Testing circuit-level theories of consciousness in humans.

Trends Cogn Sci September 20, 2025

Our understanding of the neural basis of consciousness is mostly restricted to large-scale brain activity patterns as measured by methods such as functional magnetic resonance imaging (fMRI) and magneto/electro-encephalography (M/EEG). In contrast, we lack even basic understanding of circuit-level mechanisms supporting consciousness - particularly in humans - despite the fundamental role that...

A complex systems perspective on psychedelic brain action.

Trends Cogn Sci February 3, 2023 Manesh Girn, Fernando E. Rosas, Richard E. Daws et al. 76 citations

Recent findings suggesting the potential transdiagnostic efficacy of psychedelic-assisted therapy have fostered the need to deepen our understanding of psychedelic brain action. Functional neuroimaging investigations have found that psychedelics reduce the functional segregation of large-scale brain networks. However, beyond this general trend, findings have been largely inconsistent. We argue...

Dimensions of Animal Consciousness.

Trends Cogn Sci August 20, 2020 Jonathan Birch, Alexandra K. Schnell, Nicola S. Clayton 394 citations

How does consciousness vary across the animal kingdom? Are some animals 'more conscious' than others? This article presents a multidimensional framework for understanding interspecies variation in states of consciousness. The framework distinguishes five key dimensions of variation: perceptual richness, evaluative richness, integration at a time, integration across time, and self-consciousness....
