This is a diagram showing two human brains within outline heads. Regions of recorded brain activity are coloured. The left is labelled ‘Visible word’, and there are seven patches of green seen across the brain where there is brain activity. The right is labelled ‘Invisible word’, and there are two small patches of red where there is brain activity. The larger of these is located near the base of the brain at the back and the second particularly small patch is near the centre of the brain. These both have a similar shape and location although smaller size to corresponding patches in the left brain.
