Power spectral density (PSD) maps obtained from BrainDriver game EEG records in 2019 sessions 15–20. The PSD maps show the logarithmic magnitude for three EEG channels (C3, CZ, C4) that provided a prominent contribution to the control of the BrainDriver in 75 individual games during sessions 15–20 (results from individual games corresponding to the indicated sessions are presented in the horizontal axis). Vertical dotted lines separate session groups 15–16 from 17–18 and 19–20
