This paper formulates the action of psychedelics by integrating the free-energy principle and
entropic brain hypothesis. We call this formulation relaxed beliefs under psychedelics …

Rhythms are a fundamental and defining feature of neuronal activity in animals including
humans. This rhythmic brain activity interacts in complex ways with rhythms in the internal …

A hallmark of electrophysiological brain activity is its 1/f-like spectrum–power decreases with
increasing frequency. The steepness of this 'roll-off'is approximated by the spectral …

Schizophrenia is a complex neuropsychiatric disorder that is associated with persistent
psychosocial disability in affected individuals. Although studies of schizophrenia have …

Sensory processing deficits, first investigated by Kraepelin and Bleuler as possible
pathophysiological mechanisms in schizophrenia, are now being recharacterized in the …

Time and space are the basic building blocks of nature. As a unique existent in nature, our
brain exists in time and takes up space. The brain's activity itself also constitutes and …

Brain operation is profoundly rhythmic. Oscillations of neural excitability shape sensory,
motor, and cognitive processes. Intrinsic oscillations also entrain to external rhythms …

In the last decade, the brain's oscillatory responses have invaded the literature. The studies
on delta (0.5–3.5 Hz) oscillatory responses in humans upon application of cognitive …

Attention plays a fundamental role in selectively processing stimuli in our environment
despite distraction. Spatial attention induces increasing and decreasing power of neural …

Predicting the timing of upcoming events enables efficient resource allocation and action
preparation. Rhythmic streams, such as music, speech, and biological motion, constitute a …
