I’m assuming you are asking if the brain uses transformer-like structures or otherwise exhibits similar behavior. I don’t know, but it does share some processes with simpler ML ideas, and I’d be very interested to see if it uses anything resembling a transformer.
Forward-forward algorithm is more like the brain. As I understand, backpropagation transformers require storing data, doing calculations on that aggregate, and sending it back through, which no neural structures can do anything like.
