8. Which of these is NOT a feature of taste?

a) Taste
b) Smell
c) Touch
d) Sight

10. One of statements given below about transduction is INCORRECT. But which one?

a) Action potentials represent electrical energy derived from the exchange of electrically charged ions across the neuronal membrane.
b) Our eyes transduce electromagnetic radiation (light) into action potentials.
c) Our ears transduce the mechanical energy of sound.
d) Transduction is a term which only applies to sense organs.

11. Which is an actual feature of the retina?

a) It signals the points of change in the visual image.
b) It ignores regions where no changes occur.
c) Both (a) and (b).
d) Neither (a) nor (b).

12. What are the two streams of visual information in the cortex and how do they differ?

a) The ventral stream processes information about the nature of objects and the dorsal stream allows us to interact with objects
b) The ventral stream allows us to interact with objects and the dorsal stream processes information about the nature of objects
c) The excitatory stream produces more neuronal firing in response to light stimuli and the inhibitory stream produces less neuronal firing in response to light stimuli
d) The excitatory stream produces less neuronal firing in response to light stimuli and the inhibitory stream produces more neuronal firing in response to light stimuli
e) None of the above

13.Which of the following is true in relation to moving the eye to many locations?

a) The eye may need to be moved to so many locations in order to resolve fine detail.
b) Selective attention involves moving our eye to a given location, but processing the information from that location in less detail than information from elsewhere.
c) There appear to be three streams of visual information in the cortex.
d) Ventral streams allow us to plan actions without a detailed representation of objects.
