A “cerebro-digital system” is a set of elements of the digital infosphere on the one hand and the brain of living beings on the other hand, which are closely interconnected which makes a cooperative interaction possible to fulfil a function, a purpose or a task, whereby a transspheral functional unit is constituted.

The term “cerebro-digital system” was formed as part of the terminology of the “Digital Era Framework”. In this framework of reference, four spheres are defined on the basis of the type of information manifestation. This scheme can be used to classify systems along those four spheres: The infosphere, which consists of the analog infosphere and the digital infosphere, together with the cognisphere and the entisphere.

Since the spheral classification of the brain depends on the purpose of the analysis, different spheres can be affected: If the physical materiality of the organ is taken into account, it concerns the biosphere and thus the entisphere. If a functional perspective is taken, an involvement of the Cognisphäre is to be noted. The term “cerebro-digital system” refers in particular to systems that establish a direct connection between the brain and the media of the digital infosphere.

The term “cyber-cerebral system” can serve as a synonym for the “cerebro-digital system”.
