Neural and behavioral adaptations to frontal theta neurofeedback training: A proof of concept study

FCz full spectrum and topographic maps of theta and alpha power for the first and last training sessions for each group during NF.
Topographic maps of mean theta (4–7 Hz; top row) and alpha (8–13 Hz; bottom row) averaged over Blocks for Session 1 (left map) and Session 5 (right map) of NF training and corresponding mean power spectra at FCz from 0–30 Hz for INC group (left spectra), ALT group, down-modulation (middle spectra), and ALT group, up-modulation blocks (right spectra).
