How The Triune brain and The Affective Neuroscience Scale corresponds to the RDoC system. According to the RDoC system, behavioural endophenotypes attribute 5 main behavioural domains. They are not only distinct but describe personality as an interacting and dynamic individual trait. The domains are objectively different, determined by particular neuronal networks. Separation of the networks is due to a distinction in the functions they serve (The Affective Neuroscience Scale, Panksepp, 1998). This distinction corresponds well with the concept of a gradual evolution of the brain (the triune brain model of MacLean, 1970).
