When one set of signals (for example, visual processing of a particular object, such as an apple) becomes enhanced and boosted, out-competing other signals, then it becomes strong enough to influence widespread networks around the brain (this is referred to as “ignition”). According to the theory, only one piece of information at a time can gain access to a "global neuronal workspace:" Neuronal signals compete with each other constantly. GWT is a theory originally developed by Bernard Baars and further developed by Stanislas Dehaene and colleagues into a global neuronal workspace theory. Language and cultural evolution have played central roles in the elaboration of human consciousness.Ħ.Attention, and the brain’s internal model or schema of its attentional processes, plays a central role in consciousness, and may explain why people believe consciousness is nonphysical.These differences hinge partly on definitions. There are differing expert opinions on whether consciousness is an illusion, or to what degree.Subjective experience is inaccessible to external observers. Subjectivity is built into the very nature of life: as soon as the first cell evolved there was an inside and an outside, and therefore the beginnings of a subjective-objective divide between the body and the outside world.In humans, the sense of self has a much more developed autobiographical component.
