Learning physical skills, such as to how to play the piano, is known as ‘procedural’ learning. Neuroscientists investigating the neural changes associated with procedural learning have generally found that the changes occur within the neural pathways responsible for performing the behavior and not in a separate area. Scientists often try to study general principles such as this by picking simple system that can be extensively investigated in the laboratory setting. A popular model system for this kind of skill learning is the ‘vestibulo-ocular reflex.’

The vestibulo-ocular reflex is a fancy name for our ability to keep our eyes steadily looking at some particular point despite movements of our head. Your eyes muscles compensate for head motion, shifting your eyes an equal and opposite amount. This keeps the image of the visual scene quite stable on the retina as we bounce about. The ‘vestibulo’ part of the name reflects the role of your sense of balance, or more precisely, the sense of head orientation and movement provided by the vestibular organs in your inner ear. The ‘ocular’ part indicates that the eyes are involved. And the ‘reflex’ part reflects that moving the eyes in this way is fast and automatic. You can’t not do this. (Have someone watch or film your eyes while you turn your head. No matter how hard you try not to, your eyes will counteract the motion of your head.)

The brain has to learn how far you should move your eyes in the opposite direction to the head movement. It must also dynamically adjust this reflex to take into account viewing distance between the eyes and head rotate about different axes . . . . Page 191/192
