Neuroimaging in social anxiety disorder -- A meta-Analytic review resulting in a neurofunctional model

Social anxiety disorder is the most common disorder when it comes to anxiety. Through the use of neuroimaging, it was confirmed that there is hyperactivation in the fear areas in relation to social anxiety disorder. The lobes that were activated, specifically are the amygdala, insula, anterior cingulate, and prefrontal cortex. It was found that insular activity is often involved with anxiety. The insula becomes a part of the default-mode-network in humans, especially healthy humans. The introduction of state anxiety might explain why there isn't a significant difference in studies observing social anxiety disorder. The disturbance of normal homeostatic network systems might be similar to an imbalance in heightened emotional arousal and enhanced perception of fear stimuli. The role of the parietal and occipital lobes has a heavy emphasis on anxiety disorders. The meta-analysis study shows that the medical parietal regions play an important role in most anxiety disorders.
