************************
Hopfield networks require much more functionality than simple logic gates.
Storing of a vector requires an iterative update of all 1/2(n(n-1))
connections between the n nodal points of a Hopfield network according to
'Heb's rule'.

You have an explanation/function for non-coding DNA?

You don't know if you don't read it!

That is a different story; the mind is indeed a complex phenomenon. I have
only (tried to) tackle an (important) part of its functionality.
