What fMRI has taught us about human vision

Curr Opin Neurobiol. 1997 Aug;7(4):554-61. doi: 10.1016/s0959-4388(97)80036-0.


The recent application of functional magnetic resonance imaging (fMRI) to visual studies has begun to elucidate how the human visual system is anatomically and functionally organized. Bottom-up hierarchical processing among visual cortical areas has been revealed in experiments that have correlated brain activations with human perceptual experience. Top-down modulation of activity within visual cortical areas has been demonstrated through studies of higher cognitive processes such as attention and memory.
