The Role of the Pulvinar in Spatial Visual Attention.
This chapter deals with the role of the pulvinar in spatial visual attention. There are at least two aspects in which the pulvinar seems to be instrumental for selective visual processes. The first aspect concerns pulvinar connectivity pattern. The pulvinar is connected with brain regions known to be playing a role in attentional mechanisms, such as area V4, the superior colliculus (SC), and the inferior parietal cortex (IP). Additionally, the pulvinar is richly interconnected with multiple cortical areas. This enables the pulvinar to serve as a hub for brain communication, potentially gating the flow of information across different regions. The second aspect concerns neuronal circuits intrinsic to the pulvinar. We claim these circuits are subserving three basic steps regarding the allocation of spatial attention: disengaging from the current focus of attention, moving it to a new target, and engaging it at a new position.
期刊介绍:
"Advances in Anatomy, Embryology and Cell Biology" presents critical reviews on all topical fields of normal and experimental anatomy including cell biology. The multi-perspective presentation of morphological aspects of basic biological phenomen in the human constitutes the main focus of the series. The contributions re-evaluate the latest findings and show ways for further research.
