In this video I summarize the most exciting recent developments. The first paper about inferring the meaning of nouns is: Mitchell et el "Predicting Human Brain Activity Associated with the Meanings of Nouns" Science, 1191-1195 (2008) https://science.sciencemag.org/content/320/5880/1191 The paper about extracting speech from brain readings is: Anumanchipalli, Chartier, & Chang "Speech synthesis from neural decoding of spoken sentences" Nature 568, 493–498 (2019) https://science.sciencemag.org/content/320/5880/1191 There are more examples of the reconstructed sentences here: https://www.youtube.com/watch?v=3pv0vT82Cys The paper about extracting images from brain readings is: Shen et al PLoS Comput Biol. 15(1): e1006633 (2019) https://journals.plos.org/ploscompbiol/article?id=10.1371/journal.pcbi.1006633 And the brain to text paper using handwriting is: Willett et al High-performance brain-to-text communication via handwriting Nature 593, 249–254 (2021) https://www.nature.com/articles/s41586-021-03506-2 Many thanks to Jordi Busqué for fact-checking this video http://jordibusque.com/ 0:00 Intro 0:33 How to measure brain activity 2:44 Brain to Word 5:42 Brain to Image 6:30 Brain to Speech 7:25 Brain to Text 8:29 Better ways to measure brain activity 10:20 Sponsor Message
