I kind of hypothesized this in the past. But instead of merely individual and unrelated agents, an agent spawns a new string/tree of neurons/agent after it has been primed for a specific set of inputs. This also means that an object can be represented by many agents and these agents are used to decide which of them is used to predict/classify an object through consensus.
On another related topic, if the brain is operating at quantum level then it might be that these multiple agents are simply superposition of itself.
