This study aimed to investigate brain signal complexity associated with superior putting performance in expert golfers. Fifty expert golfers (handicap = −2.8 ± 3) each performed 60 putts at a distance of 10 feet. Putting performance was categorized as either a successful or unsuccessful putt (SP vs. UP), based on whether the ball was holed. Electroencephalography (EEG) was recorded during the motor preparatory period (−2 to 0 s) preceding swing onset. Multiscale Entropy (MSE) analysis was employed to quantify EEG signal complexity across six electrode sites: Fz, Cz, Pz, Oz, T3, and T4. Results revealed significantly higher neural complexity for SP compared to UP at Pz (scales 12, 15–17, 19, 21–25) and Oz (scales 20, 22, 25), but significantly lower complexity at T3 (scales 20, 23, and 24). These findings suggest that the involvement of long-timescale integrative processes of visuospatial regions, alongside reduced neural complexity in verbal-analytic regions may characterize optimal putting performance states. Supplemental cortical connectivity analyses further support the MSE findings, demonstrating that superior putting performance was associated with reduced cortical–cortical communication between T3 and midline regions (i.e., Fz, Cz, and Pz). The present findings advance previous EEG research by moving beyond traditional linear analytic methods and align with the psychomotor efficiency hypothesis, which proposes that superior cognitive-motor performance is supported by more refined neural states that enhance task-relevant processing while minimizing interference from task-irrelevant activity. This study suggests that MSE may serve as a valuable neural indicator of the mechanisms underlying optimal cognitive-motor performance in precision sports.

本研究旨在探讨专业高尔夫球手优异推杆表现与大脑信号复杂性的关系。50名专业高尔夫球手（差点= -2.8±3）每人在10英尺的距离上推杆60次。推杆成绩根据球是否进洞分为成功推杆和不成功推杆（SP vs. UP）。在摆动开始前的运动准备期（-2 ~ 0）记录脑电图（EEG）。采用多尺度熵（MSE）分析量化Fz、Cz、Pz、Oz、T3和T4六个电极位置的脑电信号复杂性。结果显示，SP在Pz（量表12、15-17、19、21-25）和Oz（量表20、22、25）的神经复杂性显著高于UP，但在T3（量表20、23和24）的神经复杂性显著低于UP。这些发现表明，视觉空间区域的长时间整合过程的参与，以及语言分析区域神经复杂性的降低，可能是最佳推杆表现状态的特征。补充的皮质连通性分析进一步支持了MSE的发现，表明优异的推杆表现与T3和中线区域（即Fz， Cz和Pz）之间的皮质-皮质通讯减少有关。目前的研究结果超越了传统的线性分析方法，并与精神运动效率假说相一致，从而推动了之前的脑电图研究。精神运动效率假说提出，卓越的认知运动表现是由更精细的神经状态支持的，这些神经状态可以增强任务相关的加工，同时最大限度地减少任务无关活动的干扰。本研究提示MSE可作为精确运动中最佳认知运动表现机制的有价值的神经指标。

Consciousness remains a multifaceted phenomenon that is difficult to be measured by traditional quantification methods. Here we propose the intrinsic probability density function (iPDF) as a quantitative method to evaluate the dynamic inter-cortical interactions that underlie conscious states. First, the method utilizes empirical mode decomposition to derive intrinsic mode functions (IMFs) from EEG signals. Then, the method generates scale-dependent probability density functions for successive partial sums of IMFs that can capture subtle variations in neural modulation patterns. We tested the iPDF analysis across various consciousness states such as general anesthesia, distinct sleep stages (wakefulness, REM, and deep sleep), sensory conditions (eyes open versus eyes closed), and between dementia patients and healthy subjects. Our findings reveal that active neural interactions or modulations during wakefulness and REM sleep are characterized by super-Gaussian iPDF patterns. By contrast, the reduced interactions observed in anesthesia and deep sleep yield near-Gaussian iPDF profiles. We also present a classification model built on iPDF features that achieved an accuracy of approximately 87 % in distinguishing dementia patients from health controls, demonstrating the iPDF as a potential biomarker in clinical screening. This study supports the idea that consciousness emerges from complex, scale-dependent neural processes and presents a robust, quantitative framework that may enhance both our theoretical understanding and practical assessment of various states of consciousness.

