The planning and execution of an efficient motor plan is essential to everyday cognitive function, and relies on oscillatory neural responses in both the beta (14-30 Hz) and gamma (>30 Hz) bands. Such motor control requires not only the integration of salient information from the environment, but also the inhibition of irrelevant or distracting inputs that often manifest as forms of cognitive interference. While the effects of cognitive interference on motor neural dynamics has been an area of increasing interest recently, it remains unclear whether different subtypes of interference differentially impact these dynamics. We address this issue using magnetoencephalography and a novel adaptation of the Multi-Source Interference Task, wherein two common subtypes of cognitive interference are each presented in isolation, as well as simultaneously. We find evidence for the subtype-invariant indexing of cognitive interference across a widely distributed set of motor regions oscillating in the beta range, including the bilateral primary motor and posterior parietal cortices. Further, we find that superadditive effects of cognitive interference subtypes on behavior are paralleled by gamma oscillations in the contralateral premotor cortex, and determine that these gamma oscillations also predict the superadditive effects on behavior.

Beta 和 gamma 振荡索引了分布式运动网络中的认知干扰效应

高效运动计划的规划和执行对于日常认知功能至关重要,并且依赖于 beta (14-30 Hz) 和 gamma (>30 Hz) 波段的振荡神经反应。这种运动控制不仅需要整合来自环境的显着信息,还需要抑制通常表现为认知干扰形式的不相关或分散注意力的输入。虽然认知干扰对运动神经动力学的影响最近越来越受到关注,但尚不清楚不同亚型的干扰是否对这些动力学有不同的影响。我们使用脑磁图和多源干扰任务的新改编来解决这个问题,其中两种常见的认知干扰子类型分别单独或同时呈现。我们发现了跨广泛分布的一组在 beta 范围内振荡的运动区域的认知干扰的亚型不变索引的证据,包括双侧初级运动和后顶叶皮质。此外,我们发现认知干扰亚型对行为的超加性效应与对侧运动前皮层中的伽马振荡平行,并确定这些伽马振荡也预测了对行为的超加性效应。
