Measuring and appraising placebo effects in clinical trials: contemporary challenges and approaches in psychiatry.

The lancet. Psychiatry May 1, 2026 Joseph J Taylor, Balázs Szigeti, Noah D Silverberg et al.

Placebo effects are among the greatest paradoxes in medical research. Although more data on placebos are available from placebo-controlled trials than on any treatment in medicine, there has been comparatively little deep interrogation of issues related to their measurement, appraisal, and interpretation. Most of the work that has been done, including that in psychiatry, is narrowly focused on...

Default Mode Network Functional Connectivity As a Transdiagnostic Biomarker of Cognitive Function.

Biological psychiatry. Cognitive neuroscience and neuroimaging April 1, 2025 Vaibhav Tripathi, Ishaan Batta, Andre Zamani et al. 23 citations

The default mode network (DMN) is intricately linked with processes such as self-referential thinking, episodic memory recall, goal-directed cognition, self-projection, and theory of mind. In recent years, there has been a surge in the number of studies examining its functional connectivity, particularly its relationship with frontoparietal networks involved in top-down attention, executive...

Decoding Mindfulness With Multivariate Predictive Models.

Biological psychiatry. Cognitive neuroscience and neuroimaging April 1, 2025 Jarrod A Lewis-Peacock, Tor D Wager, Todd S. Braver 2 citations

Identifying the brain mechanisms that underlie the salutary effects of mindfulness meditation and related practices is a critical goal of contemplative neuroscience. Here, we suggest that the use of multivariate predictive models represents a promising and powerful methodology that could be better leveraged to pursue this goal. This approach incorporates key principles of multivariate decoding,...

Mindfulness Meditation and Placebo Modulate Distinct Multivariate Neural Signatures to Reduce Pain.

Biological Psychiatry 2025 Gabriel Riegner, Jon G Dean, Tor D Wager et al.

Rather than a passive reflection of nociception, pain is shaped by the interplay between one's experiences, current cognitive-affective states, and expectations. The placebo response, a paradoxical yet reliable phenomenon, is postulated to reduce pain by engaging mechanisms shared with active therapies. It has been assumed that mindfulness meditation, practiced by sustaining nonjudgmental...

Default mode network anti-correlation as a transdiagnostic biomarker of cognitive function

April 14, 2024 Vaibhav Tripathi, Ishaan Batta, Andre Zamani et al. preprint

The default mode network (DMN) is intricately linked with processes such as self-referential thinking, episodic memory recall, self-projection, and understanding the mindset of others. Over recent years, there has been a surge in examining its functional connectivity, particularly its antagonistic relationship with frontoparietal networks (FPN) involved in top-down attention, executive...

Neural Signatures of Pain Modulation in Short-Term and Long-Term Mindfulness Training: A Randomized Active-Control Trial

American Journal of Psychiatry July 28, 2022 Joseph Wielgosz, Tammi R. A. Kral, David M Perlman et al. 21 citations

OBJECTIVE: Mindfulness-based interventions are widely used to target pain, yet their neural mechanisms of action are insufficiently understood. The authors studied neural and subjective pain response in a randomized active-control trial of mindfulness-based stress reduction (MBSR) alongside long-term meditation practitioners. METHODS: Healthy participants (N=115) underwent functional...

Effects of compassion training on brain responses to suffering others.

Social Cognitive and Affective Neuroscience September 30, 2021 Yoni K Ashar, Jessica R Andrews-Hanna, Joan Halifax et al.

Compassion meditation (CM) is a promising intervention for enhancing compassion, although its active ingredients and neurobiological mechanisms are not well-understood. To investigate these, we conducted a three-armed placebo-controlled randomized trial (N = 57) with longitudinal functional magnetic resonance imaging (fMRI). We compared a 4-week CM program delivered by smartphone application...

Effects of compassion meditation on a psychological model of charitable donation.

Emotion (Washington, D.C.) August 1, 2016 Yoni K Ashar, Jessica R Andrews-Hanna, Tal Yarkoni et al.

Compassion is critical for societal wellbeing. Yet, it remains unclear how specific thoughts and feelings motivate compassionate behavior, and we lack a scientific understanding of how to effectively cultivate compassion. Here, we conducted 2 studies designed to a) develop a psychological model predicting compassionate behavior, and b) test this model as a mediator of a Compassion Meditation...
