How mental training reshapes the temporal architecture of large-scale brain dynamics and how these mechanisms differ between healthy and clinically vulnerable populations remains poorly understood. Time-averaged neural measures collapse the multi-scale nature of brain activity, obscuring the dynamic processes through which behavioural interventions reorganise hierarchical brain function. Here,...
The default mode network (DMN) is a commonly observed resting-state network (RSN) that includes medial temporal, parietal, and prefrontal regions involved in episodic memory [1-3]. The behavioral relevance of endogenous DMN activity remains elusive, despite an emerging literature correlating resting fMRI fluctuations with memory performance [4, 5]-particularly in DMN regions [6-8]. Mechanistic...
