For content-specific NCC, experimentscan be carefully designed to systematically investigate possibledissociations between the experience of particular conscious con-tents and the engagement of various cognitive processes, such asattention, decision-making, and reporting (Aru et al., 2012; Kochand Tsuchiya, 2012; Tsuchiya et al., 2015; Tsuchiya and Koch,2016).

Several complementary methods can be used to distill the trueNCC. For the full NCC, within-state paradigms can be used toavoid confounds due to changes in behavioral state and taskperformance as well as to dissociate unconsciousness from unre-sponsiveness

The full NCC can be definedas the union of all content-specific NCC (Koch et al., 2016a).

scious percept (Crick and Koch, 1990). Content-specific NCCare the neural mechanisms specifying particular phenomenalcontents within consciousness, such as colors, faces, places, orthoughts.

The neural correlates of consciousness (NCC) are defined as theminimal neural mechanisms jointly sufficient for any one con-

imaging the brain of an individual who claims to generatejoy without any external rewards or cues could point the waytoward improved training in joy and greater resilience in theface of external difficulties. Of particular interest is the neuralmechanisms by which happiness is generated.
