Abstract: Several recent reports in large, independent samples have demonstrated the influence of motion artifact on resting-state functional connectivity MRI (rsfc-MRI). Standard rsfc-MRI preprocessing typically includes regression of confounding signals and band-pass filtering. However, substantial heterogeneity exists in how these techniques are implemented across studies, and no prior study has examined the effect of differing approaches for the control of motion-induced artifacts. To better understand how in-scanne… Show more

“…Our findings are partially consistent with the observations of Satterthwaite and colleagues, who reported that motion produces signal decreases throughout the entire brain and that these effects scale with the size of a movement (Satterthwaite et al, 2013). However, these authors also reported that signal depressions were largely complete 2 TRs (6 sec) after a movement.…”

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.

“…As expected, the models with 12 regressors explain more variance than the models with only six regressors. This general trend is consistent with results from previous studies (Satterthwaite et al, 2013b). The results were consistent regardless of the use of either GSR or censoring (Table 2).…”
