Neural correlates of consciousness
![](https://commons.wikimedia.org/wiki/Special:FilePath/Neural_Correlates_Of_Consciousness.jpg?width=300)
The neural correlates of consciousness (NCC) constitute the minimal set of neuronal events and mechanisms sufficient for a specific conscious percept. Neuroscientists use empirical approaches to discover neural correlates of subjective phenomena. The set should be minimal because, under the assumption that the brain is sufficient to give rise to any given conscious experience, the question is which of its components is necessary to produce it.
