Explain why individuals are often so insensitive to their own body and breath odor. How does sensory adaptation contribute to this insensitivity? How have advertisers tried to capitalize on this situation?
Imagine you wake up to the smell of smoke, The sound of the fire alarm, the flashing lights of sirens, the acreage taste of smoke in the air. In other words, all your senses are reacting to this emergency. Your body goes into "flight or fight mode".
Question: in about two paragraphs, can you describe the sensory pathway that the sensory information from just one of these special senses takes to the brain to be integrated.
for example, if you were describing the smell of the smoke, how was odor detected? Which cranial nerves are involved? Where are those located? Where do they connect to the rest of the brain?
Outline the place theory of pitch discrimination as an explanation of the human ear’s ability to distinguish sounds of different frequencies

- Compare and contrast general and special senses. Give two examples of each and describe the locations of the receptors that mediate these senses.arrow_forwardSensory adaptation occurs when the brain filters out repetitious and/or insignificant information. Indicate the correct example of sensory adaptation. a. hog farmer does not notice the barn smell from his working boots when he wears them on the porch of the house. b. A chef discriminates the aromas from prepared dishes as he uses exotic spices. c. A sommelier can differentiate the unique tastes among various blended wines given to him to evaluate. d. A person who inadvertently burns the tip of his or her tongue with a hot drink can still consume cold beverages.arrow_forwardCompare and contrast the senses of taste and smell by dragging the choices below into one or both of the categories. Labels Involves modified neurons Molecules bind to receptor proteins of microvilli and generate nerve signals in sensory nerve fibers Accounts for most of what we perceive as taste Reset All Sense of taste (1/2) Sense of smell (2/2)arrow_forward
- 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?arrow_forwardMany people believe that blind people have supernatural hearing. How would brain plasticity explain how enhanced hearing might result from greater reliance on hearing or from just using auditory information more effectively?arrow_forwardWhich method of sound localization is more effective for an animal with a small head? Which is more effective for an animal with a large head? Why?arrow_forward
- 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)?arrow_forwardUsing the ideas of the place theory of pitch and the tonotopic organization of the auditory cortex, explain how we perceive different pitches of sounds.arrow_forwardWhat is meant by a “tonotopic map”? a. Each location in the auditory cortex responds to a preferred tone, and these areas are arranged in order from low pitches to high pitches. b. The auditory cortex has axons back and forth to every other part of the cortex and several nuclei of the thalamus. c. Each neuron in the auditory cortex has a distinctive pattern of responding depending on the location of the source of sound in space. d. Each cell in the auditory cortex has a “partner” cell in the visual cortex.arrow_forward
- Watch this video (http://openstaxcollege.org/l/DanielleReed) to learn about Dr. Danielle Reed of the Monell Chemical Senses Center in Philadelphia, PA, who became interested in science at an early age because of her sensory experiences. She recognized that her sense of taste was unique compared with other people she knew. Now, she studies the genetic differences between people and their sensitivities to taste stimuli. In the video, there is a brief image of a person sticking out their tongue, which has been covered with a colored dye. This is how Dr. Reed is able to visualize and count papillae on the surface of the tongue. People fall into two large groups known as tasters and non-tasters on the basis of the density of papillae on their tongue, which also indicates the number of taste buds. Non-tasters can taste food, but they are not as sensitive to certain tastes, such as bitterness. Dr. Reed discovered that she is a non-taster, which explains why she perceived bitterness differently than other people she knew. Are you very sensitive to tastes? Can you see any similarities among the members of your family?arrow_forwardWhat is the "coincidence" in the Jeffress neural coincidence model? Two sound sources have the same frequency and amplitude at the same time. Signals arrive at two different neurons at the same time. Signals arrive from the two ears at the same time. Two sound sources are in the same location in the sound environarrow_forwardEnvironmental input to different sensory systems affects different neuroanatomical pathways. However, there is a basic, common pathway plan that most sensory systems share. Choose the response option that best describes that plan. receptors --> hindbrain --> midbrain --> cortical association area receptors --> medulla --> hypothalamus --> frontal cortex receptors -> spinal nerves --> midbrain --> temporal cortex receptors >brainstem --> thalamus --> primary cortical areaarrow_forward
