Closed-Loop BCI Neurofeedback Amplifies Brainwaves to Boost Micro-Error Awareness in 5 Days
DrKavner · x · 2026-09-16
A new study shows a non-invasive brain-computer interface that decodes the elusive Error Positivity (Pe) EEG signature in real time and displays visual confirmation whenever the brain fires it. Over a 5-day training window, Pe wave amplitude steadily grew: traditional behavioral training failed to improve perception of tiny cursor-trajectory rotations, while closed-loop neurofeedback structurally amplified the brain's internal error-detection system — pointing to a safe, non-pharmacological way to boost human precision.
