Dynamic neural circuit disruptions associated with antisocial behaviors

Abstract: Antisocial behavior (ASB) is believed to have neural substrates; however, the association between ASB and functional brain networks remains unclear. The temporal variability of the functional connectivity (or dynamic FC) derived from resting-state functional MRI has been suggested as a useful metric for studying abnormal behaviors including ASB. This is the first study using low-frequency fluctuations of the dynamic FC to unravel potential system-level neural correlates with ASB. Specifically, we individually … Show more

“…We also found an interesting result that rFPN-mVN variation increased after the TMS treatment, which was positively correlated with visuospatial function. Currently, investigating the temporal variability of dFNC is believed to be an effective method to characterize intrinsic temporal fluctuations in functional connectivity and to associate network activities and behaviors [ 35 , 36 ]. The fluctuation in connectivity over time could reflect brain network flexibility, which could be essential for cognitive abilities [ 37 – 39 ].…”

“… 48 Such a soft margin method has been well-validated, extensively used and demonstrated superior performance even with a small sample size. 34 , 35 , 49 Herein, we used a linear kernel with a hyperparameter C = 1 34 , 50 , 51 and other hyperparameters were kept as defaults to make the model more robust, 35 including insensitivity = 0 and an eInsensitive loss function. 34 , 50 , 51 …”

“…Dynamic functional connectivity (dFC), commonly evaluated using sliding temporal windows correction, 21–23 has been adopted to quantify the time‐varying functional connectivity patterns of rs‐fMRI signals across spatially separate brain regions. Previous studies demonstrated that the temporal property of the dFC has been found quite informative in detecting the switch of cognitive states 24 and sensitive to many brain diseases 25,26 .…”
