Summary
AI-generated from the abstractFocused-attention meditation on the breath reorganizes large-scale brain dynamics by reducing activity in neural networks linked to self-referential and memory-based processing while increasing activity in networks supporting attentional stability and internal monitoring. In 22 experienced practitioners, high-density EEG microstate analysis identified five canonical brain states. Meditation robustly reduced Microstate C, generated in medial and lateral temporal regions including the hippocampus, and increased Microstates D and E, generated in posterior midline regions and frontoparietal networks respectively. These changes suggest that focused-attention meditation downregulates self-referential processing and enhances neural states for attention and internal awareness.

Abstract
Focused-attention meditation provides a tractable model for examining how large-scale brain dynamics support attention and self-regulation. Using high-density EEG microstate analysis, we investigated how focused-attention meditation on the breath (Ānāpānasati) modulates intrinsic brain activity in 22 experienced practitioners, compared with baseline rest and deliberate mental imagery. Five canonical microstate classes (A-E) were identified. Meditation produced a robust reduction of Microstate C across coverage, duration, and occurrence, accompanied by increased presence of Microstates D and E (all Microstate x Condition interactions p < 0.0001). Source localization revealed that Microstate C was generated primarily in medial and lateral temporal regions including the hippocampus and parahippocampal cortex, whereas Microstate D involved posterior midline regions including the posterior cingulate cortex and precuneus, and Microstate E engaged frontoparietal and orbitolimbic networks. Together, these results indicate that focused-attention meditation reorganizes the temporal architecture of large-scale brain dynamics by downregulating microstate patterns associated with self-referential and memory-based processing while enhancing neural states supporting attentional stability and internal monitoring.
