Abstract
Conscious processing is a useful aspect of brain function that can be used as a model to design artificial-intelligence devices. There are still certain computational features that our conscious brains possess, and which machines currently fail to perform those. This paper discusses the necessary elements needed to make the device conscious and suggests if those implemented, the resulting machine would likely to be considered conscious. Consciousness mainly presented as a computational tool that evolved to connect the modular organization of the brain. Specialized modules of the brain process information unconsciously and what we subjectively experience as consciousness is the global availability of data, which is made possible by a nonmodular global workspace. During conscious perception, the global neuronal work space at parieto-frontal part of the brain selectively amplifies relevant pieces of information. Supported by large neurons with long axons, which makes the long-distance connectivity possible, the selected portions of information stabilized and transmitted to all other brain modules. The brain areas that have structuring ability seem to match to a specific computational problem. The global workspace maintains this information in an active state for as long as it is needed. In this paper, a broad range of theories and specific problems have been discussed, which need to be solved to make the machine conscious. Later particular implications of these hypotheses for research approach in neuroscience and machine learning are debated.
Highlights
Conscious processing is a useful aspect of brain function that can be used as a model to design artificial-intelligence devices
Consciousness mainly presented as a computational tool that evolved to integration represents the quality of an organism's consciousness
Specialized consciousness and claims that consciousness is modules of the brain process information unconsciously and identical to a particular type of information, which what we subjectively experience as consciousness is the global availability of data, which is made possible by a non modular global workspace
Summary
There are various models of machine consciousness, each with certain strengths and limitations. Having the data in mind among the immense range of thoughts that can become conscious at a given time, only the ones that are universally available constitute the content of consciousness of an objective world In another hand, consciousness scan be reflexive or spontaneous, in such a way that the cognitive system can monitor its processing and obtain information about itself in a self-referential manner. Our visual system blindly and unconsciously processes the images By this mean, many of the brain’s unconscious computations are rational computations, and unexpectedly any machine that attempts towards objectivity would be submitted to Further study of consciousness in the human brain reveals that subliminal stimuli can induce considerable activity in many human minds, conscious perception is associated with a set of specific signatures. Consciousness is involved in routing information to other processing phases, which allows us to perform random chains of operations [33]
