A substantially revised version of our paper on periodic & aperiodic activity in WM tasks is now available in eLife. We demonstrate that standard baseline correction in EEG time-frequency representations can mask meaningful aperiodic dynamics during continuous WM maintenance. doi.org/10.7554/eLif...

We have developed a method for time-resolved parameterization of EEG activity into aperiodic and periodic components. We show that what appears as theta in a baseline corrected time-frequency plot may actually be changes in aperiodic activity.
