Spatiotemporal characteristics of form analysis in the human visual cortex revealed by rapid event-related fMRI adaptation
Z Kourtzi, E Huberle - Neuroimage, 2005 - Elsevier
The integration of local elements to coherent forms is at the core of understanding visual
perception. Accumulating evidence suggests that both early retinotopic and higher …

The integration of higher order form and motion by the human brain
Our experience with a dynamic environment has tuned our visual system to use form and
motion as complementary sources of information for object recognition. To identify the neural …
