Alzheimer's disease (AD) and Lewy body dementia (LBD) are common neurodegenerative dementias with overlapping clinical presentations, making differential diagnosis challenging. While structural magnetic resonance imaging (MRI) has revealed ...
Acting upon threat: Electrocortical, autonomic, and oculomotor responses in anticipation of avoidable and inevitable threats [0.03%]

Attentive immobility is a defensive state that prepares organisms for adaptive responses to imminent threats. In humans, it has been associated with a multimodal pattern of heart rate bradycardia, elevated skin conductance, freezing of gaze...
Beyond the canonical HRF: Flexible temporal modeling reveals unconstrained BOLD profiles during naturalistic viewing [0.03%]

Naturalistic stimuli, such as movies and narratives, are increasingly used in cognitive neuroscience to map cognitive and affective processes onto brain activity measured with functional MRI (fMRI). Features extracted from movies span multi...
When the inner clock fades: Interoceptive decline and consolidation of phase resetting in cortical rhythms by cardiac events underlie healthy lifespan aging [0.03%]
当内心时钟消逝：内在感知力下降和心脏事件对皮层节律相位重置的巩固导致健康寿命衰老

The brain continuously integrates signals from the external environment along with internal bodily cues to support adaptive cognition and homeostasis. Among these, multiple visceral rhythms, such as respiration, circadian fluctuations, and ...
SUITPy: A Python-based toolbox for the analysis of cerebellar functional and anatomical imaging data across the human lifespan [0.03%]
SUITPy：一个基于Python的工具箱，用于分析人类一生中小脑功能和结构成像数据

Yaping Wang et al.
The human cerebellum plays a central role in motor, emotional, and cognitive functions, and is implicated in many brain disorders. To improve the analysis of functional and anatomical imaging from the cerebellum, we introduce SUITPy, an imp...
Atypical low-frequency and high-frequency neural entrainment to rhythmic audiovisual speech in adults with dyslexia [0.03%]
发育性阅读障碍成人脑网络的异常低频和高频锁相同步功能特征研究——一项视听语音节律刺激诱发的跨模态整合研究

Developmental dyslexia has been linked to atypical neural processing of the temporal dynamics of speech, but there has been disagreement concerning whether faster or slower dynamics are impaired. According to the temporal sampling (TS) theo...
Human risk taking and metabolic state: No credible evidence for desacyl-ghrelin modulation of neural or behavioural effects [0.03%]
人类冒险行为与代谢状态：没有可信证据表明脱酰基 ghrelin 对神经或行为的影响有调节作用

Risk taking has often been proposed to depend on homeostatic systems. However, empirical evidence remains inconsistent, and the underlying mechanisms remain debated. Changes in risky decision-making, which are associated with homeostatic al...

The baboon (Papio) is an invaluable resource within nonhuman primate research, having the advantage of being a cercopithecoid (Old World monkey) with one of the largest brains among non-hominid primates. In order to facilitate comparative d...
Spontaneous activation of cortical somatosensory networks depresses their excitability in preterm human neonates [0.03%]
早产新生儿皮层体感网络的自发激活降低其兴奋性
Kimberley Whitehead,Maria Pureza Laudiano-Dray,Judith Meek et al.
Kimberley Whitehead et al.
The cortical activity of preterm human infants is highly discontinuous, comprising transient high-amplitude bursts separated by periods of relative quiescence. While the functional significance of these bursts is well established, the under...
Memory-related default-executive coupling across the lifespan and associations with changes in cognitive control [0.03%]
生命周期中的记忆相关默认执行耦合及其与认知控制变化的关系
