Alzheimer's disease-related changes in regional spontaneous brain activity levels and inter-region interactions in the default mode network [PDF]
, 2013 The degree of Granger causal modeling estimated influence for a brain region was reported to predict its blood oxygenation level-dependent (BOLD) activity level in the resting-state default mode network (DMN).

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.

Abnormal spontaneous brain activity in minimal hepatic encephalopathy: resting-state fMRI study [PDF]
, 2016 PURPOSEWe aimed to assess the abnormality of baseline spontaneous brain activity in minimal hepatic encephalopathy (MHE) by amplitude of low frequency fluctuation (ALFF) and fraction ALFF (fALFF).METHODSA total of 14 MHE patients and 14 healthy controls ...

Sensory memory for odors is encoded in spontaneous correlated activity between olfactory glomeruli [PDF]
, 2006 Sensory memory is a short-lived persistence of a sensory stimulus in the nervous system, such as iconic memory in the visual system. However, little is known about the mechanisms underlying olfactory sensory memory.

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 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.

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
