Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices

Advanced Science, EarlyView.
Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate

Lag Threads Organize the Brain’s Intrinsic Activity [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2015
Significance It is well known that slow intrinsic activity, as measured by resting-state fMRI in a variety of animals including humans, is organized into temporally synchronous networks. The question of whether intrinsic activity contains reproducible temporal sequences has received far less attention.

Intrinsic brain activity alterations in patients with Parkinson’s disease

Neuroscience Letters, 2023
The objective of this study is to explore the brain activity alterations in Parkinson's disease (PD) from the perspectives of neuronal activity, synchronization of neuronal activity, and coordination of whole-brain activity.In this study, we recruited 38 PD patients and 35 matched healthy controls (HCs). We explored intrinsic brain activity alterations

Altered intrinsic brain activity in patients with hepatic encephalopathy

Journal of Neuroscience Research, 2021
Abstract Neuropsychiatric deficits are common in patients with liver cirrhosis (LC), especially in those with hepatic encephalopathy (HE). Previous studies reveal abnormalities in brain activity underlying the neuropsychiatric deficits in LC patients; however, the results are inconsistent. We conducted a meta‐analysis of resting‐state

Altered intrinsic brain activity in patients with CSF1R-related leukoencephalopathy

Brain Imaging and Behavior, 2022
CSF1R-related leukoencephalopathy is an adult-onset white matter disease with high disability and mortality, while little is known about its pathogenesis. This study introduced amplitude of low-frequency fluctuations (ALFF) and regional homogeneity (ReHo) based on resting-state functional magnetic resonance imaging(rsfMRI) to compare the spontaneous ...

Intrinsic Synchronization Analysis of Brain Activity in Obsessive–compulsive Disorders

International Journal of Neural Systems, 2020
Obsessive–compulsive disorder (OCD) is one of the neuropsychiatric disorders qualified by intrusive and iterative annoying thoughts and mental attitudes that are activated by these thoughts. In recent studies, advanced signal processing techniques have been favored to diagnose OCD.

[Intrinsic brain activity with pain].

Schmerz (Berlin, Germany), 2012
Besides the responses to nociceptive stimuli other neural function modes of the brain are necessary to obtain a comprehensive understanding of pain processing in humans. During a resting state without extrinsic stimulation the human brain generates spontaneous low frequency fluctuations of neural activity.

Intrinsic brain activity sets the stage for expression of motivated behavior

Journal of Comparative Neurology, 2005
AbstractResearch in many species has provided increasingly detailed information on relevant, primarily subcortical brain systems supporting the expression of basic appetites and drives. While basic appetites and drives are essential for adaptation and survival in any environment, they are naturally constrained by an organism's inherent biology and ...