意识仍然是一个多方面的现象，很难用传统的量化方法来衡量。在这里，我们提出了内在概率密度函数（iPDF）作为一种定量方法来评估作为意识状态基础的动态皮质间相互作用。首先，该方法利用经验模态分解从脑电信号中导出固有模态函数（IMFs）。然后，该方法为IMFs的连续部分和生成尺度相关的概率密度函数，可以捕获神经调制模式的细微变化。我们在各种意识状态下测试了iPDF分析，如全身麻醉、不同的睡眠阶段（清醒、快速眼动和深度睡眠）、感觉状态（睁眼和闭眼），以及痴呆患者和健康受试者之间的iPDF分析。我们的研究结果表明，在清醒和快速眼动睡眠期间，活跃的神经相互作用或调节具有超高斯iPDF模式的特征。相比之下，在麻醉和深度睡眠中观察到的相互作用减少产生接近高斯的iPDF分布。我们还提出了一个基于iPDF特征的分类模型，该模型在区分痴呆患者和健康对照方面的准确率约为87%，证明iPDF是临床筛查中的潜在生物标志物。这项研究支持了意识从复杂的、依赖于尺度的神经过程中产生的观点，并提出了一个强大的、定量的框架，可以增强我们对各种意识状态的理论理解和实际评估。

The gut microbiota and its metabolites have been implicated in anxiety-like behavior in preclinical models. Recent correlational evidence in humans has linked fear learning with the abundance of specific bacterial taxa, suggesting that bacterial metabolites such as short-chain fatty acids (SCFAs) may act as gut-brain signaling mediators. Using a human fear conditioning paradigm, we initially analyzed data from 146 healthy male participants and found that interindividual differences in the circulating SCFA butyrate—but not acetate or propionate—were associated with physiological threat-safety discrimination during fear acquisition, as measured by skin conductance responses. However, a replication analysis in an independent sample of 71 participants found no such association. A post-hoc pooled analysis across all participants (N = 217) suggested that butyrate was linked with the magnitude of threat-safety discrimination, but only in individuals with at least minimal physiological discrimination (n = 165). These preliminary correlational findings require further confirmation, including causal investigations into butyrate’s potential epigenetic role in modulating memory- and plasticity-related genes.

在临床前模型中，肠道微生物群及其代谢物与焦虑样行为有关。最近在人类中的相关证据表明，恐惧学习与特定细菌分类群的丰富程度有关，这表明细菌代谢物，如短链脂肪酸（SCFAs）可能起着肠-脑信号介质的作用。使用人类恐惧条件反射范式，我们最初分析了来自146名健康男性参与者的数据，发现循环SCFA丁酸酯（而不是醋酸酯或丙酸酯）的个体间差异与恐惧获得期间的生理威胁-安全歧视有关，这是通过皮肤电导反应测量的。然而，在71名参与者的独立样本中进行的重复分析没有发现这种关联。一项针对所有参与者（N = 217）的事后汇总分析表明，丁酸盐与威胁-安全歧视的程度有关，但仅适用于至少具有最小生理歧视的个体（N = 165）。这些初步的相关发现需要进一步的证实，包括对丁酸盐在调节记忆和可塑性相关基因中的潜在表观遗传作用的因果调查。

