The neural correlate of consciousness is defined as the minimal set of neuronal events that gives rise to a specific aspect of a conscious percept (Crick, 2004; Crick and Koch 2003; Tononi and Koch, 2015). Yet, the connection between consciousness science and other subdisciplines of cognitive neuroscience has been unfairly The neural correlates of consciousness have been defined as the minimal neural mechanisms that are together necessary and sufficient for experiencing any conscious percept (Crick and Koch, 1990).
