Scale-free physiological processes are ubiquitous in the human organism. Resting-state
functional MRI studies observed the loss of scale-free dynamics under anesthesia. In …

The human brain's cerebral cortex exhibits a topographic division into higher‐order
transmodal core and lower‐order unimodal periphery regions. While timescales between …

The brain is continuously bombarded by external stimuli, which are processed in different
input systems. The intrinsic features of these sensory input systems remain yet unclear …

Consciousness is constituted by a structure that includes contents as foreground and the
environment as background. This structural relation between the experiential foreground …

Consciousness and its neural mechanisms remain a mystery. Current neuroscientific
theories focus predominantly on the external input/stimulus and the associated stimulus …

Intrinsic brain activity is characterized by the presence of highly structured networks of
correlated fluctuations between different regions of the brain. Such networks encompass …

Electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) studies
revealed that spontaneous activity in the brain has scale-invariant properties, as indicated …

The dynamic and robust characteristics of intrinsic functional connectivity of coherent
spontaneous activity are critical for the brain functional stability and flexibility. Studies have …

Emerging neuroimaging studies emphasize the dynamic organization of spontaneous brain
activity in both human and non-human primates, even under anesthesia. In a recent study …

Which temporal features that can characterize different brain states (ie, consciousness or
unconsciousness) is a fundamental question in the neuroscience of consciousness. Using …
