Beta events in granular layer SI LFP from an anesthetized mouse and an awake monkey had waveform features consistent with the human data. (A, Upper) Schematic reproduction of the mean primary current dipole and statistically significant features of the beta event waveform. (Lower) Predicted beta events in the LFP from granular layers, if the current dipole and layer IV LFP events are generated by the same underlying mechanisms, e.g., currents flowing within the deep-layer PN dendrites (Fig. 2). (B, Upper). Examples of 50 unfiltered high-power beta events from layer IV of SI (vibrissa neocortex) in an anesthetized mouse. (Lower) Mean and SD defined and aligned as in the human data. (C) As in B, showing data from layer IV of area 3b in an awake monkey during spontaneous periods. The granular layer beta event waveform from each animal was consistent with the human data (SI Appendix, Table S5; also see SI Appendix, Fig. S5A for definition of layers).
