Augmenting Mindfulness Training Through Experience-driven Neurofeedback
Augmenting Mindfulness Training Through Experience-driven Neurofeedback
The overall goal of the proposed study is to develop and test real time neurofeedback (EEG-RTNF) as a tool to augment Mindfulness Based Stress Reduction (MBSR). This study is based on the theoretical model that (1) mind-wandering and self-referential processing are associated with stress, (2) meditation redirects the wandering mind toward present-centered awareness, (3) meditation also decreases activity in hubs of the default mode network (DMN) involved in mind-wandering and self-referential processing, and thus (4) meditation leading to decreased activity in these hubs should lead to reduced stress and improved health and well-being. Milestones include: (1) test whether EEG-RTNF from the PCC during meditation augments MBSR in novices; and (2) test whether MBSR with EEG-RTNF from the PCC leads to real-world outcomes in reduced stress and improved attention.
Mindfulness Based Stress Reduction (MBSR) is an effective intervention for promoting positive cognitive and behavioral changes for improved health. However, MBSR delivery may be suboptimal. Recent work on potential neural mechanisms underlying the meditation practices that are core to MBSR may be utilized to improve MBSR delivery and efficacy. The investigators have shown recently that the posterior cingulate cortex (PCC), a brain region implicated in anxiety, addiction, Alzheimer's, ADHD, and other medical maladies, is selectively deactivated during three meditation practices that are core to MBSR suggesting a central role for the PCC in the neurobiology of MBSR. The investigators have also recently confirmed that PCC deactivation corresponds with the subjective experience of meditation in meditators. The proposed study will use EEG-RTNF from the PCC during meditation as an innovative strategy to augment MBSR and improve outcomes.
The task of mindfulness-the principle component of MBSR-is to maintain attention on and acceptance toward present-moment experience, and to redirect attention to one's immediate experience when it has strayed. This present-centered awareness may be considered a counterpoint to self-referential processing and mind-wandering. Consistent with a role for the PCC in mind-wandering, the PCC is specifically deactivated during three meditation practices (mindfulness of the breath, loving-kindness, and choiceless awareness) in experienced meditators compared to novices). Supporting these findings, a research study. showed that PCC deactivation during meditation correlated with a behavioral measure of attention (the Rapid Visual Information Processing Task, RVIP) in experienced meditators, suggesting that PCC deactivation is associated with improved attention in meditators. Another research study showed that the PCC is deactivated when experienced meditators mindfully view emotional images suggesting that PCC deactivation is associated with emotional stability and enhanced present-moment awareness.
EEG-RTNF is an emerging technology similar to classic biofeedback in which individuals receive moment-to-moment feedback of their brain activity during a particular task, typically by a dynamic visual display (e.g., a graph).
