Neural substrates of visual spatial attention

Abstract: I will present examples of the effects of attention on visual perception and summarize our current understanding of the underlying neural mechanisms. Allocation of attention to a peripheral visual field location, without moving our eyes, enhances our perception of visual objects at the attended location, while our perception of visual objects at unattended locations is impaired. What are the neural correlates of this “spotlight” of attention? How does the brain select certain aspects of the environment for preferential processing? How are attended and unattended inputs processed differently in the brain’s visual system? I will describe a series of studies that employ human brain imaging methods to address these questions.
