Story summary

Mind captioning, published in Science Advances, generates sentences from brain activity.
It can predict what a person is seeing or picturing.
It improves on earlier keyword-only methods by using a deep-language AI model to analyze video captions.
The model creates numerical 'meaning signatures' that correlate with brain activity, enabling a decoder to produce descriptions from brain scans.
Researchers say mind captioning could help people with language difficulties, including stroke survivors.
