Sure! In fact, you could say that the eyes are the part of the brain that has a close isomorphism to (a tiny subset of the EM manifestation of) the real world. Once you get about 2-3 cm from the retinas, though, I think that information has been encoded in ways that make it unrecognizable from the outside. I'm saying I doubt we'll ever be able to decode a model (let alone a map) of London from studying a cab driver's hippocampus.
- hackinthebochs 7y agoThis is probably not true. There have been experiments where faces have been reconstructed by measuring the neural responses of monkey's when seeing faces: https://www.bbc.com/news/science-environment-40131242 https://www.bbc.com/news/science-environment-40131242
- carapace 7y agoWow, that's cool! Cheers! I have to adjust me "priors", as a Bayesian might say. Still, monkeys aren't humans, and faces aren't London. Recognizing faces and their expressions has been a thing since faces first evolved, eh?
- hackinthebochs 7y agoPlace cells have recently made the rounds in popular science which are basically the cognitive topological maps being discussed. The fidelity of these maps remain to be seen.
