Question 18 options: a metamer a subtractive colour match an additive colour match a photon equivalence Which of the following accurately describes the ascending pathway for auditory information? Question 33options: Medial geniculate nucleus to inferior colliculus to auditory cortex. Auditory cortex to inferior colliculus to medial geniculate nucleus. Auditory cortex to medial geniculate nucleus to inferior colliculus. Inferior colliculus to medial geniculate nucleus to auditory cortex.Given what you already know about the sensation of pain, what is the expected change in membrane potential when pain is felt by sensory receptors? Select one: a. The nerve impulses increase in strength and lower the threshold potential. b. The nerve impulses occur more frequently, thereby transmitting more action potentials according to the intensity of pain. c. The nerve impulses occur more frequently and prevent neurons from entering the refractory period. d. The nerve impulses increase in strength, thereby making the maximum membrane potential higher than normal.What are some general similarities in how receptive fields are represented by the nervous system? What advantage does this give us with respect to those senses?
- In general, could we name the sensory receptors “middle men” between the stimulus and the peripheral nervous system? Please shortly explain your answer.If a monkey is trained to grab and squeeze a squeaky ball, when would mirror neurons fire? (Select all that apply) Select all that apply: a.

- Which senses correspond to which lobes of the brain? I know sound is located in the temporal lobe, taste is located in the parietal lobe, but I am not sure of the rest.What are the similarities in how receptive fields are represented by the nervous system? What advantage does this give us with respect to senses?Which of these is the BEST example of top-down processing? When Sarah listens to someone speaking Spanish, she can easily hear where one words ends and another begins because she is fluent in Spanish. Shane's sense of taste is based primarily on the chemicals that activate receptors on his tongue. John is able to see blue objects because he has cones that respond to short-wavelength light. Tamara's perception of line length is driven primarily by the true length of the line in space.
