Results from psychophysics, neuroscience and computational modelling show that the rapid recognition of everyday objects can be explained by viewing the brain’s visual cortex as a multi-layer, feed-forward system in which the neural activity propagates from the eye to the higher brain areas, with little feedback from the higher layers to the lower layers.
Yet, there are as many feedback connections as feed-forward connections in the visual cortex, and the researchers will seek to understand their role.
