Chapter 45.1, Problem 4R
Summary Introduction
To review:
The importance of adaptation in different sensory modalities.
Introduction:
The sensory receptors of the individual activate when they come in contact with any stimulus. Their stimulation causes the body to respond to the stimulus by various mechanisms. However, when the body is stimulated repeatedly by the same stimulus, sensory receptors start producing a weak or diminished response. Due to a weaker response, the individual is capable of only detecting the new changes or information and is able to ignore the conditions that have remained constant. This process of minimizing its response to repeated stimulation is called adaptation.

Why is pain considered an subjective sensory experience and not an objective sensory experience?
The sensory systems are complex and have the amazing ability to respond to different types of environmental stimuli. What is one aspect of the sensory systems we have looked at (gustatory, olfactory, or visual) that you found particularly interesting and would like to know more about?
M
Which of the following presents the elements of a sensory system in the correct order?
Select one:
Accessory structure modifies energy and sensory nerves transfer activity to central nervous system, thalamus processes
and relays activity to cerebral cortex, cerebral cortex transfers input to accessory structures and sensation or perception is
produced.
Accessory structure modifies energy, receptor transduces energy into neural activity, sensory nerves transfer activity to
central nervous system, thalamus processes and relays activity to cerebral cortex, cerebral cortex receives input and

- In the process of sensory coding Recruitment of additional neurons occurs with a weak stimulus in order to make the stimulus stronger. The larger the receptive field of a sensory receptor, the greater the expected acuity and the more accurate the two-point discrimination. Lateral inhibition of neighboring receptors resulting in a relative reduction of action potentials in the neighboring second order neurons would be expected to increase acuity. A receptor potential that remains suprathreshold into the absolute refractory period will result in additional action potentials.arrow_forwardA 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?

However, there is a basic, common pathway plan that most sensory systems share.
