In this study, a variant of the n-back task was used to investigate electrophysiological correlates of top-down processes in visual-object working memory. Event-related potentials were used to replicate results concerning an attention related modulation of neural processes and to investigate the involvement of prefrontal cortex in this modulation. 16 healthy subjects executed an n-back task with sequentially presented faces and scenes. Attention was selectively directed to only one stimulus… CONTINUE READING
