Neuroscience PhD here. We haven’t got a fucking clue. We have some very general ideas about what kinds of mechanisms it might involve (it might have something to do with changing the strengths of connections between brain cells), but that’s like saying hard drives work by changing the magnetization of bits of metal.. sure, that may be the operational principle, but I still don’t know how a whole entire hard drive WORKS. And the brain is nauseatingly complex, compared to a hard drive.
