While the exertion of mental effort improves performance on cognitive tasks, the neural mechanisms by which motivational factors impact cognition remain unknown. Here, we used fMRI to test how changes in cognitive effort, induced by changes...
Thalamocortical Dynamics during Rapid Eye Movement Sleep in the Mouse Somatosensory Pathway [0.03%]

Rapid eye movement (REM) sleep, also referred to as paradoxical sleep for the striking resemblance of its electroencephalogram (EEG) to the one observed in wakefulness, is characterized by the occurrence of transient events such as limb twi...
Cortical Networks Relating to Arousal Are Differentially Coupled to Neural Activity and Hemodynamics [0.03%]
与觉醒相关的皮层网络在神经活动和血流动力学方面表现出不同的连接性

Even in the absence of specific sensory input or a behavioral task, the brain produces structured patterns of activity. This organized activity is modulated by changes in arousal. Here, we use wide-field voltage imaging to establish how aro...
Neuronal Coupling Modes Show Differential Development in the Early Cortical Activity Networks of Human Newborns [0.03%]

The third trimester is a critical period for the development of functional networks that support the lifelong neurocognitive performance, yet the emergence of neuronal coupling in these networks is poorly understood. Here, we used longitudi...
Linking Cognitive Integrity to Working Memory Dynamics in the Aging Human Brain [0.03%]
工作记忆动态与人类衰老大脑的认知完整性之间的联系

Gina Monov et al.
Aging is accompanied by a decline of working memory, an important cognitive capacity that involves stimulus-selective neural activity that persists after stimulus presentation. Here, we unraveled working memory dynamics in older human adult...
Suspending the Embodied Self in Meditation Attenuates Beta Oscillations in the Posterior Medial Cortex [0.03%]
冥想中的自我意识悬置减弱后部内侧皮层的beta振荡活动

Fynn-Mathis Trautwein et al.
Human experience is imbued by the sense of being an embodied agent. The investigation of such basic self-consciousness has been hampered by the difficulty of comprehensively modulating it in the laboratory while reliably capturing ensuing s...
Distinctive Neurophysiological Signatures of Analgesia after Inflammatory Pain in the ACC of Freely Moving Mice [0.03%]
自由活动小鼠炎症痛后ACC脑区镇痛的神经电生理特征

Preclinical assessments of pain have often relied upon behavioral measurements and anesthetized neurophysiological recordings. Current technologies enabling large-scale neural recordings, however, have the potential to unveil quantifiable p...
Structural Connectivity between Olfactory Tubercle and Ventrolateral Periaqueductal Gray Implicated in Human Feeding Behavior [0.03%]
嗅觉结节和 ventrolateral periaqueductal gray 之间的结构连接与人类摄食行为有关

The olfactory tubercle (TUB), also called the tubular striatum, receives direct input from the olfactory bulb and, along with the nucleus accumbens, is one of the two principal components of the ventral striatum. As a key component of the r...
Synapse-Specific Trapping of SNARE Machinery Proteins in the Anesthetized Drosophila Brain [0.03%]
麻醉果蝇大脑中突触特异性捕获SNARE机器蛋白

General anesthetics disrupt brain network dynamics through multiple pathways, in part through postsynaptic potentiation of inhibitory ion channels as well as presynaptic inhibition of neuroexocytosis. Common clinical general anesthetic drug...
