Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

We believe that several mechanisms are [26]. Among many previous studies, only a few have reported several recurrence cases [4][5][6][7][8][9][10]. Our literature review shows that previous researchers may have missed progression in many cases reported as "without progression" due to individual differences in bevacizumab sensitivity, short follow-up times after bevacizumab is discontinued, or death shortly after bevacizumab is discontinued. …”Section: Discussionmentioningconfidence: 76%
