Neural Noise- A proof-of-concept combines neurofeedback with working-memory training to target neural dynamics in aging.1
- The approach is relevant to neurofeedback and neuromodulation pipelines (medRxiv preprint).1 1

- The source is a medRxiv pilot feasibility study (preprint 2025.10.08.24316788) testing a novel visual neurofeedback protocol that rewards EEG patterns linked to optimal working-memory retrieval in older adults.2
- Only 3 older adults participated, each completing 8-16 neurofeedback sessions, with eyes-closed resting EEG recorded before and after training.2
- The protocol aimed to increase alpha power (associated with focused attention) and reduce delta power (linked to memory lapses); preliminary results suggested a rise in alpha oscillations and a reduction in delta waves, including enhanced occipital (O1/O2) alpha.2
- The design integrated working-memory task performance, EEG-based monitoring of frontoparietal activity, and real-time feedback, seeking EEG markers sensitive to moment-to-moment WM fluctuations suitable for closed-loop feedback.2
- With n = 3 and no control group, the authors frame the work strictly as proof-of-concept feasibility to motivate larger studies rather than as evidence of efficacy.2
- Context: a 2024 meta-analysis of 14 trials (n = 284) found EEG neurofeedback improved working memory (Hedges’ g = 0.665, 95% CI 0.473-0.858) and episodic memory (g = 0.595) in older adults, both moderate effect sizes.3
- Context: that meta-analysis showed benefits were dose-dependent, requiring more than 300 minutes of total training; shorter protocols produced no significant WM gains, and effects held in both healthy and mild-cognitive-impairment subgroups (MCI WM g = 0.812).3
- Context: an earlier randomized placebo-controlled SMR neurofeedback study in 17 older adults improved delayed-match-to-sample working memory in the trained group but not in sham or no-training controls, using 19-channel EEG.4
- Context: a 2026 double-blind RCT (92 adults aged 65-75, 10 sessions) of motor-imagery neurofeedback found no cognitive gains over classical cognitive stimulation, underscoring responder variability and the role of baseline functional-network organization.5
- For neurotech/BCI, the work supports EEG neurofeedback as a low-cost, closed-loop cognitive-training modality for aging, but the overall evidence is mixed and dose-dependent, warranting adequately powered controlled trials.23
