The entropic brain hypothesis proposes that within upper and lower limits, after which
consciousness may be lost, the entropy of spontaneous brain activity indexes the …

General anesthesia reversibly alters consciousness, without shutting down the brain
globally. Depending on the anesthetic agent and dose, it may produce different …

We present a practical “how-to” guide to help determine whether single-subject fMRI
independent components (ICs) characterise structured noise or not. Manual identification of …

Sleep can be distinguished from wake by changes in brain electrical activity, typically
assessed using electroencephalography (EEG). The hallmark of nonrapid-eye-movement …

Environmental events are processed on multiple timescales via hierarchical organization of
temporal receptive windows (TRWs) in the brain. The dependence of neural timescales and …

A central question in neuroscience is how consciousness arises from the dynamic interplay
of brain structure and function. Here we decompose functional MRI signals from pathological …

Long-term consequences of anesthetic exposure in humans are not well understood. It is
possible that alterations in brain function occur beyond the initial anesthetic administration …

Consciousness is a mental characteristic of the human mind, whose exact neural features
remain unclear. We aimed to identify the critical nodes within the brain's global functional …

Recent studies indicate that spontaneous low-frequency fluctuations (LFFs) of resting-state
functional magnetic resonance imaging (rs-fMRI) blood oxygen level-dependent (BOLD) …

In recent years, specific cortical networks have been proposed to be crucial for sustaining
consciousness, including the posterior hot zone and frontoparietal resting state networks …
