Another area of the brain, called the frontal eye fields, is important in helping you move your eyes toward an area that you deliberately choose to look at. This part of the brain makes a plan for the eyes so that they know how and where to move, based on your goals and the visual features of objects in your environment. A visual feature is something that describes an object, such as shape, size, or color. You can think of the frontal eye fields as a mapmaker. This area of the brain maps out the visual features of your environment and how important or noticeable they are. If you are looking for a round clock, the frontal eye fields mark round shapes as important. It might also mark an area as important if it is very attention grabbing, such as a hot pink coffee mug on a bland, brown table. The area of the map that is deemed most important overall is where your eyes will move next. Now that you know a little bit about how eye movements work, let us take a look at how and why scientists study eye movements.
