In the chapter, The Pain Perplex, Gawande mentions three models or explanations for the pain puzzle in the human body: Cartesian model, Gate-Control Theory, and Lenzs explanation. Compare and contrast any two of these models or theories. For your research, you should consult at least three scholarly articles in addition to Gawandes book. You can consult some of the sources that Gawande refers to (257-58). In your discussion, consider the relationship between the mind and the body implied by these models. Which model is plausible or more correct in explaining the pain phenomenon in your judgment and why?
