Our latest research on the neural basis of speech-motor sequencing is now published in @NatureHumBehav! Check out this high-level explainer video and read the full paper here:
nature.com
Nature Human Behaviour - Liu et al. examine the role of sustained neural activity in the planning and production of speech sequences, revealing a key role for the middle precentral gyrus.
New in @NatureHumBehav, @jessierliu, Lingyun Zhao, PhD & @ChangLabUCSF show that the middle precentral gyrus coordinates the muscle movements required to speak, challenging the longstanding view that Broca's area controls this process: https://t.co/NS0WpDVuuV

ecstatic to see this paper out! made possible through extraordinary teamwork, and special co-first duo with @matt_k_leonard. an astounding first insight into what Neuropixels can tell us about neural computation in human cortex, in support of language processing
We’re excited about our first paper looking at speech encoding in single neurons across the depth of human cortex. Out today in @nature! https://t.co/RyX8gzSwjI [1/6]
