“…In his review of the literature, Itil (1977) reported that the nonspecific diffuse type and "choppy" pattern is most characteristic of schizophrenia. The choppy pattern, consisting of little or no alpha activity with prominent, irregular fast beta activity has been reported by Gibbs, Gibbs, and Lennox (1938), Davis and Davis (1939), Hill (1957), Kennard and Schwartzman (1957) and Bruck (1964), although Hill (1957) attributed the finding to possible muscle tension. Other investigators reported either a diminishment of alpha alone (Berger, 1937;Finley, 1944;Jasper, 1939;Lemere, 1938) or an increase in fast beta activity (Hill & Donovan, 1950, Itil, 1964, cited in Itil, 1977.…”

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.