Research of neural oscillations has shifted from studying individual frequency components to within-cycle modulation and interactions between components. Deciphering these complexities requires advanced methodological approaches capable of accurately capturing the dynamical nature of biological signals. Conventional methods such as event-related potentials and time-frequency spectral analyses assume stationarity, linearity, and additive processes, overlooking nonlinear and nonstationary features of brain activity. Cognitive insights from traditional techniques are therefore limited, potentially misrepresenting how transient oscillatory events contribute to cognition. Critical issues inherited from analytical methods include: First, predefined frequency bands obscure inter-individual and task-dependent variations, including shifts in individual alpha frequency. Second, focus on sinusoidal waveforms neglects functional relevance of nonsinusoidal oscillatory shapes encoding critical physiological information. Third, Fourier-based methods assume linear superposition of oscillations, but multiplicative interactions are prevalent in natural systems. Therefore, Fourier methods may overlook critical nonlinear interactions and misinterpret underlying mechanisms. To address these limitations, we propose Holo-Hilbert Spectral Analysis (HHSA) as a unified framework for analyzing neurophysiological signals. This approach utilizes empirical mode decomposition (EMD) to extract intrinsic mode functions (IMFs) directly from data. By applying additional EMD to envelope and instantaneous frequency functions, researchers can quantify energy from multiplicative and phase-based processes. The approach offers three advantages: First, IMF extraction provides objective signal analysis adapting to individual characteristics without predetermined frequency boundaries. Second, waveform shape and nonlinearity can be described with frequency modulation spectrum. Third, signal envelope modulation can be quantified using amplitude modulation spectrum, helping identify potential cross-frequency couplings.

神经振荡的研究已经从研究单个频率分量转向研究周期内调制和分量之间的相互作用。破译这些复杂性需要能够准确捕捉生物信号动态特性的先进方法。传统的方法，如事件相关电位和时频分析假设平稳性、线性和加性过程，忽略了大脑活动的非线性和非平稳性特征。因此，传统技术的认知见解是有限的，可能会歪曲瞬态振荡事件对认知的贡献。从分析方法继承的关键问题包括：首先，预定义的频带模糊了个体之间和任务相关的变化，包括个体α频率的变化。其次，关注正弦波形忽略了编码关键生理信息的非正弦振荡形状的功能相关性。第三，基于傅里叶的方法假设振荡的线性叠加，但乘法相互作用在自然系统中普遍存在。因此，傅里叶方法可能忽略了关键的非线性相互作用，并误解了潜在的机制。为了解决这些限制，我们提出了Holo-Hilbert谱分析（HHSA）作为分析神经生理信号的统一框架。该方法利用经验模态分解（EMD）直接从数据中提取固有模态函数（IMFs）。通过将额外的EMD应用于包络和瞬时频率函数，研究人员可以量化乘法和基于相位的过程的能量。该方法具有三个优点：首先，IMF提取提供了适应个体特征的客观信号分析，没有预定的频率边界。其次，可以用调频频谱来描述波形形状和非线性。第三，信号包络调制可以使用调幅频谱量化，有助于识别潜在的交叉频率耦合。

This study seeks to assess the applicability of EEG spectral biomarkers in application fields where cognitive characterization is required, e.g. Virtual Reality, User Experience Assessment (UXA), and Ergonomics. It aims to gauge users' cognitive states across varying task settings. We have gathered EEG data from three distinct datasets for this purpose. The first dataset encompasses EEG recordings from 36 participants under two conditions: at rest and while performing arithmetic operations. Additionally, participants were categorized as skilled or unskilled performers, making this dataset valuable for evaluating the effectiveness of different EEG features related to working memory. The second dataset comprises EEG data from 14 participants memorizing different quantities of characters (specifically, 2, 4, 6, or 8 characters) for three seconds. This dataset aims to replicate and assess how the identified biomarkers can distinguish between various levels of working memory within the same participant. The third dataset involves EEG recordings from 27 participants engaged in a 90-minute Virtual Reality (VR) driving task, wherein they needed to maintain the car within the lane amid random deviations. This dataset serves the purpose of evaluating the descriptors' capacity to differentiate between states of high and low attention, as measured by their values before lane deviations. It also facilitates an exploration of how fatigue and time-on-task impact these markers. Our findings indicate that the Theta-to-Alpha ratio (TAR) measured at midline electrodes or as the ratio of frontal theta to parietal alpha effectively characterizes cognitive effort during mental arithmetic and memory tasks. In contrast, the Theta-Alpha-to-Beta Ratio (TA2BR) measured at temporal scalp locations emerges as the most efficient descriptor for assessing heightened vigilance states, particularly in tasks requiring external attention and rapid responses, such as the VR driving task. The influence of time-on-task on descriptor reliability varied depending on participants' performance levels.

