Early Vision Is Early in Time

Research output: Contribution to journalShort surveypeer-review


Roelfsema, Tolboom, and Khayat have found that neurons in primary visual cortex, V1, increase their spike firing rates to signal image segmentation and attention. V1 responses were in a temporal sequence: first to image motion, next to segmentation, last to attentional signals. The involvement of V1 with segmentation and attention suggests modifying the hierarchical view of visual perception.
