Question
Chapter 49.3, Problem 3CC
Summary Introduction
To explain: The difficulty faced by a person with severed corpus callosum to put a name to the face after seeing a familiar picture in left and right field of vision.
Concept introduction:
The left hemisphere of the brain plays a greater role in the language, math and logical operations. The right hemisphere of the brain plays a major role in the recognition of faces, spatial relations and non-verbal thinking.

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_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
- Many 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_forwardThere are a number of commonalities between the sensory systems both in terms of how incoming sensory information is processed and in terms of how that incoming information is interpreted and understood by the brain. Describe 3 commonalities across systems on the “sensory side” of the process and 2 commonalities on the perceptual side. Use examples in your descriptions.arrow_forwardList the brain structures involved in conscious object recognition from the eye to its final cortical destination.arrow_forward
- Watch this video (http://openstaxcollege.org/l/occipital) to learn more about a transverse section through the brain that depicts the visual pathway from the eye to the occipital cortex. The first half of the pathway is the projection from the RGCs through the optic nerve to the lateral geniculate nucleus in the thalamus on either side. This first fiber in the pathway synapses on a thalamic cell that then projects to the visual cortex in the occipital lobe where seeing, or visual perception, takes place. This video gives an abbreviated overview of the visual system by concentrating on the pathway from the eyes to the occipital lobe. The video makes the statement (at 0:45) that specialized cells in the retina called ganglion cells convert the light rays into electrical signals. What aspect of retinal processing is simplified by that statement? Explain your answer.arrow_forwardWhy is it easier to see images at night using peripheral, rather than the central, vision? Cones are denser in the periphery of the retina Bipolar cells are denser in the periphery of the retina Rods are denser in the periphery of the retina The optic nerve exits at the periphery of the retina.arrow_forwardWatch this video (http://openstaxcollege.org/l/reflexarc) to learn more about the reflex arc of the corneal reflex.
