Amygdala Case Study
Measurements of brain and hormone activity in PTSD patients can help inform Western medical treatments, psychotherapy and Chinese Medicine alike. Aside from the impact on pharmacological studies, brain activity can provide insight into new therapies like EMDR and neurofeedback. Clinical studies regarding the biological mechanisms of acupuncture indicate that that acupuncture may be of particular use. (Hollfield 2007)

Amygdala
Overwhelmingly, the amygdala shows an increase in reactivity, mostly right sided, during a triggered state or re-experience of trauma. The amygdala is part of the limbic system and is located deep in the temporal lobes. The right side amygdala regulates aspects of fear and memory. Fear is a productive emotion when one is in danger, as the impulse to fight or flee could be lifesaving. But if one is safe and still firing off fear signals, this can be counterproductive for emotional and physical health. Likewise, the fire alarm that echoes through a building at the slightest hint of smoke or steam from the stovetop – may cause more harm than good. (Bremner 2007) …show more content…
It inhibits the stress response and emotional reaction as it links up with the amygdala. In PTSD patients, activity in the mPFC is diminished; so that the mPFC is not able to adequately “quiet” the stress response. The mPFC is also the reasoning, rational mind. Fire? Where? Let’s find it and put that out. No fire? Let’s deactivate that annoying alarm. In a PTSD patient, the fire is always raging – even when it’s not. (Bremner

    The limbic system is responsible for emotions, survival instincts, and memory and includes structures such as the hippocampus. The amygdala is in control of the perception of anger, fear, sadness, aggression, storing memory of events and emotions, and decision making. This allows for organisms to recognize similar events in the future and heighten awareness for such events (William 2013).…

    The Role of the Amygdala Gaba Receptors and Benzodiazepines in Anxiety

    Discussed is some of the research that has been conducted on the role of the amygdala in anxiety, as well as the role of GABA and benzodiazepines in anxiety. Research has indicated through amygdala lesions and stimulation that the amygdala does indeed play a major role in the expression of anxiety. Research has also indicated, through drug infusions to the amygdala, that benzodiazepines cause anxiolysis (by increasing GABA transmission), and that benzodiazepine antagonists increase anxiety (by decreasing GABA transmission). Also discussed are some limitations and problems found with benzodiazepine use.…

    According to Butcher, Mineka, and Hooley (2013), Post-Traumatic Stress Disorder (PTSD), is a “disorder that occurs following an extreme traumatic event, in which a person re-experiences the event, avoids reminders of the trauma, and exhibits persistent increased arousal”. An example may be, a person who observed or experienced something extremely frightening, may feel that their life or the life of others may be in danger (Butcher, Mineka, and Hooley, 2013). People with PTSD may feel frightened and feel that they don’t have control over their feelings.…

    Amygdala

    We have many different levels of thinking. Some of the things that we do in our lives, such as breathing, walking, blinking, etc become almost instinctive and we really do not have to think much about them. Some things require more thought, such as deciding what to eat, or what to wear for a particular occasion. There are even higher levels of thinking and these include our critical thinking abilities. Many scholars have noted that critical thinking is more of a skill than a process and it mainly consists of evaluating arguments. It is a purposeful, self-regulatory judgment which results in interpretation, analysis, evaluation, and inference, as well as explanations of the evidential, conceptual, methodological, or contextual considerations upon which the judgment is based (Astleitner 2002). In general, "critical thinking" is a mental activity of evaluating arguments or propositions and making judgments that can guide the development of beliefs and taking action. It has also been found that experts from economy and education nominated critical thinking as the most important skill in knowledge management (Astleitner 2002).…

    Accountability Formation

    The dictionary states that the meaning of the word accountability is “the state of being accountable, liable, or answerable”. This means to me that if I don’t hold accountability for all my gear than I am not doing my duty as a soldier. Holding accountability for my gear is important for many different reasons in fact. For one if anything were to happen to my gear I am held sole responsible for it. Also if it is stolen or ruined for my lack of accountability and due to my actions the company is held back from doing their duties or even I completing mine, I would also be the one held accountable for the hold back. If the gear was stolen I would need to pay for it and it wouldn’t be anyone else’s fault except my own, even if it were simply damaged I would need to replace and/or fix as swiftly as possible to complete my duties so that I am not the one holding back others. Specially with it coming so close to leaving on a mission it is crucial that I hold exceptional accountability for my gear for I would not want to be the sole reason for a glitch in the mission before even leaving, with everyone working so hard to get ready to leave and to have everything in working condition in order for the mission to hopefully go off without a hitch. Being accountable for my gear is to be dependable. Being dependable in keeping track of all my gear so that I am ready for anything that would be needed of me at any time, rather it’s from my country, my superiors, or my fellow soldiers. It is also crucial for me to hold accountability for my gear being a specialist I am setting an example for other soldiers below me and for me not to hold that accountability it doesn’t make me look like a very good role model to look upon in time of need, for any reason. Showing accountability is also a duty for me as a soldier to keep track of all of my gear. If my equipment was taken they could of tampered with the gear and then given it back with me not…
