Sparse temporal sampling has become the dominant paradigm for functional magnetic resonance imaging studies of auditory stimuli or verbal responses, as it allows the presentation or production of stimuli during the relatively quiet periods ...
Regularity and randomness in ageing: Differences in resting-state EEG complexity measured by largest Lyapunov exponent [0.03%]
老化过程中的规律性和随机性：由最大lyapunov指数测量的静息状态EEG复杂度差异
Matthew King-Hang Ma,Manson Cheuk-Man Fong,Chenwei Xie et al.
Matthew King-Hang Ma et al.
The loss of complexity in ageing hypothesis (LOCH) has found support from EEG studies, most of which adopted signal-domain complexity measures. The present study adopted the largest Lyapunov exponent (LLE) to measure complexity from a nonli...
Investigating the brain regions involved in tDCS-Enhanced category learning using finite element modeling [0.03%]
利用有限元模型研究tDCS增强类目学习相关的脑区

Transcranial direct current stimulation (tDCS) influences performance in many cognitive domains. However, the question of which brain networks are involved in these effects is rarely examined. In prior experiments we identified tDCS protoco...
No evidence for changes in GABA concentration, functional connectivity, or working memory following continuous theta burst stimulation over dorsolateral prefrontal cortex [0.03%]
持续θ节律经颅磁刺激背外侧前额叶后谷氨酰胺浓度、功能连接或工作记忆未发生变化：一项随机对照试验
Tribikram Thapa,Joshua Hendrikse,Sarah Thompson et al.
Tribikram Thapa et al.
Continuous theta burst stimulation (cTBS) is thought to reduce cortical excitability and modulate functional connectivity, possibly by altering cortical inhibition at the site of stimulation. However, most evidence comes from the motor cort...
The human dorsal hippocampal commissure: Delineating connections across the midline using multi-modal neuroimaging in major depressive disorder [0.03%]
抑郁症患者海马缰束的连接：多模态影像学研究
Anurag Nasa,Caoimhe Gaughan,Muhammad Mahmoud et al.
Anurag Nasa et al.
Reclining on the lyra of the fornix, the dorsal hippocampal commissure (DHC) facilitates communication between the left and right hippocampi. Despite being a key commissural fiber bundle of the hippocampus, the DHC remains relatively undere...
Fiber tract integrity in patients with brain injury and chronic health symptoms [0.03%]
脑损伤和慢性健康症状患者的纤维束完整性
Xiaojian Kang,John P Coetzee,Keith L Main et al.
Xiaojian Kang et al.
Patients with traumatic brain injuries (TBI), especially those with chronic health symptoms, often experience behavioral impairments attributable to white matter (WM) microstructural degeneration. Diffusion tensor imaging (DTI) is sensitive...
No change in electrocortical measures of performance monitoring in high trait anxious individuals following multi-session attention bias modification training [0.03%]
多阶段注意力偏向修正训练对高特质焦虑个体的脑电性能监测指标无影响
Joshua M Carlson,Lin Fang,Jeremy A Andrzejewski
Joshua M Carlson
Heightened attentional bias to threat and enhanced performance monitoring have been linked to higher levels of anxiety. Attentional bias modification (ABM) was developed to reduce attentional bias to threat and thus reduce anxiety. Previous...
Behavioral and electrocortical effects of transcranial alternating current stimulation during advice-guided decision-making [0.03%]
经颅交流电刺激在建议指导决策过程中的行为和脑电皮层效应

In decision-making with uncertain outcomes people may rely on external cues, such as expert advice, even if this information has no predictive value. While the fronto-parietal event-related potential (ERP) components feedback-related negati...
Revisiting the effective connectivity within the distributed cortical network for face perception [0.03%]
面孔感知分布式皮层网络内有效连接性的再探究
Roman Kessler,Kristin M Rusch,Kim C Wende et al.
Roman Kessler et al.
The classical core system of face perception consists of the occipital face area (OFA), fusiform face area (FFA), and posterior superior temporal sulcus (STS). The functional interaction within this network, more specifically the effective ...

Sandeep R Panta et al.
When aggregating neuroimaging data across many subjects, an important consideration is establishing some group-level uniformity prior to further statistical analysis. Spatial normalization and motion correction are two important preprocessi...
