oscillations and ERPs often feel like separate worlds, but in some ways, they are different sides of 1 coin. according to the baseline shift account, late ERPs arise because of the non-zero mean property of oscillations, which change their power in the presence of stimuli. pic.twitter.com/uvgXkGJ8d2

ok, imagine you have an oscillation that is not symmetric around 0 (small direct current shift) with some amplitude modulation, for instance with 1/f-dynamics. ➡️ then these 1/f-dynamics will show up in low frequency part of spectrum (red); in addition to around oscillation peak (yellow).
