Question about replay & rumination:
Some assume rumination = replay.
But it seems to me that rumination content reaches consciousness but replay need not be.
Does someone study/model that difference?
If rumination = replay + X,
what is X? Conscious, cortex-driven, self-related?
@smfleming Ruminations are often inaccurate and filled with distortions, why would anyone assume rumination = replay? Do unconscious ruminations even exist? (this would defy their definition)
@neurocritic I guess it depends on the definition of replay- if by replay we mean a sequence of decodable internal states, then this could accommodate distortions with respect to world states / veridical memory etc. I agree unconscious rumination doesn’t make much sense. But unconscious replay seems to exist… so interesting to figure out what makes the difference
@smfleming Maybe it's more of a continuum. How much replay is actually veridical?
@neurocritic probably only a small proportion - in the sense that it is an active process of learning / model-building. So it can replay things that have not actually been experienced (as in the neat MEG work by Yunzhe Liu, Tim Behrens and co)
