Modulating spontaneous brain activity using repetitive transcranial magnetic stimulation

BMC Neuroscience, 2010
Background When no specific stimulus or task is presented, spontaneous fluctuations in brain activity occur. Brain regions showing such coherent fluctuations are thought to form organized networks known as 'resting-state' networks, a main representation ...

Spontaneous and evoked activity patterns diverge over development

eLife, 2021
The immature brain is highly spontaneously active. Over development this activity must be integrated with emerging patterns of stimulus-evoked activity, but little is known about how this occurs.

Altered spontaneous brain activity patterns in patients with neovascular glaucoma using amplitude of low‐frequency fluctuations: A functional magnetic resonance imaging study

Brain and Behavior, 2021
Background Neovascular glaucoma (NVG) can cause irreversible visual impairment and abnormal spontaneous changes in brain's visual system and other systems. There is little research on this aspect at present.

Altered temporal dynamics of brain activity in patients with generalized tonic-clonic seizures.

PLoS ONE, 2019
Generalized seizures engage bilateral networks from their onset at a low temporal scale. Previous studies findings have demonstrated focal/local brain activity abnormalities in the patients with generalized tonic-clonic seizures (GTCS).

Altered spontaneous brain activity in patients with hemifacial spasm: a resting-state functional MRI study. [PDF]

PLoS ONE, 2015
Resting-state functional magnetic resonance imaging (fMRI) has been used to detect the alterations of spontaneous neuronal activity in various neurological and neuropsychiatric diseases, but rarely in hemifacial spasm (HFS), a nervous system disorder. We

Brain activity during the preparation and production of spontaneous speech in children with persistent stuttering

NeuroImage: Clinical, 2023
Speech production forms the basis for human verbal communication. Though fluent speech production is effortless and automatic for most people, it is disrupted in speakers who stutter, who experience difficulties especially during spontaneous speech and ...

Altered spontaneous activity in anisometropic amblyopia subjects: revealed by resting-state FMRI. [PDF]

PLoS ONE, 2012
Amblyopia, also known as lazy eye, usually occurs during early childhood and results in poor or blurred vision. Recent neuroimaging studies have found cortical structural/functional abnormalities in amblyopia.

Spatial dynamics of spontaneous activity in the developing and adult cortices

Neuroscience Research
Even in the absence of external stimuli, the brain remains remarkably active, with neurons continuously firing and communicating with each other. It is not merely random firing of individual neurons but rather orchestrated patterns of activity that ...
