To accurately perceive the direction of moving objects, rats may exploit a small but very useful cluster of visual neurons, which seem to work in the same way as the "pattern cells" found in the cerebral cortex of primates. ...

The visual cortex makes up one of the largest regions of the brain, which is a testament to how much information we receive from our eyes. The primary visual cortex, or V1, is the first stage of processing visual input in ...
