In addition to the close temporal conjunction between the tPCA and tfPCA factors associated with N1 sink and NVS, the bilateral N1 sink/source dipole pairs of grand mean CSD waveforms for targets corresponded to half-cycle sinusoids of 3.7 Hz, and the distinct sink/source sequence for novels at FCz (peaks at 190 and 285 ms) corresponded to a half-cycle sinusoid of 5.3 Hz, thereby falling well within the dominant delta to alpha low-frequency range captured by the two corresponding ERS factors.
