    Pain is a necessary aspect of life. It can be broken down into two parts: emotional pain and physical pain. The latter could be a burn or a broken bone and is felt by the nerves in the skin that send signals to the brain. Emotional suffering is a pain not felt by nerves, nor can it be seen like a broken bone on an X-ray. Both make life uncomfortable but unfortunately, both are necessary. Getting hurt could mean both in an emotional or physical way but, without pain, there would be no way to tell if anything was wrong. The protagonist, Amir, and his father, Baba, in Khaled Hosseini's The Kite Runner, struggle with emotional pain throughout their lives. This is not a good way to lead a life, but the two characters add to the major theme of Hosseini's novel: pain is what motivates people to redeem themselves after hurting someone they love. Firstly, Amir struggled not with what he did, but rather what he did not do. After many years, he still struggled with what happened “the winter Hassan stopped smiling” (47). The rape of Hassan was a major factor in Amir’s guilt. Amir also felt bad for getting rid of Hassan and Ali. Even though Hassan and Ali are not physically there to remind Amir about his past, he still had troubles with his guilt because Hassan did not leave his thoughts. He had troubles with thinking of Hassan so much he started to feel physical episodes because of the guilt from Hassan’s rape as well as the guilt from getting rid of his family’s closest friends. Amir…

    The intricate reaction between the human’s physiological and psychological responses has been long disputed (Rowbotham, 2001) This ever changing discussion may be explained by the neuromatrix pain theory (Melzack, 1999). However, our understanding of the physiological response to a painful experience and its effects on the body has changed over the years. In the mid-17th century the pain theory was over simplified; nerve impulses travelled to the cerebral cortex in the brain, the more damage the…

    Population Coding There are a variety of neurons types needed to code for specific patterns of a stimulus. These neurons work together to encode information which cannot be done precisely by one neuron type alone. This principle is summarized by the theory of across-neuron response pattern (ANRP). Which states a stimulus will activate a uniquely different set of patterns to discriminate between another stimuli. This is depicted by the absolute difference of neural mass. Somatosensory system…
