There is burgeoning interest in the application of neuroscientific technology to facilitate meditation and lead beneficial psychological outcomes. One popular approach using consumer-grade neurofeedback devices deliver feedback on brain targets during (mindfulness-based neurofeedback). It hypothesized that optimizing like alpha theta band activity may allow meditators experience deeper mindfulness thus This study aimed systematically review meta-analyze impacts mindfulness-based compared with control conditions. Included studies involved practice operationalized as open monitoring or focused attention meditation. was preregistered.

Meditation practices have demonstrated numerous psychological and physiological benefits, yet capturing the neural correlates of varying meditative depths remains challenging. This study aimed to decode self-reported time-varying depth in expert practitioners using EEG. Expert Vipassana meditators (n=34) participated two separate sessions. Participants reported their on a personally defined 1-5 scale both traditional probing novel "spontaneous emergence" method.

Neurofeedback concurrent with mindfulness meditation may reveal effects on the brain and facilitate improved mental health outcomes. Here, we systematically reviewed EEG fMRI studies of neurofeedback (mbNF) followed PRISMA guidelines. We identified 10 reports, consisting 177 unique participants, 9 242 participants. Studies focused primarily downregulating default-mode network (DMN). Although found decreases in DMN activations during neurofeedback, there is a lack evidence for transfer effects, majority did not employ adequate controls, e.g. sham neurofeedback. Accordingly, have been confounded by general task-related deactivation. typically examined alpha, gamma, theta frequency bands, most robust supporting modulation band activity. Both mbNF implemented high fidelity clinical populations. However, benefits established. In general, would benefit from sham-controlled RCTs, as well clear reporting (e.g. CRED-NF).

In this randomized, controlled, and double-blind experiment with a relatively large sample (n = 262), novel technique of audiovisual stimulation (AVS) was demonstrated to substantially improve self-reported mood states by reducing several negative affects, including anxiety depression, enhancing performance on mood-sensitive cognitive tasks. Most the AVS effects were highly similar whether binaural beats present or not regardless duration experience.

Identifying the brain mechanisms that underlie salutary effects of mindfulness, meditation, and related practices is a critical goal contemplative neuroscience. Here we suggest use multivariate predictive models represents promising powerful methodology could be better leveraged to pursue this goal. We describe primary principles approach, including decoding, classification, model-based analyses, all which represent strong departure from conventional mapping approaches. highlight two such research strategies – state induction neuromarker identification provide illustrative examples how these approaches have been used examine central questions in as distinction between internally directed focused attention mind wandering, role mindfulness interventions on somatic pain drug-related cravings. conclude by discussing important issues addressed with future research, key tradeoffs using personalized versus population-based approach modeling.
