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.

“…The span of time between Margulisbacteria and Cyanobacteria was found to be 0.67 Ga; and between Vampirovibrionia and Cyanobacteria 0.44 Ga (Figure 4f and 5). The latter is a value that is consistent with previous studies using entirely different rationales, datasets and calibrations [8, 9].…”

“…Therefore, according to our clock L and M are evolving on average 4.7 times faster than D1 and D2. This result is nicely within the range suggested by the two independent studies referenced above and confirms that our approach using a single protein produced similar rates of evolution as those computed using a large set of highly conserved concatenated sequences (Magnabosco et al., ; Sanchez‐Baracaldo, ; Shih, Hemp et al., ).…”

“…This scenario, derived from the application of a relaxed molecular clock using a non‐parametric CAT model with flexible boundaries, is in agreement with the recent observations by Shih, Hemp et al. () and other molecular clock studies that placed the divergence of Gloeobacter after the GOE (David & Alm, ; Feng, Cho, & Doolittle, ; Marin, Battistuzzi, Brown, & Hedges, ). In this scenario, assuming that the earliest events in the history of photosynthesis started about 3.5 Ga, the divergence of D1 and D2 is set at about 3.2 Ga.…”
