Nobody does, but it is being worked on.

Functional magnetic resonance imaging does give some insight into where 
the processing happens as various - short - times after the human brain 
has been exposed to a stimulus. Not a hell of lot so far, but it is 
being worked on.

They seem to work in speech recognition

https://theaisummer.com/speech-recognition/

I knew a couple of people that worked on that, and lots of neural nets 
didn't work, but there seems to have been progress on finding variations 
that can be made to work progressively better.
