Global change in brain state during spontaneous and forced walk in Drosophila is composed of combined activity patterns of different neuron classes

eLife, 2023
Movement-correlated brain activity has been found across species and brain regions. Here, we used fast whole brain lightfield imaging in adult Drosophila to investigate the relationship between walk and brain-wide neuronal activity.

Altered spontaneous brain activity in patients with acute spinal cord injury revealed by resting-state functional MRI. [PDF]

PLoS ONE, 2015
Previous neuroimaging studies have provided evidence of structural and functional reorganization of brain in patients with chronic spinal cord injury (SCI). However, it remains unknown whether the spontaneous brain activity changes in acute SCI.

Spontaneous Activity in Primary Visual Cortex Relates to Visual Creativity

Frontiers in Human Neuroscience, 2021
Cognitive and neural processes underlying visual creativity have attracted substantial attention. The current research uses a critical time point analysis (CTPA) to examine how spontaneous activity in the primary visual area (PVA) is related to visual ...

Fractional amplitude of low‐frequency fluctuation changes of specific cerebral regions in patients with toothache: A functional magnetic resonance imaging study

Brain and Behavior, 2023
Background Previous studies have indicated that pain‐related diseases can result in significant functional alterations in the brain. However, differences in spontaneous brain activity in toothache (TA) patients remain unclear.

The Structured Mind at Rest: Low-Frequency Oscillations Reflect Interactive Dynamics Between Spontaneous Brain Activity and a Common Architecture for Task Control

Frontiers in Neuroscience, 2022
The Common Model of Cognition (CMC) has been proposed as a high level framework through which functional neuroimaging data can be predicted and interpreted. Previous work has found the CMC is capable of predicting brain activity across a variety of tasks,

Temporal transitions of spontaneous brain activity

eLife, 2018
Spontaneous brain activity, typically investigated using resting-state fMRI (rsfMRI), provides a measure of inter-areal resting-state functional connectivity (RSFC).

Altered spontaneous brain activity in primary open angle glaucoma: a resting-state functional magnetic resonance imaging study.

PLoS ONE, 2014
BackgroundPrevious studies demonstrated that primary open angle glaucoma (POAG) is associated with abnormal brain structure; however, little is known about the changes in the local synchronization of spontaneous activity. The main objective of this study

Spontaneous Brain Activity Did Not Show the Effect of Violent Video Games on Aggression: A Resting-State fMRI Study

Frontiers in Psychology, 2018
A great many of empirical researches have proved that longtime exposure to violent video game can lead to a series of negative effects. Although research has focused on the neural basis of the correlation between violent video game and aggression, little

Predicting brain evoked response to external stimuli from temporal correlations of spontaneous activity

Physical Review Research, 2020
The relation between spontaneous and stimulated global brain activity is a fundamental problem in the understanding of brain functions. This question is investigated both theoretically and experimentally within the context of nonequilibrium fluctuation ...

Task-Driven Activity Reduces the Cortical Activity Space of the Brain: Experiment and Whole-Brain Modeling. [PDF]

PLoS Computational Biology, 2015
How a stimulus or a task alters the spontaneous dynamics of the brain remains a fundamental open question in neuroscience. One of the most robust hallmarks of task/stimulus-driven brain dynamics is the decrease of variability with respect to the ...
