Pain has been a topic of discussion in lecture on many occasions, perhaps because pain is something that most experience, but want to avoid. Though most experience some form of pain, incidents vary in intensity and people’s reactions are of different extremes, as well. Why? What causes these differences in pain tolerance? It was determined in class that pain is the result of certain pattern generators in the nervous system, so it is only natural that one looks to the brain to get to the root of pain tolerance. Research has been done that claims the source is genetic, psychological, or even gender-based. But in fact, this student believes that pain tolerance is the result of a combination of at least these three conditions.
