My mildly grumpy opinion: this is not the first paper to show correlation between brain activity and the layers of a transformer. I know that Wang et. al (2024) have done it last year[1], but I doubt they're the only ones - I just have them in my head because I was reading their paper last week. Bonus fact: Wang et. al's paper also shows that test scores are a relevant factor in said correlation. The point that always comes to mind is: correlation does not imply causation. I guess the main contribution would be a better mapping of the areas of the brain associated with speech production, but jumping from "these two things correlate" to "these two things are essentially the same" seems to me a bit of a stretch.
