Include a 5-10 sentence explanation of how the sheep’s eye senses light and relays that data to the brain to interpret visual information. Some pieces to consider: What path does the light travel? What structures and pigments does it interact with? How does the signal travel to the brain? Where in the brain is the data processed? How is this different in the high light vs low light? How might the sheep’s vision differ from our own?

Include a 5-10 sentence explanation of how the ear senses sound and relays that data to the brain to interpret auditory information. Some pieces to consider: What path does the sound travel through the ear? What structures do the waves interact with? How does the signal travel to the brain? Where in the brain is the data processed? How does this sense change with age? What could cause deafness in humans (there are at least two major ways this can happen)?
Review how photoreceptors within the eye detect light and transmit that information to the brain, by identifying each lettered structure in the figure below and answering the questions that follow: A: B: C: D: E: F: G: Which structure responds to color?: Which structure responds to dim light and movement?: Which two structures release neurotransmitters in response to light?: Which structure binds to those neurotransmitters, relays an action potential, and releases a second set of neurotransmitters?: Which structure binds to this second set of neurotransmitters and relays an action potential through the optic nerve to the brain?: Which direction does light travel through the retina? Toward the choroid or away?: Which direction do neural signals travel through the retina? Toward the choroid or away?:
You discover that the convergence ratio for the photoreceptors in the Zerons is opposite to that of humans, i.e the convergence ratio for rods is lower and the convergence ratio of cones is higher. The site and distribution of the photoreceptors is the same as in humans. Question: What might be true for Zerons vision? The images formed in the dark are sharper than those formed in light The central parts of their visual field aren't as sharp as the peripheral parts of their visual fields. They are better at forming color contrasts in images They have poor differentiation between black and white
How does the eye transduce light energy into a neural message? What is the blind spot in the eye and how does it impact the transduction of light energy? Please include references.
Watch this video (Links to an external site.) to learn more about how the brain perceives 3-D motion. Similar to how retinal disparity offers 3-D moviegoers a way to extract 3-D information from the two-dimensional visual field projected onto the retina, the brain can extract information about movement in space by comparing what the two eyes see. If movement of a visual stimulus is leftward in one eye and rightward in the opposite eye, the brain interprets this as movement toward (or away) from the face along the midline. Which eye is visualizing leftward stimulus?
Select the options that properly describe the function and features of rods. The absorbance of rhodopsin in the rods is much more sensitive than in the cone opsins. O The absorbance of rhodopsin in the cones is much more sensitive than in the rods opsins. sensitive to bright light conditions. O Rods are sensitive to vision in bright light conditions. O In low light conditions rods perceive color as blue scale. O In low light conditions rods perceive color as gray cale. O sensitive to low light conditions. Rods are sensitive to low light conditions. OA bright blue light would stimulate rods more than cones. O Rods are sensitive to vision in low light conditions. OLow light conditions are viewed in blue scale. Rods are sensitive to bright light conditions.
Which of the following is the best explanation of why it is difficult to discriminate the color of an object at night? Rods contain a single visual pigment. As many as 100 cones may converge on one ganglion cell. Cones come in three types, each sensitive to different wavelengths of light. The fovea are densely packed with cones.
Here you see an astigmatism illustration. Please explain why astigmatisms cause blurred vision in the context of our sense of sight. Please do not merely say “The light rays do not hit the focal point”. Please explain why that matters for the sense of sight.
Put the following steps in order for transduction for vision. Question options: PDE breaks down cyclic GMP Photon is absorbed by discs the photoreceptor hyperpolarizes Sodium channels are inactivated and the dark current stops Opsin is activated Phosphodiesterase (PDE) is activated Transducin is activated
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?
Human color vision is "produced" by the nervous system based on how three different cone receptors interact with photons oflight in the eye. These three different types of cones interact with photons of different frequency light, as indicated in the following chart:
Select the options that properly describe the function and features of cone cones can see red, glue and green. A A bright blue light would stimulate rods more than cones. O In low light conditions cones perceive color as gray cale. O In low light conditions cones perceive color as blue scale. O cones view low light conditions in grayscale. O cones are sensitive to bright light conditions.
