This paper introduces a model-free method, Temporal Synchronization Analysis, to detect nonlinear brain activations in fMRI data across multiple cognitive tasks.

This study uses fMRI to compare brain connectivity in meditators and novices during Yoga Nidra, finding distinct DMN decoupling in meditators linked to their practice experience.

The paper investigates DMN dynamics across tasks and finds low synchronization in task-negative regions and weak task-positive regions across subjects and trials.
