      abstract     = {Identifying the neural correlates of consciousness (NCCs)
                      is key to support the different scientific theories of
                      consciousness. NCCs can be defined to reflect either the
                      brain signatures underlying specific conscious content or
                      those supporting different states of consciousness, two
                      aspects traditionally studied separately. In this paper, we
                      introduce a framework to characterize NCCs according to
                      their dynamics in both the 'state' and 'content' dimensions.
                      The two-dimensional space is defined by the NCCs' capacity
                      to distinguish the conscious states from non-conscious
                      states, (x-axis) and the content (perceived versus
                      unperceived, y-axis). According to the sign of the x and
                      y-axis, NCCs are separated into four quadrants in terms of
                      how they distinguish the state and content dimensions. We
                      implement the framework using three types of EEG NCCs:
                      markers of connectivity, markers of complexity, and spectral
                      summaries. The NCC-state is represented by the level of
                      consciousness in 1) patients with disorders of
                      consciousness; 2) healthy participants’ during a nap. On
                      the other hand NCC-content by the conscious content in
                      healthy participants' perception tasks: 1) auditory
                      local-global paradigm and 2) visual awareness paradigm. In
                      both cases, we see separate clusters of NCCs with correlated
                      and anti-correlated dynamics, shedding light on the complex
                      relationship between the state and content of consciousness
                      and emphasizing the importance of considering them
                      simultaneously. This work presents an innovative framework
                      for studying consciousness by examining NCC in a
                      two-dimensional space, providing a valuable resource for
                      future research, with potential applications using diverse
                      experimental paradigms, neural recording techniques, and
                      modeling investigations.},
