Sabin G Shah, Heide Klumpp, Mike Angstadt, Pradeep J Nathan, K Luan Phan. Amygdala and insula response to emotional images in patients with generalized social anxiety disorder. Journal of Psychiatry & Neuroscience : JPN. Ottawa:Jul 2009. Vol. 34, Iss. 4, p. 296-302 (7 pp.)
I chose this article because I thought t was interesting to learn about the parts of the brain that are activated when dealing with emotional processing. The present article deals with people who suffer from generalized social anxiety disorder and looking at their emotional processing. The amygdala is known to serve functions in emotional processing. The study used eleven patents with generalized social anxiety disorder and eleven healthy control subjects. The participants underwent functional magnetic resonance imaging while viewing sets of emotionally specific pictures. The images were positive, negative and neutral. The results found that participants with gSAD displayed enhanced bilateral amygdale and insula reactivity to negative versus neutral images compared to the healthy control participants. The gSAD group the extent of activation in the amygdale activation was correlated with social anxiety severity. Insula activation was correlated with trait anxiety. The researcher’s findings found that the amygdala and insula responses are hyper- reactive to general emotional images with negative emotional content and that these brain regions. The study shows the importance of studying different parts of the brain and how they affect emotional responses to different stimuli .With more studies into this area will help to better understand how certain types of people respond to things they way they do.
