本研究的重点问题是，是否间和通道内形式的注意反映在激活相同或不同的大脑区域。当受试者被呈现一个随机的视觉和听觉刺激序列时，记录ERP。他们被指示关注听觉或视觉刺激的非空间属性，并检测所关注通道内偶尔出现的目标刺激。枕叶选择负性被发现的视觉刺激的内模注意。视觉通道间注意也表现为类似的消极性。枕下内侧区的对称偶极子对可以解释模态内效应。偶极对间的注意力效果有一个稍微更后的位置相比，偶极对内的影响。听觉通道间的注意表现在早期增强的负性重叠的N1和P2组件，这是本地化使用对称偶极子对在外侧听觉皮层。通道内注意力效应的发生时间稍晚（约200 ms），并反映在额叶处理负性上。目前的研究结果表明，内和通道间的形式的注意确实是相似的视觉刺激。听觉数据表明涉及多个大脑区域。
The present study focuses on the question of whether inter- and intramodal forms of attention are reflected in activation of the same or different brain areas. ERPs were recorded while subjects were presented a random sequence of visual and auditory stimuli. They were instructed to attend to nonspatial attributes of either auditory or visual stimuli and to detect occasional target stimuli within the attended channel. An occipital selection negativity was found for intramodal attention to visual stimuli. Visual intermodal attention was also manifested in a similar negativity. A symmetrical dipole pair in the medial inferior occipital areas could account for the intramodal effects. Dipole pairs for the intermodal attention effect had a slightly more posterior location compared to the dipole pair for the intramodal effect. Auditory intermodal attention was manifested in an early enhanced negativity overlapping with the N1 and P2 components, which was localized using a symmetrical dipole pair in the lateral auditory cortex. The onset of the intramodal attention effect was somewhat later (around 200 ms), and was reflected in a frontal processing negativity. The present results indicate that intra- and intermodal forms of attention were indeed similar for visual stimuli. Auditory data suggest the involvement of multiple brain areas.
