Neurofeedback-Assisted Mindfulness Techniques to Reduce Symptoms of Mental Distress

Summary

Neurofeedback training, based on operant conditioning techniques, involves the measurement and conscious regulation of specific neural parameters through participant-specific feedback. This technique has gained recognition for its role in efficiently altering brain activity. Among its various applications, neurofeedback training is noted for its ability to facilitate meditative practice and enhance stress regulation abilities. However, most neurofeedback studies focus on modulating isolated brainwaves and overlook how brainwaves interact across frequencies. To address this gap, the present study will evaluate an intervention that combines meditation techniques with a novel cross-frequency neurofeedback training to enhance the outcomes of meditative practice for stress regulation.

Previous research has established that brain rhythms exhibit interactive patterns, forming harmonic and non-harmonic relationships to respectively facilitate and preclude cross-frequency coupling. Harmonic relationships are essential for the synchronization of oscillations, a process necessary for coordinating complex neural and physiological activities. In contrast, non-harmonic relationships result in a highly desynchronized state characterized by reduced neural and physiological coordination, typically observed during cognitive restful periods. In this regard, prior studies have demonstrated a link between an increased occurrence of non-harmonic alpha-theta ratios and mindfulness meditation.

Recent research has shown the possibility of upregulating the incidence of non-harmonic alpha-theta ratios during mindfulness meditation in a single-session neurofeedback training context. However, the impact of long-term training on stress regulation abilities remains unclear. The current study addresses this gap by conducting a 10-session neurofeedback training focused on upregulating the incidence of non-harmonic alpha-theta ratios during focused attention meditation. The primary aim of this study is to determine the effectiveness of this training in assisting mindfulness practice and improving stress regulation as assessed by a range of neurophysiological, psychological, and biological outcomes.
