Looking through cats' eyes

On October 11, 1999 Professor Yang Dan at UC Berkeley demonstrated the technology that captures images of what a cat sees. This is one approach to the technical challenge to remotely acquire the vision of an animal. By recording the electrical activity of nerve cells in the thalamus, a region of the brain that receives signals from the eyes, Dr Yang and researchers from the university were able to view these shapes. They recorded the output from 177 brain cells that responded to light and dark in the cat's field of view. link
