Abstract：
BACKGROUND: Motor inhibition is a complex cognitive function regulated by specific brain regions and influenced by the activity of the Central Autonomic Network. We investigate the two-way Brain-Heart interaction during a Go/NoGo task. Spectral EEG ϑ, α powerbands, and HRV parameters (Complexity Index (CI), Low Frequency (LF) and High Frequency (HF) powers) were recorded.
METHODS: Fourteen healthy volunteers were enrolled. We used a modified version of the classical Go/NoGo task, based on Rule Shift Cards, characterized by a baseline and two different tasks of different complexity. The participants were divided into subjects with Good (GP) and Poor (PP) performances.
RESULTS: In the baseline, CI was negatively correlated with α/ϑ. In task 1, the CI was negatively correlated with the errors and α/ϑ, while the errors were positively correlated with α/ϑ. In task 2, CI was negatively correlated with the Reaction Time and positively with α, and the errors were negatively correlated with the Reaction Time and positively correlated with α/ϑ. The GP group showed, at baseline, a negative correlation between CI and α/ϑ.
CONCLUSIONS: We provide a new combined Brain-Heart model underlying inhibitory control abilities. The results are consistent with the complementary role of α and ϑ oscillations in cognitive control.

摘要：
背景：运动抑制是一种复杂的认知功能，由特定的大脑区域调节，并受中枢自主网络活动的影响。我们研究了Go/NoGo任务期间的双向脑-心相互作用。频谱脑电图，α频带,和HRV参数(复杂性指数(CI)，记录低频(LF)和高频(HF)功率)。
方法：纳入14名健康志愿者。我们使用了经典Go/NoGo任务的修改版本，基于规则移位卡，以基线和不同复杂性的两个不同任务为特征。参与者被分为表现良好（GP）和较差（PP）的受试者。
结果：在基线中，CI与α/呈负相关。在任务1中，CI与误差和α/呈负相关，而误差与α/呈正相关。在任务2中，CI与反应时间呈负相关，与α呈正相关，误差与反应时间呈负相关，与α/呈正相关。GP组显示，在基线，CI和α/之间呈负相关。
结论：我们提供了一种新的脑-心脏组合模型，其具有抑制控制能力。研究结果与α和振荡在认知控制中的互补作用一致。
