1999: "Scientists at the University of California, Berkeley, have recorded signals from deep in the brain of a cat to capture movies of how it views the world around it. The images they reconstructed from the recordings were fuzzy but recognizable versions of the scenes that played out before the cat's eyes. The team recorded signals from a total of 177 cells in the lateral geniculate nucleus - a part of the brain's thalamus that processes visual signals from the eye - as they played a digitized movie of indoor and outdoor scenes for the cat. Using simple mathematical filters, the researchers decoded the signals to generate a movie of what the cat actually saw." Image Source:and Dream Views
