Perhaps they are, but what does that tell you?

Note that you'd also have to be somewhat more precise as to what the "state" and "next state" are. It is likely that the state is everything that enters the brain (i.e. by means of sensing, such as what we see, hear, feel, introspect, etc.). However, parts of this state enter the brain at various places and at various frequencies. Abstracting that all away might be problematic.
