In general the patterns are the same and the brain areas involved are the same but there is definitely individual variability, too. There is probably much less individual variability in visual cortex than, say, language representation areas (consider English speakers vs Spanish speakers) but there is likely enough that they have to retrain their algorithms for each individual to achieve optimum discrimination.
- Asmodeus 17y agoThere is indeed enough variation. I unfortunately can't find the link, but they went further and had people imagine something like the letter 'n,' and of the whopping eight people they tested, one came out completely garbled, even after training. Also, I suspect that variation increases with abstractness, so it will almost certainly be impossible to extract high level thought without extensive cooperation. For example, the brain state that the word 'conciousness' invokes in me is going to be entirely different from you because I have different associations, examples, knowledge, and general representation. Now try to extract an entire sentence without training first. Have fun!
