This is how I think, exactly this (first pic)
Except in my head I use the over activated default-mode network to remember each and every one of them with voices on a loop that I can set the same as DeadMau5 with a sampling pad.
It's the same thing just in sound form. I use visuals just to connect the loops as groups, branches, cells hence the TOWN SQUARE metaphor. Imagine the sounds in a tridimensional space that resembles (and yes it is a place) any rectangular town square with the town hall in the centre where the scheduler control who's turn is next.
That's what having these 3 is for me 馃憞
