Question
Chapter 41, Problem 13TYK
Summary Introduction
To review:
The reason due to which only 3% of the somatosensory cortex is responsible for hearing while 30% of the sensory cortex is responsible for vision, based on natural selection.
Introduction:
The sense organs are not just present in vertebrates but are also present in different forms in invertebrates and single-celled organisms as well. The single-celled organisms are able to detect a chemical change in water. Invertebrates have very simple types of receptors that help them detect any change in their environment so that they could move to a safe harbor. The visual receptors and auditory receptors have evolved over the course of time. It has been speculated that eyes were the first sense organ that developed in living organisms.

The following passage comes from an abstract in a study about analyzing hearing
loss in twins:
"A clinical and genetic study on 25 twin pairs with at least one deaf member was
performed. Concordance rate of hearing loss was 0.88 in MZ and 0.50 in DZ pairs"
(MZ =monozygotic or identical twins. DZ -Dizygotic or fraternal twins). From this
data alone, what can you conclude about the roles of environment and genetics in
hearing loss? Explain how you reached your conclusion.
Describe sensory adaptation and then give one example of a case in which one might interpret this to be an advantage and one that could be considered a disadvantaged.
Please consider explaining all the blanks in a step by step detailed manner.

- Which of the following is an illustration of experience-dependent plasticity? A) Rats raised in cages with toys have more dendritic spines and more synapses per neuron than rats raised in cages without this stimulation B) The brain expects experiences that all humans have (such as visual and auditory input) and uses them to shape the structure of the brain. C) Adults who became blind early in life were better able to discriminate musical pitch than were those who became blind later in life. D) All of the abovearrow_forwardI 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_forwardCan you help me determine which graph is best suited for each?arrow_forward
- Ture 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_forwardYou are tasked with devising an experimental approach for studying local spiking interneurones (LSINs) that respond to touch stimulation of the middle legs in locusts. Your experiments need to address three questions: i. Do some or all LSINs receive input from both middle legs? ii. Do some LSINs receive inhibitory tactile input? iii. Do the receptive fields of different LSINs overlap? The recording equipment available to you permits the use of only one recording electrode at a time. Specify and justify your choice of recording site and recording technique (intra- or extracellular), and briefly explain your strategy for addressing questions i–iii.arrow_forwardInclude 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_forward
- Which of the following statements about sensory systems is NOT true? a. Sensory transduction involves the conversion (by either a direct or indirect mechanism) of a physical or chemical stimulus into changes in membrane potential difference. b. Sensory adaptation plays a role in the ability of organisms to discriminate between important and unimportant information. c. The term "sensory adaptation" refers to the process by which a sensory cell becomes less sensitive, or less responsive, to a continuing source of stimulation. d. In general, a stimulus causes a change in the flow of charged ions across the plasma membrane of a sensory receptor cell. e. The more intense a stimulus is, the greater the peak depolarization of the action potentials fired by the sensory neuron.arrow_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_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
- Outline the place theory of pitch discrimination as an explanation of the human ear’s ability to distinguish sounds of different frequenciesarrow_forwardThe animal in the image below has 22 spikey appendages radiating from its nose that help it search through soil for small insects to eat. This star organ is highly sensitive to touch and is heavily innervated. Two-point discrimination experiments reveal that some of the appendages have a denser array of sensory receptors than any other appendages. If you were able to examine the somatosensory cortex of this animal, what organization might you expect to see? In your response, make comparisons to sensory systems in other animals.arrow_forwardReview 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?
