Objective. Meditation and mindfulness are increasingly recognized as important in improving mental well-being. However, electroencephalography (EEG)-based neurofeedback systems supporting these practices typically fail to generalize to unseen subjects. This study investigates the application of both spatial and spectral alignment to EEG to improve the classification of meditation and rest...

Abstract Objectives Neurofeedback training involves real-time monitoring and self-regulation of neural activity. Neurofeedback training paradigms have been widely employed in the context of meditation. Interestingly, prior research revealed focused attention meditation to be associated with desynchronized, non-harmonic, cross-frequency relationships between alpha and theta rhythms, suggesting...

In recent years, assisting meditation using neuro-feedback applications has become increasingly popular. One key component of such applications is the ability to accurately decode the state of meditation from electroencephalography (EEG) signals in real-time, with as small calibration as possible. This work investigates the problem of cross-subject mindfulness meditation decoding from EEG...

ABSTRACT Objectives The study of neural and visceral oscillatory activities reveals that both subsystems and their interactions influence human cognition. In particular, cardiac and neural changes during self-regulation processes can be studied through a comparison of stress-inducing procedures and meditation practices. Methods In this study, we investigate the characteristic profiles of...

Abstract Neurofeedback and meditation practices are techniques aimed at enhancing awareness and self-regulation. Training of alpha power has been found to increase mindfulness outcomes, and increases in alpha power seem relatively consistent during focused attention meditation practices. Considering the commonalities between these self-regulation techniques, here we examined the trainability of...

ABSTRACT Background Breath-focused meditation is recognized for its potential to enhance autonomic regulation and attentional control. However, most research focuses on the study of isolated physiological domains, limiting the understanding of how neural and cardiorespiratory systems interact dynamically to support self-regulatory processes. Methods EEG, ECG, and respiratory activity were...
