OxTalks is Changing
Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
Cortical tracking of natural and artificial online speech
Linguistic units such as syllables, words, phrases, and sentences simultaneously unravel during speech processing. How does the brain parse, track, and process these concurrent linguistic units? In this talk, I will discuss our recent efforts to understand whether and how natural speech is processed online, and what role brain rhythms might play in this process. Specifically, I will discuss studies demonstrating that rhythmic cortical activity entrains to the time course of large linguist units, even in the absence of any acoustic cues for the boundaries between phrases and sentences. Similar entrainment is also observed during second language acquisition, and can rapidly appear when learning to parse an artificial language. Together, these studies show that cortical entrainment to linguistic units reliably tracks online speech processing, offering endless possibilities to objectively assess language processing in children, difficult-to-test-populations (e.g., minimally conscious patients), as well as language precursors in animal preparations to allow for cross-species comparison.
