typo: dipole is placed in primary somatosensory cortex!
when recording EEG, the orientation of underlying dipoles will heavily influence what kind of field will be picked up on the sensor level. (single dipole placed in hand knob area of primary motor cortex) pic.twitter.com/cSbk95MLa7

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).
