征以及当不再需要记忆时其溶解表明显示它的细胞参与了保留视觉信息。
Single-cell activity was recorded in the inferotemporal cortex of macaque monkeys performing a task that requires perception and temporary retention of colored stimuli. Many cells reacted differentially to the stimuli. By changing the relevance of certain features of compound stimuli, the reactions of some cells to color depend critically on whether or not the task demands that the animal pay attention to color. A substantial number of cells showed color-dependent differences in frequency of discharge during the retention periods of the task. The temporal characteristics of differential discharge and its dissolution when memory is no longer required indicate that the cells that display it are involved in retaining visual information.
