Pain can be regulated through different cognitive mechanisms. Two meditation practices were compared during noxious heat: Focused Attention, which may regulate negative affect via sensory gating, and Open Monitoring, which may regulate negative affect through nonjudgmental awareness. Long-term meditators, compared to novices, reported significantly less unpleasantness, but not intensity, of pain while practicing Open Monitoring. No significant effects were found for Focused Attention. This finding highlights a possible regulatory mechanism underlying meditation-based clinical interventions such as Mindfulness-Based Stress Reduction.

A breathing-based meditation called Sudarshan Kriya yoga reduced posttraumatic stress disorder (PTSD) symptoms, anxiety, and respiration rate in male U.S. veterans of the Iraq or Afghanistan wars. Twenty-one veterans were randomly assigned to either the active meditation group or a waitlist control group. The active group showed large reductions in PTSD scores and anxiety symptoms, while the control group did not. Reductions in startle response correlated with reduced hyperarousal symptoms immediately after the intervention and at one-year follow-up. The findings suggest Sudarshan Kriya yoga may be a useful alternative treatment for PTSD.

Mindfulness-based stress reduction (MBSR) reduced neural pain responses in healthy adults compared to an active control program. In a randomized trial with 115 participants, MBSR produced a moderate decrease in the neurologic pain signature (NPS) relative to a health enhancement program (Cohen's d=-0.43) and from before to after the intervention (d=-0.47). Subjective pain unpleasantness also decreased modestly in both MBSR and the active control compared to a waiting list. Long-term meditators reported lower pain than nonmeditators but showed no difference in neural pain signatures. Among long-term meditators, cumulative practice during intensive retreats, but not daily practice, was linked to reduced stimulus-independent pain processing (r=-0.65).

Recent EEG studies on the early postmortem interval suggest the persistence of electrophysiological coherence and connectivity in the brain of animals and humans, reinforcing the need for further investigation of brain activity during the dying process. Under the direction of the Center for Healthy Minds at the University of Wisconsin-Madison, research was conducted in India on a postmortem meditative state (tukdam) cultivated by some Tibetan Buddhist practitioners, in which decomposition is putatively delayed. For healthy baseline and postmortem subjects, resting state EEG, mismatch negativity, and auditory brainstem response data were collected. Living subjects displayed well-defined MMN and ABR responses, but no recognizable EEG waveforms were discernable in any of the tukdam cases.
