Representation of Objects and Scenes in Visual Working Memory in Human Brain

  • Jun Saiki

Abstract

To interact efficiently with our world, not only perception of objects and scenes, but also maintenance of visual representations for a brief period is indispensable. In scene and object perception and recognition, this chapter focuses on explicit scene understanding composed of maintenance of object representations, dynamic updating of object representations, and formation of object representations by feature binding. Research on these component processes is first reviewed, and then their coordination, particularly the maintenance and updating of feature-bound representations, is discussed. Multiple feature-bound representations may be maintained and updated in parietal area, or alternatively, a limited number of feature-bound representations may be formed in anterior prefrontal area only when necessary. Recent studies using multiple object permanence tracking (MOPT) paradigm showed that both anterior prefrontal and frontoparietal network are necessary to maintain feature-bound representations, suggesting that the latter view may be more plausible.
