“…The crystal structure is monoclinic, and the unit cell parameters have been determined 1. Studies of oriented PPV films by X‐ray diffraction2, 3 and refractive‐index measurements3, 4 indicate a highly anisotropic structure for an unstretched PPV film. Infrared assignments and some transition moment angles of PPV have been reported 5, 6…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). 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.
