Successful Single-Session Neural Self-Regulation Through Neurofeedback Varies Between Features

Summary A study of 20 healthy participants who trained self-regulation of four cortical rhythms — frontal midline theta, occipital alpha, unilateral central-temporal sensorimotor rhythm, and central beta — across four neurofeedback sessions found that all could regulate at least two features, but none could regulate frontal midline theta. The authors argue this shows 'non-learners' is not a personal trait that generalizes across features, informing future neurofeedback and BCI training protocol design.

Why it matters As the first intra-subject crossover comparison of neurofeedback learning across cortical rhythms, the study reframes the 'non-learner' as feature-specific rather than a fixed personal trait, a finding that bears directly on how BCI and neurofeedback protocols are designed.

This study, published in Human Brain Mapping, analyzed individual learning trajectories of self-regulating 4 cortical rhythms in 20 healthy subjects across 4 sessions of neurofeedback training, testing frontal midline theta, occipital alpha, unilateral centrotemporal sensorimotor rhythms and central beta in terms of both frequency and spatial selectivity.

All subjects could self-regulate at least 2 of these features, but none succeeded in regulating frontal midline theta; a clustering approach identified two learning dynamics, a linear increase/decrease and a non-linear plateau-like trajectory. The authors say the results offer important insights into the 'non-learner' problem. PMID 42458811, DOI 10.1002/hbm.70611
