Thirty-one people were studied as they formed speech sounds in their minds, such as “pa” and “ta.” Activity patterns in the motor cortex mirrored those used to make the mouth movements necessary to speak the same syllables out loud. In PNAS: https://ow.ly/LHIN50ZISJO

🚨& 🧵 Our new Nature paper is out! Across 46 cohorts and up to 1.14M people per Big Five trait, we do GWAS and ask how robust, generalizable and consequential the genetic signals underlying personality really are. www.nature.com/articles/s41...
