Besides NPY, there are other neurobiological mechanisms that are believed to play a role in resilience. One factor, the brain-derived neurotrophic factor (BDNF), is important in studying stress responses. BDNF is a nerve growth factor that has been observed to be affected by stress. The BDNF expressed in the hippocampus decreases when exposed to stress, but in the nucleus accumbens, stress increases BDNF levels. (Feder, 2009) A study on BDNF levels in rats exposed to chronic stress established there was a relationship between hippocampal BDNF expression and resilience to chronic stress. (Taliaz, 2011)
Neurotransmitters dopamine and serotonin are also known for their roles in many neurological disorders. Dopamine plays a large role in arousal, …show more content…

The article examination of Zamperini’s social support system and lifestyle focuses on points that have been found in research to be associated with resilience. For instance, it explains how Zamperini had a strong support system growing up, during his entrapment, and in his recovery. As explained previously, support systems help to promote resilience. In addition, it describes how Zamperini was exposed to bullying at a young age. This point of information is important, because it would have provided stress inoculation for Zamperini, preparing him for future …show more content…

David Cox touches on the main focuses of research and emphasizes alternative approaches to the study of resilience. He includes many examples as well as quotes to support his states. The article makes sure to touch on a major factor in the study of resilience, neuropeptide Y and the amygdala. However, the article’s statement that the research data in this field is ambiguous and it has not been completely determined to play a role almost takes back what it said, and downplays the importance of NPY. Most research supports the anti-stress actions of the neuropeptide. It also states that genetic treatment is far off, but intranasal NPY delivery and NYP Y2 receptor antagonists are currently being developed and tested. (Sah, 2012)
David Cox succeeds at discussing the study of resilience. The article does a good job at analyzing the new perspective on PTSD. David Cox presents the information in an orderly fashion, and uses quotes to make his information credible. Cox’s information was relevant and the key facts to study resilience. There is still a lot about the brain that is left to be discovered. It is clear that resilience is a very important process to human survival, and with further research, scientists will become closer to understanding
