More Retrosplenial Cortex stuff. Fascinating to me: Atrophied Retrosplenial Cortex is found in Alzheimer’s Patients but not Dementia. This is fascinating. See, the Retrosplenial Cortex I’m learning holds onto what’s FAMILIAR to you. Places you recognize. Objects you recognize. People you recognize. If the “familiarity circuit” is damaged, everything’s new. Everybody’s new. And lack of familiarity is scary, particularly if you now lack the ability to form familiarity. A substitute Retrosplenial Cortex would solve it. A memory chip of familiarity. But we’re far from that. But someday they’ll figure it out.

Walls, Hallways, Maze navigation, context vs rules, So the Retrosplenial Cortex (RSC) is activated with Permanent sentences but not with Transient sentences. I also learned that Retrosplenial Cortex is likely responsible for translating Egocentric coordinates (Me in relation to other things) coordinates to Allocentric coordinates (Other things in relation to each Other things, ignoring self, grid) and Allocentric to Egocentric. I also learned that while it’s thought of as visual (maze navigation), congenitally blind have no trouble learning and use the V1 system (first level of vision usually) So, probably missing a link or two but makes sense to me, I think permanent as an “Always” and “Never” is Walls and Rules and while you can add new rules, adding TO a rule would be Transient. (Exceptions are adding to existing rules). But you can add new rules that are the consequence of CONDITIONS so that BOTH are always true, always false, one true and one false and in the moment one consciously task switches rather than automatically knowing specific exceptions. Or I think Transient can be easily converted to Permanent at least in language by making Change a constant or Intermittent a quality of a permanent thing. So the Rubbish, the Drummer’s performance dependability and the Climate can have a permanent quality of Change. That could be a way somebody with a deficient or malfunctioning Retrosplenial Cortex can learn to adapt to change: by adopting a permanence of change. I have to flesh this out more as it’s a lot of ‘new’ but I’m getting a bit of a ‘sense’ of it at least.

So, I don’t fully understand this except they successfully found a repeatable method to turn a map projection with height into a playably accurate (not just technically accurate) representation of real earth in minecraft. I think if I reread this a few times it’ll click but I’ll just say that I’m impressed at least by the presentation on this page. “The real world is not flat – on a large scale it’s pretty much ellipsoidal. However, we often want to represent a part of the surface of the Earth on a map (on paper or on a computer screen) – so we use map projections to map from the curved surface of the ellipsoid onto a flat surface (2D). We also agree that our landscape is not really a positively curved, rotationally symmetric ellipsoid. There are hills, valleys, buildings and so on. We get around that with the help of so-called height models, which represent the surface in a coordinate system which is a combination of a flat 2D planar system and a height axis. The height axis can represent height above the ellipsoid, a truly geometric concept, or the height above a geoid, that carries the important geophysical information that water tends to run downhill!” “1.

Love that view. What I’m trying to find I think is where “gut feeling” / “I know it when I see it” / vaguely right would be. It’s a meta … OH!@ it’s “Model Agnostic Meta Learning”. Ok. I think I found it. I dunno, I gotta look at it. I’ll know it when i see if it’s the right one. https://arxiv.org/pdf/1904.05046.pdf

Love that view.
