Connectome-Based Predictive Modeling of Trait Mindfulness.

Human Brain Mapping 2025 Isaac N Treves, Aaron Kucyi, Madelynn Park et al. 8 citations

Trait mindfulness refers to one's disposition or tendency to pay attention to their experiences in the present moment, in a non-judgmental and accepting way. Trait mindfulness has been robustly associated with positive mental health outcomes, but its neural underpinnings are poorly understood. Prior resting-state fMRI studies have associated trait mindfulness with within- and between-network...

Connectome predictive modeling of trait mindfulness

bioRxiv (Cold Spring Harbor Laboratory) July 14, 2024 Isaac N Treves, Aaron Kucyi, Madelynn Park et al. 1 citation preprint

Abstract Introduction Trait mindfulness refers to one’s disposition or tendency to pay attention to their experiences in the present moment, in a non-judgmental and accepting way. Trait mindfulness has been robustly associated with positive mental health outcomes, but its neural underpinnings are poorly understood. Prior resting-state fMRI studies have associated trait mindfulness with within-...

Slower respiration rate is associated with higher self-reported well-being after wellness training

Scientific Reports September 24, 2023 Tammi R. A. Kral, Helen Y. Weng, Vikramjit Mitra et al. 25 citations

Mind-body interventions such as mindfulness-based stress reduction (MBSR) may improve well-being by increasing awareness and regulation of physiological and cognitive states. However, it is unclear how practice may alter long-term, baseline physiological processes, and whether these changes reflect improved well-being. Using respiration rate (RR), which can be sensitive to effects of...

Long-term Meditation Training Is Associated with Enhanced Subjective Attention and Stronger Posterior Cingulate-Rostrolateral Prefrontal Cortex Resting Connectivity.

Journal of Cognitive Neuroscience August 1, 2022 Tammi R. A. Kral, Regina C Lapate, Ted Imhoff‐Smith et al.

Mindfulness meditation has been shown to increase resting-state functional connectivity (rsFC) between the posterior cingulate cortex (PCC) and dorsolateral prefrontal cortex (DLPFC), which is thought to reflect improvements in shifting attention to the present moment. However, prior research in long-term meditation practitioners lacked quantitative measures of attention that would provide a...

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...

Absence of structural brain changes from mindfulness-based stress reduction: Two combined randomized controlled trials

Science Advances May 20, 2022 Tammi R. A. Kral, Kaley Davis, Cole Korponay et al. 67 citations

Studies purporting to show changes in brain structure following the popular, 8-week mindfulness-based stress reduction (MBSR) course are widely referenced despite major methodological limitations. Here, we present findings from a large, combined dataset of two, three-arm randomized controlled trials with active and waitlist (WL) control groups. Meditation-naïve participants ( n = 218) completed...

Long-term meditation training is associated with enhanced attention and stronger posterior cingulate – rostrolateral prefrontal cortex resting connectivity

bioRxiv (Cold Spring Harbor Laboratory) September 17, 2021 Tammi R. A. Kral, Regina C Lapate, Ted Imhoff‐Smith et al. preprint

Abstract Mindfulness meditation has been shown to increase resting state functional connectivity (rsFC) between the posterior cingulate cortex (PCC) and dorsolateral prefrontal cortex (DLPFC), which is thought to reflect improvements in attention to the present moment. However, prior research in long-term meditation practitioners lacked quantitative measures of attention that would provide a...

Non-replication of structural brain changes from Mindfulness-Based Stress Reduction: Two combined randomized controlled trials

medRxiv June 16, 2021 Tammi R. A. Kral, Kaley Davis, Cole Korponay et al. 2 citations preprint

Abstract Studies purporting to show changes in brain structure following the popular, eight-week Mindfulness-Based Stress Reduction (MBSR) course are widely referenced despite major methodological limitations. Here, we present findings from a large, combined dataset of two, three-arm randomized controlled trials with active and waitlist (WL) control groups. Meditation-naive participants (n=218)...

The Effect of Mindfulness Meditation on Impulsivity and its Neurobiological Correlates in Healthy Adults

Scientific Reports August 19, 2019 Cole Korponay, Daniela Dentico, Tammi R. A. Kral et al. 49 citations

Interest has grown in using mindfulness meditation to treat conditions featuring excessive impulsivity. However, while prior studies find that mindfulness practice can improve attention, it remains unclear whether it improves other cognitive faculties whose deficiency can contribute to impulsivity. Here, an eight-week mindfulness intervention did not reduce impulsivity on the go/no-go task or...

Mindfulness-Based Stress Reduction-related changes in posterior cingulate resting brain connectivity

Social Cognitive and Affective Neuroscience July 1, 2019 Tammi R. A. Kral, Ted Imhoff‐Smith, D. Dean et al.

Abstract Mindfulness meditation training has been shown to increase resting-state functional connectivity between nodes of the frontoparietal executive control network (dorsolateral prefrontal cortex [DLPFC]) and the default mode network (posterior cingulate cortex [PCC]). We investigated whether these effects generalized to a Mindfulness-Based Stress Reduction (MBSR) course and tested for...

Mindfulness Meditation and Psychopathology

Annual Review of Clinical Psychology December 11, 2018 Joseph Wielgosz, Simon B. Goldberg, Tammi R. A. Kral et al. 441 citations

Mindfulness meditation is increasingly incorporated into mental health interventions, and theoretical concepts associated with it have influenced basic research on psychopathology. Here, we review the current understanding of mindfulness meditation through the lens of clinical neuroscience, outlining the core capacities targeted by mindfulness meditation and mapping them onto cognitive and...

Impact of short- and long-term mindfulness meditation training on amygdala reactivity to emotional stimuli.

Neuroimage July 7, 2018 Tammi R. A. Kral, Brianna S. Schuyler, Jeanette A. Mumford et al.

ABSTRACT Meditation training can improve mood and emotion regulation, yet the neural mechanisms of these affective changes have yet to be fully elucidated. We evaluated the impact of long‐ and short‐term mindfulness meditation training on the amygdala response to emotional pictures in a healthy, non‐clinical population of adults using blood‐oxygen level dependent functional magnetic resonance...