本研究旨在评估脑电图谱生物标志物在需要认知表征的应用领域的适用性，例如虚拟现实，用户体验评估（UXA）和人体工程学。它旨在衡量用户在不同任务设置下的认知状态。为此，我们从三个不同的数据集中收集了EEG数据。第一个数据集包括36名参与者在两种情况下的脑电图记录：休息时和进行算术运算时。此外，参与者被分类为熟练或不熟练的表演者，这使得该数据集对于评估与工作记忆相关的不同EEG特征的有效性很有价值。第二个数据集包括14名参与者在三秒钟内记忆不同数量字符（具体来说是2、4、6或8个字符）的脑电图数据。该数据集旨在复制和评估已识别的生物标志物如何区分同一参与者的不同工作记忆水平。第三个数据集涉及27名参与者的脑电图记录，他们参与了90分钟的虚拟现实（VR）驾驶任务，其中他们需要在随机偏差的情况下将汽车保持在车道内。该数据集的目的是评估描述符区分高注意力和低注意力状态的能力，通过它们在车道偏差之前的值来衡量。它还有助于探索疲劳和完成任务的时间如何影响这些标记。我们的研究结果表明，在中线电极测量的θ - α比值（TAR）或额叶θ与顶叶α的比值有效地表征了心算和记忆任务中的认知努力程度。相比之下，在颞部头皮位置测量的Theta-Alpha-to-Beta比率（TA2BR）是评估高度警惕性状态的最有效描述，特别是在需要外部关注和快速反应的任务中，例如VR驾驶任务。任务时间对描述信度的影响取决于参与者的表现水平。

Using the event-related potential (ERP) method combined with the monetary incentive delay task and arrow Flanker Task, this study investigated the impact of varying punishment anticipation on inhibitory control processing in individuals with test anxiety. Results revealed that during the cue processing, compared to individuals with low test anxiety (LTA), individuals with high test anxiety (HTA) exhibited more negative cue-N2 and CNV amplitudes under high punishment conditions. In the inhibitory control processing, under high punishment conditions, HTA individuals showed more negative N2 amplitudes in incongruent trials compared to LTA individuals. Under no-punishment conditions, HTA individuals demonstrated more positive P3 and conflict SP amplitudes in incongruent trials. The study suggests that excessive punishment anticipation for failure consequences may constitute the mechanism underlying inhibitory control deficits in individuals with HTA. These findings provide a new perspective for understanding the inhibitory control deficits in HTA and offer foundations for targeted interventions.

本研究采用事件相关电位（ERP）方法，结合货币激励延迟任务和箭头侧克任务，研究了不同惩罚预期对考试焦虑个体抑制控制加工的影响。结果表明，在线索加工过程中，与低测试焦虑（LTA）个体相比，高测试焦虑（HTA）个体在高惩罚条件下表现出更多的负线索- n2和CNV振幅。在抑制控制加工中，在高惩罚条件下，HTA个体比LTA个体在不一致试验中表现出更多的负N2波幅。在非惩罚条件下，HTA个体在不一致试验中表现出更多的正P3和冲突SP幅值。研究表明，对失败后果的过度惩罚预期可能构成HTA个体抑制控制缺陷的机制。这些发现为理解HTA的抑制控制缺陷提供了新的视角，并为有针对性的干预提供了基础。

Cognitive plausibility of count-based versus prediction-based word embeddings: A large-scale N400 study 基于计数与基于预测的词嵌入的认知合理性：一项大规模的N400研究。

