吞咽归因于运动输出和感觉输入的协调。我们假设吞咽可以说明运动神经处理和感觉神经处理之间的差异。八名在口面部皮层安装了颅内电极的癫痫参与者被要求吞下水丸。张嘴和吞咽被视为运动任务，而注水被视为感觉任务。研究了低频和高 γ (HG) 频段 (75–150 Hz) 之间的相位幅度耦合。在与电机相关的 HG 功率增加（爆发）之前出现 α (10–16 Hz)-HG 耦合，在与感觉相关的 HG 爆发期间出现 θ (5–9 Hz)-HG 耦合。与电机相关的耦合的峰值比 HG 功率的峰值早 0.6-0.7 秒。与运动相关的 HG 在 α 振荡的波谷处进行调制，与感觉相关的 HG 幅度在 θ 振荡的峰值处进行调制。这些对比结果可以帮助阐明大脑的感觉运动功能。吞咽有两个方面；感觉输入和运动输出 相位幅度耦合显示运动和感觉神经处理的差异 α 和高 γ 波段之间的耦合发生在运动相关的高 γ 活动之前 θ 和高 γ 波段之间的耦合发生在感觉相关的高 γ 活动期间行为神经科学；感觉神经科学。
Swallowing is attributed to the orchestration of motor output and sensory input. We hypothesized that swallowing can illustrate differences between motor and sensory neural processing. Eight epileptic participants fitted with intracranial electrodes over the orofacial cortex were asked to swallow a water bolus. Mouth opening and swallowing were treated as motor tasks, whereas water injection was treated as a sensory task. Phase-amplitude coupling between lower-frequency and high γ (HG) bands (75–150 Hz) was investigated. An α (10–16 Hz)-HG coupling appeared before motor-related HG power increases (burst), and a θ (5–9 Hz)-HG coupling appeared during sensory-related HG bursts. The peaks of motor-related coupling were 0.6–0.7 s earlier than that of HG power. The motor-related HG was modulated at the trough of the α oscillation, and the sensory-related HG amplitude was modulated at the peak of the θ oscillation. These contrasting results can help to elucidate the brain's sensory motor functions. Swallowing has two aspects; sensory input and motor output Phase-amplitude coupling showed differences of motor and sensory neural processing Coupling between the α and high γ band occurred before motor-related high γ activities Coupling between the θ and high γ band occurred during sensory-related high γ activities Neuroscience; Behavioral neuroscience; Sensory neuroscience.
