We are interested in on how our brain copes with the myriad of information that hits our senses every second and how the brain creates an image of our environment that we can effectively deal with. The one important cognitive function that controls the way we perceive our world is attention. Kanwisher & Wojciulik (Nature Rev Neurosci, 2000) put it this way: “We are not passive recipients of the information that impinges on our retinae, but active participants in our own perceptual processes. Visual experience depends critically on attention. We select particular aspects of a visual scene for detailed analysis and control of subsequent behavior, but ignore other aspects so completely that moments after they disappear from view we cannot report anything about them. …Functional neuroimaging is revealing much more than where attention happens in the brain; it is beginning to answer some of the oldest and deepest questions about what visual attention is and how it works.” Our research focuses on how attention modulates neural activity in sensory systems. We have assessed this in situations in which subjects have to adjust the size of the visual field region they are attending, or have to split attention between non-contiguous locations of the visual field or have to deal with distracting information or simultaneous auditory and visual stimulation. |
