Another relevant ( imo ) bit is that we are comparing a " centralized " brain ( humans ) to a " distributed " nervous system that functions like a brain ( jellies, octopi )
The human enteric system is a good example of a distributed nervous system, and it's actually able to function autonomously without the centralized brain
We consider an octopus to be able to " think ", yet it has no centralized brain, so we could attempt to say it's not " conscious " because it lacks a brain, yet somehow we say it " thinks "
This makes me question how we define things, because now we are saying that " thinking " is an emergent property in something that evolved to have no centralized brain
The problem is we are only just learning how to understand how vastly different nervous system patterns can create similar behavioral responses. There is no absolute reason to state that a decentralized nervous system could not become complex enough with sufficient neural plasticity to allow that creature to recognize itself as separate from its environment in both space and in time and draw from sufficient working memory to be conscious. The centralized brain has the advantage of close approximation of the structures that can take sensory information, filter what is needed, couple with memory and integrate all of the sensory information and match to schema that has been developed to make intentional decisions. We are only starting to understand this concept.
