Spontaneous Modulation of Standard EEG Frequency Bands During a Neurofeedback-Like Task.

ABSTRACT: Widely used to treat cognitive, affective, psychiatric, and neurological disorders, electroencephalographic neurofeedback (EEG-NF) provides individuals with real-time feedback of their EEG activity to modify brain function. However, the mechanisms behind the EEG changes targeted by EEG-NF remain unclear. The present study addresses this gap by examining methodological issues in the assessment of spontaneous EEG changes during EEG-NF sessions. Over multiple trials, healthy young adults observed a gray circle that either remained constant (control condition) or was continuously modified in size at different frequency rates (1, 5, and 10 Hz). We investigated whether EEG frequency bands classically targeted by EEG-NF: (i) change spontaneously over time, (ii) are influenced by a continuously mo
