Topic: initial afferent activity

Spatial attention is the process through which we prioritize processing at specific locations in space, occurring through both the enhancement of behaviorally important locations and the suppression of potentially distracting locations. Despite extensive research demonstrating that goal-directed spatial attention can influence processing in various visual regions, debate persists regarding its timing, particularly its influence on initial afferent activity in early visual cortices. In this study, we aimed to address this question using human electroencephalography. We used the C1 component, wh
