Do you remember that project that mapped where words are "stored" in the brain? I don't have it right now, but it was something like that. They used a neural approach to map the word vectors in the brain.
Here's a Guardian article about it: https://www.theguardian.com/science/2016/apr/27/brain-atlas-...
And a link to the paper: https://www.nature.com/articles/nature17637
