Project Summary: Current computational models of visual processing focus on the bottom-up cascade of sequential operations from the retina onto primary visual cortex and higher level processing. Here we seek to understand how task goals modulate the responses along ventral visual cortex. The project will involve the quantitative analyses of neurophysiological recordings from human ventral visual cortex and the development of computational models that incorporate top-down feedback signaling carrying task information. We expect that this work will shed light on the mechanisms by which bottom-up sensory signals are integrated with top-down inputs carrying current goals.
