The objectives of this course are to create a comprehensive understanding of the clinical phenomenology of higher functions of sensation including vision, hearing and balance. The visual system can be considered a window to the brain for clinicians. It is easier to examine than other sensory systems but necessitates a thorough and exacting knowledge of its function. Localization of brain function by pathology in the visual system is a well-recognized component in clinical neuroscience. The understanding of the formation of an optical image of the environment promotes and understanding of human function that exceeds the visual system. The auditory system promotes the ability of humans to hear and is an important component that contributes to global human function. The auditory system is well studied and recognized specific to its pathways of integration and pathological presentation that affects a large percentage of people in our society. Not only is the auditory system associated with hearing, but it’s functional consequences and pathology exceed the perception of sound. Closely link to the visual, auditory and somatosensory systems, is the system of balance that promotes stance and gait. This vestibular system integrates the sensory contributions from a multimodal system that measures our environment and allows us to coordinate ourselves in the environment of our world.
