Ex Recovery System
Stanford report, 01 February 2006 have fear of pain I prefer suffers Tracie route totii react differently to pain. What are the causes that this variant is the subject of debate - because someone patch you forgot is, exactly, migraine. But a study published in the January issue of the journal pain, shows that the fear and the fear of pain may explain much of the individual differences in pain makes us feel. This study has a strong enough impact, said Sean Mackey, MD, PhD, Assistant Professor of anesthesia and co-author of the study. If we can learn to control the fear of pain, perhaps to help Americans better pain control. The study is the first to show really considering the influence of the fear and anxiety to the experience of pain to the brain. Technology of functional magnetic resonance imaging, traces of brain activity and is used for pain, since the late 90 s estudio-investigadores were able to identify the areas of the brain responsible for fear and anxiety related to physical pain. I can say that as medical pain, that they fear the No. 1 problem that takes in everything, in order to help people better manage their chronic pain, says Mackey. I am interested to do this study because I have great anxiety and fear to believe, an important role in the way in which we perceive the pain and how we perceive the pain otherwise. To study these relationships, the researchers in various psychological tests administered to his subjects have begun to define individual fear. The first, the anxiety sensitivity index questionnaire measured levels of topics of concern about how different physical sensations of palpitations or stomach pain. Measures, for example, if it could be interpreted mid stomach pain, she had stomach cancer or had eaten only a bad lunch pizza. Second, the fear of pain, measured by the questionnaire of anxiety for the different types of physical pain, that it is part of a document to a displacement of the range. Participants not have been applied at different levels of pain on their forearms with a heat tema-sonda hot enough to damage the little comfortable fabric. While the pain was administered, the researchers collected images of the brain of his subjects. The researchers then correlated partitions questionnaire with brain activity in certain regions of the brain. The study found a strong correlation between fear of the questionnaire of pain and right orbital frontal cortex, a region of the brain that once activated can be taken into account to assess the attempts made by fearful individuals or limit responses to pain. He was also a strong correlation between the anxiety sensitivity index and the intermediate area of the prefrontal gyrus of the brain with attention focused on or reflection on the body itself. In other words, is the ex recovery system login the region, looking for things that are false. The correlations were incredibly strong, co-author, said Kevin Ochsner, former Stanford researcher now Assistant Professor of psychology at Columbia University. Surprising to all of us. The researchers noted that there are differences in the perception of pain among people and these individual differences of different fears and anxieties that may be associated with pain. It is only the first step in the work, perhaps you want to consider this issue, said Ochsner, who is convinced that additional research for a better understanding of fear and its relationship can cause pain. We want to know how people use cognitive strategies to make neutral, what was once very negative, said Ochsner. What are the systems of the brain and psychological processes which help to deactivate the painful experiences. .
