Select the statement that best describes the organization of the somatosensory cortex.
a. A distorted neural representation of the body space is due to differences in the number of neurons that code high- and low-resolution areas.
b. None of the answers.
c. The body area is represented by a single map in the primary somatosensory cortex (S1).
d. A secondary somatosensory cortex is unnecessary since all somatosensory information is processed in the primary somatosensory cortex (S1).
e. A proportional neural representation for each region of the body yields a realistic map of body space.
