Conscious experiences are linked to activity in our brain: the neural correlates of consciousness (NCC). Empirical research on these NCCs covers a wide range of brain activity signals, measures, and methodologies. In this paper, we focus on spontaneous brain oscillations; rhythmic fluctuations of neuronal (population) activity which can be characterized by a range of parameters, such as...
What sorts of brain processes covary with consciousness? We argue that empirical neural correlates of consciousness (NCCs) include neural substrates (actual conscious experience representation in the brain), neural prerequisites and neural consequences of a conscious experience. In a conventional correlative paradigm, these three NCCs are principally indistinguishable. However a multi-pronged...
In the search for neural correlates of consciousness (NCC), the concept of 'consciousness' remains problematic. We suggest that not only the 'consciousness' in neural correlates of consciousness is a confused term, but 'correlates' is as well. When brain events are found to covary with conscious experience, these brain events can be the neural substrates of the experience, as is often...
