Fig. 2. Overall data analysis approach for identifying anterior insular cortex (AI)-stimulation-induced dynamic decoupling of the salience network (SN) and default mode network (DMN) in rats.

a, b We applied a novel Bayesian switching dynamical systems (BSDS) model to time-series data extracted from individual regions of interest (ROIs) corresponding to putative rat SN and DMN nodes to investigate brain state dynamics, and their temporal properties, associated with feedforward optogenetic stimulation of the AI. c We then examined dynamic changes in activation in each ROI and functional brain circuit connectivity associated with stimulation-related brain states.
