Textbook Question
Chapter 41, Problem 11TYK
Discuss Concepts In owls and many other birds of prey, the fovea is located toward the top of the retina rather than at the center as in humans. This arrangement correlates with the birds’ hunting behavior, in which they look down when they fly, scanning the ground for a meal. With this arrangement in mind, why do you think a standing owl would turn its head upside down?

The function of the vertebrate eye is unusual compared with other processes found within the body. For example, the direction in which sensory information flows is actually opposite to the path that light takes through the retina. Explain the sequence of events involved in the movement of light and information through the structures of the eye and explain why they move in opposite directions. Compare this sequence to the functioning of the Mollusk eye.
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?
PET (positron emission tomography) scans of the brains of people who have been blind since birth reveal high neural activity in the visual centers of the cerebral cortex when these people read Braille. However, when sighted individuals run their fingers over the raised letters of Braille, the visual centers do not show increased activity. Explain these experimental results.

- Why would it be an advantage for a deer to have a wide visual field, as compared to overlapping, stereoscopic vision?arrow_forwardTure or False:(T/F) A bee would detect the odor of the flowers using trichoid sensilla located on the antennae and the olfactory information would be processed in the glomeruli of the deuterocerbrum and incorporated into olfactory learning in the corpora pedunculata of the protocerebrum.(T/F) A bee would monitor and control flight speed using interommatidial hairs and the optomotor response.(T/F) Stresses and strains on the exoskeleton during flight would be monitored by basiconic and coeloconic sensilla located in the wing hinge.arrow_forwardWhen you exit a dark room into a brightly lit environment, within seconds, you to see a crisp view of your surroundings. However, when you enter a dark room from a brightly lit environment, your eyes might take more than 10 minutes to become used to the new surroundings. Your eyes are waiting for: a. the rods to begin to function b. the cones to begin to function c. the pupils to get smallerarrow_forward
- The vertebrate eye is often called a camera eye for its many resemblances to the mechanisms of a film camera. List as many comparisons as you canarrow_forwardDistinguish between static and dynamic equilibrium. The sense of equilibrium (balance) is really two senses— static equilibrium and dynamic equilibrium—that come from different sensory organs. The organs of static equilibrium (stat′ik e″kwı˘-lib′re-um) sense the position of the head, maintaining balance, stability and posture when the head and body are still. When the head and body suddenly move or rotate, the organs of dynamic equilibrium (di-nam′ik e″kwı˘- lib′re-um) detect such motion and aid in maintaining balance.arrow_forwardWhen a person blinks, the part of the brain that interprets visual stimulation is suppressed. The spontaneous act of blinking is controlled by the area of the brain that controls involuntary movements such as breathing and blood pressure. To determine whether the lack of light or the act of blinking causes the suppression, scientists had subjects close their eyes and then placed a bright flashing light in their mouth to stimulate the photoreceptors in the eyes through the palate. Visual stimulation was still suppressed. So the photoreceptors in the retina were not stimulated even though they were exposed to light. This study demonstrated that when a person blinks, it is the act of blinking and not the absence of light that causes the suppression of visual stimulation. In the diagram above, identify the part of the brain that is suppressed during blinking and the part of the brain that controls involuntary, spontaneous blinking.

- I need help finding a research paper and a news article that evaluates how brain and mind are presented outside the scientific literature. Specifically, you’ll choose an empirical study (2020 or earlier) that was featured in news reports and critically evaluate its presentation there in light of the original research paper. The topic is about visual perception in animals or humans . We already spoke about mantis shrimp so that example is not available however it can be any other animal.arrow_forwardHere 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.arrow_forwardWatch 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?arrow_forward
- Most animals lack cones in their retinas. How, then, do such animals view the visual world?arrow_forwardThe computational level of analysis in Marr's theory might be concerned with A the specific brain mechanisms that are responsible for edge detection. B the individual receptive fields that accomplish a 2.5 D sketch. C the problem of how the visual system extracts information about the three-dimensional structure of an object from a flat retinal image.arrow_forwardHuman 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:arrow_forward
