报告题目：New perspective on visual attention
报告摘要：Attention is commonly believed to be controlled by a network of areas in the cerebral cortex, with frontal and parietal cortex regulating limited resources available in the sensory areas of cortex. However, subcortical structures like the superior colliculus also play a role in attention, and in this talk I will explain how our investigation of the superior colliculus has led us to a very different view of how attention is controlled. I will present evidence that the superior colliculus plays a crucial role in the control of spatial attention, but surprisingly, the mechanisms used by the superior colliculus appear to be independent of the well-known signatures of spatial attention in visual cortex. These recent results demonstrate that processes beyond the well-known correlates in extrastriate cortex play a major role in visual spatial attention. Furthermore, based on recent results from fMRI and physiology experiments in my lab, as well as clues from neuroanatomy and disorders of attention, I speculate that the brain mechanisms for attention are based on an evolutionarily conserved ciruit motif that predates the emergence of the neocortex.
