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).

The zebra finch auditory cortex reconstructs occluded syllables in conspecific song - Nature Communications
Neural mechanisms underlying auditory restoration are not fully understood. Here authors show that, neural populations of the zebra finch in the equivalent of auditory cortex respond to song with deleted syllables as if the missing syllables were actually present, indicating that information about the temporal structure of song is stored in this area. Their findings suggest that the internal model has a generalized representation of species-typical syntax.
