Brain sciences April 24, 2021 Davide Sattin, Francesca Giulia Magnani, Laura Bartesaghi et al.
A scoping review of 68 articles published between 2007 and 2017 analyzed 29 theories of consciousness. The theories showed heterogeneous perspectives, with the most variability concerning subjectivity, neural correlates of consciousness (NCC), and the relationship between consciousness and cognitive function. Among sub-cortical structures, the thalamus, basal ganglia, and hippocampus were most frequently indicated; among cortical areas, the cingulate, prefrontal, and temporal regions, as well as the thalamo-cortical system, were most reported. The review also identified multiple definitions of consciousness and 21 new sub-classifications.
