A person with epilepsy had a successful surgery to prevent the spread of epileptic activity between the two hemispheres of the brain.
When an object is presented to the left visual fields of both eyes, this person can see the object but cannot verbally describe the object.
When the object is presented to the right visual fields of both eyes, this person can see the object and is able to verbally describe the object.
a. Describe the visual pathway from left visual fields to perception in the brain.b. Identify the area of the brain responsible for speech production. Include the name of the area, the lobe(s) and the hemisphere of the brain it is located in. c. Explain why there is a disconnect between vision and speech in the person described at the beginning of this question.
Explain the normal functioning of the eye to allow us to have visual acuity.
What is meant by visual acuity? How does the eye adjust to facilitate this?
Specifically, how do changes in near-point accommodation and astigmatism affect acuity?
What is the problem with changes in near-point accommodation and astigmatism and why are they problematic? How can each of these be measured? Can these conditions be corrected? If so, how? Do these conditions change as we age?
Mr. Ally went to the eye doctor and complained about dark areas in his vision. He had never noticed it before. There is no pain.
What is the diagnosis?
Explain the reason behind floaters and dark areas in the visual field.
How should the doctor treat Mr. Ally?

- How do we perceive stimuli in everyday life. Describe this pathway (do not list) for vision OR olfaction using the key words listed below. (Note: Be sure you can do this for sound and balance too) Start with the stimulus and end with its perception in the cortex. (Note: words are in no particular order). Key words for vision: photoreceptor, retina, light, visual cortex, optic nerve (CN II), action potentials, optic chiasm, optic tract, LGN of thalamus, “I see light!” Key words for olfaction: odorant, olfactory receptor cell, olfactory nerve (CN I), g-proteins, olfactory bulb, olfactory tract, olfactory cortex, action potentials, odor molecules. “I smell coffee!”arrow_forwardBryan has normal vision and is wearing a special headset that shows a picture of a sailboat to his left eye and a picture of a dog to his right eye. What is Bryan's perception of these images most likely to be? He will only perceive whichever image is presented to his dominant eye. He will alternate between perceiving the sailboat and perceiving the dog. He will perceive the dog and the sailboat overlaid on top of each other. He will perceive parts of the dog and parts of the sailboat combined together in a fashion similar to a puzzle.arrow_forwardUnilateral Cerebral strokes can cause deficits in motor control, somatic sensation and vision. However, they do not cause deficits in hearing. The explanation for this is: Auditory information does not reach the cortex Auditory information only goes to one hemisphere. Auditory information goes to both hemispheres How are the outer segments of photoreceptors positioned? between bipolar cells and horizontal cells in the outermost layer of the retina in the ganglion cell layer farthest from the pigment epitheliumarrow_forward
- Provide a step by step list of visual sensation through visual processing. Begin at light entering the eye through signal transduction, to the circuitry involved in the brain in understanding the "what" and "where" of the object. Be sure to review the specific criteria outlined in the rubric.arrow_forwardMany people think that vision is processed solely in the occipital lobe, and language in the temporal. Discuss why this is a poor heuristic and name at least three areas of major processing overlap in the frontal and/or parietal lobes.arrow_forwardCortical impairment of specific areas of visual integration can lead to deficient object recognition. Which part of the cortex if damage lead to this agnosias? superior temporal posterior area inferior temporal cortex occipital visual cortex parahippocampal cortexarrow_forward
- The lateral geniculate nuclei (LGN)are 6-layer structures in each hemisphere, which receive input from the retina from the ipsilateral and contralateral eyes. What is true of the layer distribution of the LGN regarding how they receive inputs from the eyes? layers 1, 4 and 6 from contralateral eye layers 4,5 and 6 from ipsilateral eye layers 2,3 and 5 from ipsilateral eye a) and c)arrow_forwardBlindsight is the condition in which someone with damage in the primary visual cortex reports that they cannot see an object, but can usually guess what that object is. This means that some visual representation must reach the frontal speech area. What non-thalamic pathway might do that? Question 8 options: A) The pathway through the suprachiasmatic nucleus B) The dorsal visual pathway C) The pathway through the superior colliculus D) The magnocelluar or M pathwayarrow_forwardYou are driving at night on a two lane road, and you see a bright light. The light pass through your pupil, and your lens concentrates the light at retina. This stimulates the visual pathway. Your visual association center processes the signal from your eye and determines the lights is from a flashlight that an old lady is holding while crossing the street. Your visual association center sends a signal to your primary motor cortex, which sends a signal down the lateral corticospinal tract. This signal then proceeds down the spinal cord, out the posterior gray horn of the spinal cord, and out the ventral roots of efferent motor neurons. The motor signal travels from the sacral plexus and out towards the sciatic nerve. To answer this question, number the following steps in the correct order starting with the signal exiting the sciatic nerve. Number in order from 1-15 ______The cycle repeats and now many muscle fibers in the gastrocnemius begin to contracts in unison. _____Calcium ions…arrow_forward
