1. What is the 2-point threshold and what does it measure?
2. How does the 2-point discrimination relate to the magnification factor in the CNS representation of the body surface?
3. How does the 2-point discrimination relate to the size of the receptive field for various parts of the body?
4. Why do you think your entire body doesn't need to be as sensitive as your fingertips?
5. Make a bar/line graph showing the smallest discriminable distance (include the actual distance in inches) between 2 points at each tested spot on the body surface for each subject. (attach a picture of your graph) ( 10 parts + X/Y axes)
