Figure 3. Mechanisms of DMN suppression and network switching.

Figure 3.

(A) The triple-network model posits a central role for the salience network in processing behaviorally relevant external events leading to suppression of the DMN and its altered dynamic temporal interactions with the salience and frontoparietal networks. The ensuing engagement of cognitive control circuit dynamics and network switching shapes DMN function and its indirect role in cognition. (B) Onset latencies of event-related responses in six key cortical nodes of the DMN (yellow bars), salience network (blue bars), and frontoparietal network (green bars) during auditory event segmentation. The right AI and adjoining frontal cortex (labeled rFIC) nodes of the salience network display onsets significantly earlier than frontoparietal and DMN nodes. Adapted from24. (C, D) Net causal outflow (out-in degree) of DMN and salience and frontoparietal networks revealed that the rFIC has a significantly higher net causal outflow than DMN nodes across auditory and visual attention tasks.
