A:
- How do receptors encode modality? Stimulus intensity? What is adaptation in a receptor?
Step by step
Solved in 2 steps with 2 images
- How is a sensory system able to maintain sensitivity across a wide range of stimulus intensities? What is range fractionation? How do receptors encode modality? Stimulus intensity? What is adaptation in a receptor? How do hair cells encode sound and sound intensity?What is meant by the modality of a stimulus? Give someexamplesWhat is the difference between stimulus generalization and stimulus discrimination? Provide examples
- What is the mechanism used by the central nervous system to resolve the inconsistency inherent during the encoding stimulus location and intensity?Environmental 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 areaA light signal activates a photoreceptor, which, in turn, activates a bipolar cell. Horizontal cells in the retina inactivate the surrounding bipolar cells. Which of the following is the correct sensory system property that this example is describing? Frequency coding Population coding Stimulus type O Lateral inhibition Receptor adaptation
