As simpler for realization ancestor of the DFR Id propose the
following duplex modification of Olds experiment.
Rat-1 can press a key modulating current to stimulate a zone of
positive reinforcement of Rat-2. At the same time Rat-2 can press a
key modulating current to stimulate a zone of positive reinforcement of
Rat-1.
Of course more complex combinations of ensemble of rats and keys are
possible.
May be someone already proposed that? Or try to research that?
