Yes, I know. That's why I called it a configuration variable.

I think it has more to do with the content itself, and the elasticity and adaptability of neural networks. There is no "up" or "down" with inputs. I learned this when working with a machine vision problem. A model will adapt to the orientation or format of a given input. The orientation itself is never a variable, the network simply doesn't care and adapts to it. If you train a model to recognize input in a given orientation, any other orientation will give a high error rate. If you train the model with _every_ orientation, it will be able to classify inputs that are upside down, sideways, mirrored, etc., all relative to the original orientation.

  Exactly. There is no "upside-down" unless you train one way and then flip it. So I wish people would stop saying "babies see upside-down at first."

    To your point ... FWIW, young kids in cultures where they were carried in all different orientations as infants allegedly would not turn over a picture handed to them "upside down" to look at it - whereas kids who were held more upright as infants would. Presumably the former could make sense of objects in many more orientations. (Somewhat sure this was in Ashely Montegue's treatise on Touch.)

As for 'errors', yes, they are typically signs of trauma or dysfunction along the neurons that go into V1. You can have people that have blindsight or that can't tell faces apart in the upper half of their vision. You can get some pretty tragic stuff. You can also have glaucoma or other 'typical' diseases of the eye. Things like blindspots from welding or lasers. The visual system in healthy people is already a bit odd. You have the foveal blindspot, the differing distribution of rods and cones, the unseeing neurons that do light sensation for melanin production, etc. Really, the whole sensory chain is one giant bag of 'wait, it does that? huh?' https://en.wikipedia.org/wiki/Riddoch_syndrome https://en.wikipedia.org/wiki/Riddoch_syndrome
