Hierarchical disruption in the cortex of anesthetized monkeys as a new signature of consciousness loss

Miguel Signorelli, Camilo A.; Uhrig, Lynn; Kringelbach, Morten L.; Jarraya, Béchir; Deco, Gustavo (Elsevier, 2020)

Anesthesia induces a reconfiguration of the repertoire of functional brain states leading to a high function-structure similarity. However, it is unclear how these functional changes lead to loss of consciousness. Here we ...
Macroscopic quantities of collective brain activity during wakefulness and anesthesia

Ponce-Alvarez, Adrián; Uhrig, Lynn; Deco, Nikolas; Signorelli, Camilo Miguel; Kringelbach, Morten L.; Jarraya, Béchir; Deco, Gustavo (Oxford University Press, 2022)

The study of states of arousal is key to understand the principles of consciousness. Yet, how different brain states emerge from the collective activity of brain regions remains unknown. Here, we studied the fMRI brain ...
Signature of consciousness in brain-wide synchronization patterns of monkey and human fMRI signals

Hahn, Gerald; Zamora-López, Gorka; Uhrig, Lynn; Tagliazucchi, Enzo; Laufs, Helmut; Mantini, Dante; Kringelbach, Morten L.; Jarraya, Béchir; Deco, Gustavo (Elsevier, 2021)

During the sleep-wake cycle, the brain undergoes profound dynamical changes, which manifest subjectively as transitions between conscious experience and unconsciousness. Yet, neurophysiological signatures that can objectively ...
