(A) Eleven functional connections were associated with the continuity of spontaneous thoughts for somatosensory awareness (red), auditory mental imagery/inner language (green), and visual mental imagery (blue). These connections were identified from the 2^nd half time series data of the decreasing links. Spheres represent the centroids of the Automated Anatomical Labeling Template regions as estimated by the BrainNet Viewer⁷⁰. (B) Participants in the higher percentage group (orange) exhibited more negative functional connectivity in the majority of links relative to the lower percentage group (blue). Functional connectivity was estimated from the 2^nd half of the time series data. (C) Functional connectivity significantly decreased from the 1^st half (blue) to the 2^nd half (orange) of the time series data. Error bars denote standard errors.