The N400 is a central electrophysiological event-related-potential (ERP) marker thought to reflect meaning comprehension in the human brain. Typically, the N400 is larger when a word does not fit into a specific context (e.g., I drink coffee with cream and dog). Thus, one core factor determining the N400 amplitude is thought to be the predictability of a word within its context. Here, both long-term memory associations and short-term discourse context influence the N400 amplitude. In the present study, we used the N400 as a marker to investigate the cognitive plausibility of semantic similarity measures. Specifically, we compared traditional count-based measures to modern machine learning tools such as prediction-based word embeddings to assess whether prediction-based techniques potentially encapsulate learning mechanisms that align more closely with psychological plausibility. To do so, we examined the relationship between different similarity measures (LSA, HAL and word2vec) and the N400 amplitude in a large scale re-analysis of previously published EEG data. Model comparison suggested a superiority of HAL over LSA as a predictor in explaining single-trial N400 amplitudes, and also a benefit of prediction-based methods over count-based methods. This result aligns with the notion that such models might in the future provide further insights into how the brain navigates language understanding.

N400被认为是反映人脑意义理解的中心电生理事件相关电位（ERP）标记。通常，当一个词不适合特定的上下文（例如，我喝咖啡加奶油和狗）时，N400会更大。因此，决定N400振幅的一个核心因素被认为是单词在其上下文中的可预测性。在这里，长期记忆关联和短期话语语境都影响N400振幅。在本研究中，我们使用N400作为标记来研究语义相似度量的认知合理性。具体来说，我们将传统的基于计数的度量与现代机器学习工具（如基于预测的词嵌入）进行了比较，以评估基于预测的技术是否潜在地封装了与心理合理性更紧密结合的学习机制。为此，我们对先前发表的脑电图数据进行了大规模重新分析，研究了不同相似性度量（LSA、HAL和word2vec）与N400振幅之间的关系。模型比较表明，HAL优于LSA作为解释单次试验N400振幅的预测因子，并且基于预测的方法优于基于计数的方法。这一结果与这样一种观点相一致，即这种模型可能在未来为大脑如何驾驭语言理解提供进一步的见解。

Across two experiments, we examined the role of phasic cardiac fluctuations – whether the heart contracts (systole) or relaxes (diastole) – on two attentional mechanisms: executive control (EC) and alerting. Empirical evidence for cardiac phase effects in alerting has been missing, and studies on EC have found mixed results. Thus, we disentangled how cardiac fluctuations affect alerting and EC, separately and then together, using a subset of highly validated Attentional Network Test (ANT). EC was probed by requiring participants to resolve a conflict in an incongruent flanker stimulus. The stimulus was presented either during systole or diastole (Experiment 1, n = 48). Next, in Experiment 2 (n = 45), in addition to probing EC, we also probed alerting by providing participants, on half of the trials, with a cue to warn them of the onset of the stimulus. The cue was shown either during systole or diastole. Our results demonstrated that phasic cardiac fluctuations shape the more immediate alerting response to external cues, but not the subsequent executive control over conflicting information. Specifically, a cue that was presented at a time of increased cardiac output (during systole) elicited a more pronounced alerting effect than the same cue presented during diastole. Whether the stimulus appeared during systole or diastole had no impact on EC functioning. Overall, these findings contribute to the growing body of research on the interaction between cardiac signals and cognitive processes, emphasizing the selective role of systolic and diastolic phases in influencing alerting rather than executive control.

在两个实验中，我们检查了阶段性心脏波动——心脏收缩（收缩）还是放松（舒张）——在两种注意力机制中的作用：执行控制（EC）和警报。关于心脏期在警报中的作用的经验证据一直缺乏，对EC的研究发现了不同的结果。因此，我们使用高度验证的注意力网络测试（ANT）的一个子集，分别和一起解开了心脏波动如何影响警报和EC。通过要求被试在不一致的侧侧刺激下解决冲突来探索EC。刺激可在心脏收缩期或舒张期出现（实验1，n = 48）。接下来，在实验2 （n = 45）中，除了探测EC，我们还通过在一半的试验中向参与者提供提示来警告他们刺激的开始来探测警报。该提示在心脏收缩期或舒张期显示。我们的研究结果表明，阶段性心脏波动塑造了对外部线索的更直接的警报反应，而不是对冲突信息的后续执行控制。具体来说，在心输出量增加时（收缩期）出现的提示比在舒张期出现的提示引起的警报效果更明显。无论刺激出现在心脏收缩期还是舒张期，对EC功能均无影响。总的来说，这些发现有助于心脏信号和认知过程之间相互作用的研究，强调收缩和舒张期在影响警报而不是执行控制方面的选择性作用。

