From: Effects of gratitude meditation on neural network functional connectivity and brain-heart coupling
Experimental procedure (A). The order of experiments (set I and II) were counter balanced across participants. Illustration for how to evaluate the temporal synchronization between dynamic functional connectivity and heart rate (HR) during the interventions (B–E). Raw time courses and illustration of the sliding-windows for HR (B) and fMRI time series (D). Strategies to compute the temporal correlation between dynamic HR (C) and dynamic FC (E). Abbreviations: RS-fMRI, resting-state functional MRI; PPG, photoplethysmography.
