Answer to Question 1

Answer: A
Rationale: The case of Melissa in the chapter prologue makes the point that mind and body interact to determine pain reactivity.

Answer to Question 2

Answer: The lateral geniculate nucleus of the thalamus (LGN) is organized into six layers. The inner two layers contain large cells (magnocellular), while the outer four layers are comprised of small cells. The magnocellular layers project to portions of the striate cortex that mediate visual processes other than color (e.g., form, movement, and depth). The parvocellular layers are involved in the perception of color and fine detail.
