a. Explain the difference between labeled line and population coding in sensory systems, including characteristics of constituent neurons.

b. Compare the suitability of labeled line and population codes for discriminating odorants (olfactory stimuli) or colors.

c. You could argue that the visual system and the optic nerve illustrate attributes of both population and labeled-line codes. Do you think this is true? Justify your answer.
