Animal/Nonanimal Categories (IMAGE) McGovern Institute for Brain Research Caption Both humans and a computer model developed in Poggio's lab correctly categorize these images when they are presented for just 50 milliseconds followed by a mask that shuts down cognitive feedback in the human subjects. These results support the view that rapid or immediate object recognition occurs in one feed-forward sweep through the ventral stream of the visual cortex.
