Along similar lines, given the real-time imaging capability of PET and
MRI, is there any work investigating reward mechanisms in cognition?
For example, an implant providing positive reinforcement on recognition
of a target mental state ought to habituate that mental state.  Thus
apes, or humans, could be conditioned to spend the majority of their
conscious time in, say, a problem solving state or a learning state.
