In view of current scientific knowledge, it seems premature to
hypothesize a qualitative distinction between processes, networks,
and structures involved in abstract processes from those
based on perception, episodic, or procedural memories.
Predictive thought and mental travel strongly rely, at different
levels of consciousness, on past and ongoing sensory input,
bodily information (e.g., interoception), and the results of perceptual
elaboration.
