Beta oscillations are linked to the control of goal-directed processing of sensory information and the timing of motor output. Recent evidence demonstrates they are not sustained but organized into intermittent high-power bursts mediating timely functional inhibition. This implies there is a considerable moment-to-moment variation in the neural dynamics supporting cognition. Beta bursts thus offer new opportunities for studying how sensory inputs are selectively processed, reshaped by inhibitory cognitive operations and ultimately result in motor actions. Recent method advances reveal diversity in beta bursts that provide deeper insights into their function and the underlying neural circuit activity motifs. We propose that brain-wide, spatiotemporal patterns of beta bursting reflect various cognitive operations and that their dynamics reveal nonlinear aspects of cortical processing.

Beta：认知爆发


β 振荡与目标导向的感觉信息处理和运动输出时序的控制有关。最近的证据表明它们不是持续的，而是组织成间歇性的高功率爆发，介导及时的功能抑制。这意味着支持认知的神经动力学存在相当大的时刻变化。因此，β 爆发为研究如何选择性地处理感觉输入、通过抑制性认知操作重塑并最终导致运动动作提供了新的机会。最近的方法进展揭示了β爆发的多样性，为它们的功能和潜在的神经回路活动模式提供了更深入的见解。我们提出，大脑范围内的β爆发的时空模式反映了各种认知操作，并且它们的动态揭示了皮质处理的非线性方面。
