If this is indeed the mechanism then it would have a neurochemical basis...
or don't you believe that information storage involves chemical messengers?

In addition, I would suggest that external cues are very important in
modulating any intrinsic timing mechanisms...

Therefore, I would couple this sort of device with isolation of the individual
in a highly controllable environment (perhaps within their own mind?) in which
external timing cues could be manipulated...
