I need help answring:


  1. A. Why is it that some areas of the skin do not distinguish between stimuli very well, as evidenced in the two-point discrimination and temperature sensitivity experiments?

B. What does this indicate about the relationship between the density of receptors and the size of the receptive fiels?


2. Phantom limb syndrome is a phenomenon that often occurs after amputations, in which patients feel extreme pain sensations coming from the limb that has been removed. It is believed that phantom limb syndrome is related to the organization of the primary somatosensory cortex.

A. Hypothesize how this cortical representation might explain how one could lose a limb but continue to feel pain.

B. What does phantom limb syndrome tell you about the reality of our somatic sensation?
