In this exercise, you will study the major structures of the visual sensory and visual motor systems. The visual sensory pathway from the eye to the occipital cortex is involved in the processing of complex visual imagery. Neurons within this system respond selectively to specific patterns of light, such as contours, and to light of different wavelengths, i.e., color. This pathway is organized in a topographic manner, a feature that contributes to our ability to recognize objects and accurately localize objects in visual space. Knowledge of this topographic organization is important clinically since visual field deficits serve as useful indicators of the site of damage. You will also examine the visual/ocular motor pathways involved with controlling the eye blink reflex, eye movements, pupil size, and near vision responses.


At the conclusion of today's laboratory you should be able to:

  1. Identify the principal structures of the eye.
  2. Identify the major components of the visual pathway.
  3. Identify the neural connections underlying visual motor responses.
