SUMMARY:Neural dynamics of feedforward and feedback speech processing
DESCRIPTION:Adeen Flinker\, PhD\, New York University\, Grossman School of Medicine\, Tandon School of Engineering \nSpeech production is a complex human function requiring continuous feedforward commands together with reafferent feedback processing. The cortical organization of these processes are largely characterized by dual stream models of speech (Hickok & Poeppel 2007\, Rauschecker & Scott 2009)\, wherein Frontal cortex mainly serves as an articulatory network mapping feedforward commands. Leveraging human intracranial recordings\, I will present a series of studies addressing the role of prefrontal cortex in processing feedforward and feedback speech commands in support of a mixed representation across frontal cortex. I will argue for a functional subdivision of precentral gyrus wherein the ventral division sends feedforward commands and serves as the source of a corollary discharge\, while the dorsal division carries out auditory feedback processing of reafferent speech.
