The analytical or intellectual portion of the brain processes the spatial infor- mation not as visual images, but as data. When you identify the shapes you are seeing as trees, cars, people and so on, you are using the intellectual brain. This is the right tool for just about every other conscious activity of your life. But when you use this part of your brain to draw, the results are disastrous. It first trans- lates the visual information it has re- ceived from the spatial brain into data, then creates a simplified visual symbol to stand for the information.
