Beta rhythms are ubiquitous in the motor cortex, and many functional roles were proposed. We recently described a double-dissociation between different beta bands in macaques local field potential (LFP), with low beta (<20Hz) originating in primary motor cortex (M1) and correlating with movement preparation and spontaneous postural dynamics, and high beta (>20Hz) originating in dorsal premotor cortex (PMd) and reflecting spatiotemporal attention (Nougaret et al. 2023, doi:10.1101/2023.03.28.534535). Even within these two bands, individual beta events are highly heterogeneous in their tem
