Visual fields have been found to have selective central sensitivity, which can make the field either excited or inhibited, depending on the stimuli on the field as well as on the surrounding receptors. So, if the central receptor is excited, the surrounding receptors are inhibited, and vice versa. This signal-processing system is quick and sensitive because it is either on or off, depending on the field’s neighbors’ state. This system helps you determine the edge boundary of an object, for example.

Notice that you detect the finger to be moving but not in motion. Now, still looking at your index finger, move it around as though you are drawing in three dimensions and the finger is flying. Keep your eyes on the finger and follow it as it flies. Now the combination of eyehead and retinal image detection gives rise to the sense of movement. You can achieve this same effect by asking another person to hold a pencil and move it around so that your hand movement does not influence you in your perception of the visual stimuli.
