The Impact of Alpha-Neurofeedback Training on Gastric Slow Wave Activity and Heart Rate Variability in Humans.

ABSTRACT:

Introduction

Neuromodulation of cortical brain regions associated with the gut-brain axis may have the potential to modulate gastric function. Previous studies have shown phase-amplitude coupling between the electroencephalogram (EEG) alpha band frequency of the insula (Ins) and gastric slow wave (GSW) activity. This study investigated the first evidence of alpha band EEG-neurofeedback (EEG-NF) training to explore its effects on GSW activity and heart rate variability (HRV).

Methods

A randomized crossover design was employed with 20 healthy participants attending two separate sessions [active-training: uptraining left posterior Insula (LPIns) and active-control: uptraining primary visual cortex (PVC Brodmann area 17)] following the baseline recording period. A 5-min water lo
