Vision, Senses, and Motor Control Worksheet
Label the different sections by filling in the blanks on the visual cortex diagram, and answer the following questions in a minimum of 50 words each.
1. What are the functions in visual processing of each of the major structures identified on the diagram? Include a brief summary of each function in your response.
The functions of visual processing of the optic nerve is that it supply the sensory ability of the eyes to take into possession of light. Detect the presence of light. Optic chiasm allows the passage of information from the optic nerves. It is also where the information from both eyes crosses over in the brain. Which allows the information from both eyes to be processed together. Optic tract is in fact comprised of two tracts: the left optic tract and the right optic tract. The left optic tract convey information from temporal retinal fibers from the left eye and nasal retinal fiber from the right eye. The right optic tract convey information from the temporal retinal fibers from the right eye and nasal retinal fibers from the left eye. Lateral geniculate nucleus primary is the processing center for the visual information the is received from the retina of the eye. Superior colliculus is the rostral two bumps on each side on the dorsal aspect of the midbrain. the superior colliculus is convey an impression of the visual reflex center.
2. What is an example of a visual deficit associated with brain damage, disorder, or disease affecting the visual pathway? Provide a description of where the damage may occur and what functional visual deficits may arise.
The ambient process provides information about where one is in space and contributes to balance, movement, coordination and posture. Nerve fibers from the peripheral retina, part of the ambient visual system, are directed primarily to the midbrain where...
