Gamma’s absolute power change over 8 neurofeedback sessions

A: Conscious learning curve for one of the subjects using specific mental strategies during neurofeedback training. Neither linear nor quadratic trends are significant; B: Unconscious learning curve for the subject using no specific mental strategy during neurofeedback training. Both linear and quadratic trends are significant, while the quadratic trend line shows better fitting. Solid lines indicate a linear trend and dashed lines quadratic trend.
