Neuroimaging research (Raichle, 2015; Fox et al., 2016) confirms that stepping out of goal-directed cognitive tasks disengages the task-positive dorsolateral prefrontal network, allowing medial prefrontal and hippocampal default mode circuits to process emotional valence, synthesize life narrative, and mitigate chronic stress.

1. Current Scientific Consensus

Neuroimaging research (Raichle, 2015; Fox et al., 2016) confirms that stepping out of goal-directed cognitive tasks disengages the task-positive dorsolateral prefrontal network, allowing medial prefrontal and hippocampal default mode circuits to process emotional valence, synthesize life narrative, and mitigate chronic stress.

2. Major Unanswered Scientific Uncertainty

Long-term multi-cohort replication and optimal individualization remain active areas of study.
