    1. Oculomotor System Systems Neuroscience 2012 Why study eye movements? Peripheral oculomotor apparatus Five types of eye movements Anatomy, physiology and function

    2. Why eye movements? Goal: How does the brain work? How do we combine current (sensory) input with past history of input (learning & memory) to select and control particular actions? (Behavior; perception?) Eye movements are the right level of complexity Continuum: stretch reflex to playing squash Complex, yet highly constrained (although that's not obvious) Other pluses: Output is easy to measure Input is easily specified and delivered Peripheral apparatus is straightforward Good animal models available: - Can record single neurons at a fast time scale - Can intervene in the system (lesion, stimulate, inject drugs, etc) to test specific hypotheses - Specialized animal models

    3. Musculature
