Functional geometry of the brain that encode consciousness
Functional geometry of the cortex encodes dimensions of consciousness Zirui Huang, George A. Mashour & Anthony G. Hudetz January 2023 - Nature Communications DOI: 10.1038/s41467-022-35764-7 Introduction Consciousness has been defined conventionally by two separable components: awareness of the environment and the self (i.e., the content of consciousness) and wakefulness (i.e., level of consciousness). For example, patients with unresponsive wakefulness syndrome (UWS)can maintain eye-opening and sleep–wake cycles but are presumably unaware of themselves and their surroundings; thus, their condition is classified as wakefulness without awareness. The traditional approach to understanding consciousness frequently fails to link specific brain regions to specific functions. The prefrontal cortex, for example, is involved in many functions, such as working memory, decision-making, attention, and task control. A single brain network can be involved in multiple cognitive processes at the
