在人类中研究了与选择性地关注刺激的位置和类型相关的负脑电位的半球差异。这种负性的早期部分（刺激后125-222 ms之间）与关注刺激的位置有关。它在中央头皮区域是对称的，但在后头皮区域的对侧视野的半球更大。这种负性的后期部分（刺激后222-272 ms）主要与关注给定位置处呈现的不同类型的刺激之一有关，并且在头皮的左后区域更大。这些结果被解释的关系，在不同类型的信息处理的时间过程中，在左，右半球。
Hemispheric differences in a negative brain potential associated with selectively attending the location and type of stimulation were investigated in humans. The earlier portion of this negativity (between 125-222 ms after stimulation) was associated with attending the location of the stimulus. It was symmetrical in the central scalp regions but was greater in the hemisphere contralateral to the attended visual field in the posterior scalp region. The later portion of this negativity (from 222-272 ms after stimulation) primarily was associated with attending one of the different types of stimuli presented at a given location and was greater over the left posterior regions of the scalp. These results were interpreted in relationship to the time-course of different types of information processing in the left and right hemispheres.
