Even at the moment when we feel the light and heat of a fire, the inside of our brain is
                          pitch dark and its temperature never changes.




































                         Bundles of light coming from an object falls upside-down on the retina. Here, the image is
                         converted into electrical signals and transmitted to the centre of vision at the back of the
                         brain. Since the brain is insulated from light, it is impossible for light to reach the centre of
                         vision. This means that we view a vast world of light and depth in a tiny spot that is
                         insulated from light.
