- An example of a sensory neuron is one that leads from a pain receptor in the finger to the spinal cord. A pin can be pressed against the skin without eliciting a response from the pain receptor. However, if the pin is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly be withdrawn through a reflex arc. How do we sense different types of pain (very painful vs. not painful at all)? Using your knowledge of threshold potential and the all-or-none principle, explain how it is possible to sense different levels of pain.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.There are a number of commonalities between the sensory systems both in terms of how incoming sensory information is processed and in terms of how that incoming information is interpreted and understood by the brain. Describe 3 commonalities across systems on the “sensory side” of the process and 2 commonalities on the perceptual side. Use examples in your descriptions.

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 produces sensation and perception. Ob. C. External receptors transduce energy into neural activity, sensory nerves transfer activity to central nervous system and relays activity to cerebral cortex, cerebral cortex receives input and produces sensation and perception. O d. Accessory structure modifies energy, receptor transduces energy and thalamus processes and relays activity to the reticular…The thalamus has been described as a “switchboard.” Explain why, by describing the pathway of somatic sensory information from the receptors to the cerebral cortex. Case Study: Princess Leia has asthma, and had to use her inhaler before taking her physiology exam. Later, in the physiology laboratory, she measured her pulse rate and blood pressure and found them to be higher than usual. The following week, after administering some drugs (epinephrine, atropine) she later developed a severe headache and dry mouth. When she looked in the mirror she noticed that her pupils were dilated.
- Define accommodation (aka adaptation) of receptors and give two examples of such.Which statement about color perception theory is true? The mechanisms involved in opponent-process theory take place earlier in the perceptual process than those involved in trichromatic theory. The processes proposed by both trichromatic theory and opponent-process theory take place in the primary visual cortex. Trichromatic theory and opponent-process theory are both strongly supported by behavioral and physiological evidence. Recently, trichromatic theory has overtaken opponent-process theory as the best explanation of color and hue perception.What is the best physiological explanation as to why a particular area has a low two-point threshold? A greater skin surface area always results in a lower two-point threshold because there is physically more room in which to house sensory receptors. With a low two-point threshold, there is a greater density of sensory receptors to allow for more precise location of the sensation by the somatosensory cortex. O A low threshold suggests a decreased sensation in that area, meaning a wide receptive field on that area of skin.
