The peak frequency for visual alpha-oscillations is typically between 8 and 12 Hz. So, a person with a peak frequency of 8 Hz will traverse through 480 up and downs per minute, while a person with a 12 Hz peak will traverse through much more, 720. Will it make a difference? 🤔 pic.twitter.com/N5eJKRL5Tp

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).
