Dave -
Are you thinking of the hypothetical explanation based on subthreshold
stimulation of a neural net storing an episodic memory ?? That the situation
one finds oneself in is similar in sensorium to a previous event stored in
memory. The neurons encoding those similarities are stimulated, others in the
neural net (unrelated to the present situation) may also be activated via
spread of depolarization, but not enough of the neurons in the net encoding
the stored event are stimulated to be able to distinguish the past from the
present conditions.
Sorry - no references readily available. . . (maybe I'm just making it up !)
Hope this helps a bit.
