Hey,
In general such notons may be captured within paradigms related to emodiment , enactivism or the extended mind hypothesis. The latter holds the consciousness can be extended even onto interactions with bodies and even devices (like phones).
Still the brain is more or less seen as the central locus of behavior. Of course when you look at complex behaviors of an octopus which is thought to be a function of its peripheral nervous system rather than its central nervous system, one can see that some of the fundamental attributes of behavior could stem from the body (hence embodiment).
