当受试者监控视觉呈现的刺激序列时，记录事件相关电位(ERPs)，该序列提供关于时间模式(节奏)和空间模式的信息，并对节奏或空间偏差做出反应。第三项任务需要监测屏幕闪烁的相同序列，作为知觉基线条件，并受控于反应准备效果。对时间和空间顺序信息的监测在不同的地形区引起负慢电位。因此，对同一刺激序列的时间域和空间域的注意被不同的ERP成分反映出来，为不同的皮层来源提供了证据。(C)1999爱思唯尔爱尔兰科学有限公司。保留所有权利。
Event-related potentials (ERPs) were recorded while subjects monitored a visually presented sequence of stimuli that provided information about both a temporal pattern (rhythm) and a spatial pattern, and responded to rhythmical or spatial deviants. A third task, which required the monitoring of the same sequence for screen flickers served as a perceptual baseline condition and controlled for response preparation effects. The monitoring of temporal and spatial sequential information elicited negative slow potentials (SPs) over distinct topographical areas. Thus, attention to the temporal and to the spatial domain of one and the same stimulus sequence are reflected by distinct ERP components, providing evidence for distinct cortical sources.
