TY - JOUR ID - citeulike:1352976 L3 - citeulike-article-id:1352976 N2 - Human observers continue to experience a visual stimulus for some time after the offset that stimulus. The neural activity evoked by a visual stimulus continues for some time after its offset. The information extracted from a visual stimulus continues to be registered in a visual form of memory ('iconic memory') for some time after its offset.
