Psychedelics are increasingly explored as tools to investigate consciousness and cognition, and as potential treatments for mood disorders. While neuroimaging has been central to characterizing their mechanisms of action, the interpretation of these studies may be confounded by the neurovascular effects elicited by the...

Focal brain lesions are thought to induce sleep-like slow-wave activity in perilesional cortex through altered excitation-inhibition balance and structural disconnection, but whether these dynamics extend to remote yet structurally intact regions remain unclear. Here we combined source-reconstructed high-density EEG (1...

A non-invasive framework based on generative whole-brain models of non-equilibrium brain dynamics reveals a robust empirical link between PCI and non-equilibrium dynamics in spontaneous brain signals, suggesting that non-equilibrium dynamics capture an important aspect of perturbational complexity.

Dysfunctional disorders of consciousness are characterized not simply by loss of hierarchical organization but by prolonged stabilization within recurrent hyper-hierarchical brain states, potentially restricting the dynamical repertoire available for conscious processing.

Experiences in which the sense of the body becomes distorted offer a unique window into how the brain constructs the bodily self. Despite their clinical relevance in conditions such as depersonalization and body-image disorders, large-scale brain dynamics underlying unusual bodily experiences (UBEs) remain poorly under...
