      abstract     = {Beta oscillations observed in motor cortical local field
                      potentials (LFPs) recorded on separate electrodes of a
                      multi-electrode array have been shown to exhibit non-zero
                      phase shifts that organize into planar waves. Here, we
                      generalize this concept to additional classes of salient
                      patterns that fully describe the spatial organization of
                      beta oscillations. During a delayed reach-to-grasp task we
                      distinguish planar, synchronized, random, circular, and
                      radial phase patterns in monkey primary motor and dorsal
                      premotor cortices. We observe that patterns correlate with
                      the beta amplitude (envelope): Coherent planar/radial wave
                      propagation accelerates with growing amplitude, and
                      synchronized patterns are observed at largest amplitudes. In
                      contrast, incoherent random or circular patterns are
                      observed almost exclusively when beta is strongly
                      attenuated. The occurrence probability of a particular
                      pattern modulates with behavioral epochs in the same way as
                      beta amplitude: Coherent patterns are more present during
                      movement preparation where amplitudes are large, while
                      incoherent phase patterns are dominant during movement
                      execution where amplitudes are small. Thus, we uncover a
                      trigonal link between the spatial arrangement of beta
                      phases, beta amplitude, and behavior. Together with previous
                      findings, we discuss predictions on the spatio-temporal
                      organization of precisely coordinated spiking on the
                      mesoscopic scale as a function of beta power.},
