Not that complex What it shows is how much knowledge they are gaining of understanding the signalling process's of the sense modality of auditory perceptions. What it shows is they are learning how to explain to a computer more and more of the auditory signalling process's of what the auditory sense experiences of getting from point A to point B and branching out to other points of pathways that get utilized. It is not that complex to grasp that in depth research has been going on for quite some time and we only know what they want us to know concerning articles they release vs information they prefer to keep under wraps. But that's just my opinion.