Cognitive flexibility is crucial for adaptive human behaviour. Prior studies have analysed the effect of reward on cognitive flexibility; however, the neural mechanisms underlying these effects remain largely unknown. This study explores how reward influences neural oscillations and how these changes impact behavioural performance. Using time-frequency decomposition, we examined electroencephalographic data from participants engaged in rule-guided task-switching with varying reward prospects. Higher anticipated rewards lead to greater desynchronisation of alpha (8–12 Hz) and beta (20–30 Hz) oscillations, which in turn correlated with improved task performance. Both alpha power and event-related potential (ERP) coding of reward independently predicted reward-based performance improvements, suggesting distinct mechanisms supporting proactive control. These findings underscore the unique contributions of neural oscillations in mediating motivational effects on cognitive flexibility.

认知灵活性对于适应性人类行为至关重要。先前的研究分析了奖励对认知灵活性的影响；然而，这些影响背后的神经机制在很大程度上仍然未知。本研究探讨了奖励如何影响神经振荡以及这些变化如何影响行为表现。使用时频分解，我们检查了参与规则引导任务转换的参与者在不同奖励前景下的脑电图数据。更高的预期奖励导致更大的α (8-12Hz)和β (20-30Hz)振荡的不同步，这反过来又与改进的任务表现相关。奖励的α功率和事件相关电位（ERP）编码都能独立预测基于奖励的绩效改善，表明支持主动控制的不同机制。这些发现强调了神经振荡在调节认知灵活性的动机效应方面的独特贡献。

Spatial perspective taking (SPT) is a core cognitive ability essential for real-world navigation, yet the examination of dynamic integration of allocentric and egocentric reference frames using map has received limited attention. To address this gap, the present study introduces a Map-Based Self-Localization Task paired with event-related potential (ERP) techniques to examine how angular disparities and rotation directions affect SPT. High school participants (n = 38) completed 320 Map-Based Self-Localization trials. Behavioral analyses revealed that accuracy and response speed varied significantly with angular disparity, and notably, rotation direction also emerged as a critical factor, with left-turn rotations (South to West, 90°) resulting in significantly lower accuracy compared to equivalent right-turn rotations (South to East, 90°). ERP and oscillatory analyses showed that larger angular disparities elicited stronger neural activation in frontal, central, and parietal-occipital regions, evidenced by elevated delta-band power and increased P300 amplitudes. Lateralized readiness potentials further underscored the role of motor imagery in directional rotations, reinforcing an embodied cognition perspective. These results highlight both angular disparity and rotation direction as important considerations in spatial navigation research using map, with implications for SPT theory.

空间视角获取（SPT）是现实世界导航的一项核心认知能力，但利用地图对非中心和自我中心参照系动态整合的研究却很少得到关注。为了解决这一问题，本研究引入了一个基于地图的自定位任务，并结合事件相关电位（ERP）技术来研究角差异和旋转方向对SPT的影响。高中参与者（n = 38）完成了320次基于地图的自我定位试验。行为分析显示，精度和响应速度随角度差异而显著变化，值得注意的是，旋转方向也是一个关键因素，与等效的右转旋转（从南到东，90°）相比，左转旋转（从南到西，90°）导致的精度显著降低。ERP和振荡分析表明，更大的角度差异引起额叶、中央和顶叶-枕叶区域更强的神经激活，证明了δ波段功率升高和P300振幅增加。侧化准备电位进一步强调了运动意象在定向旋转中的作用，强化了具身认知视角。这些结果强调了角视差和旋转方向是地图空间导航研究的重要考虑因素，并对SPT理论有一定的启示。
