2018 AANS Annual Scientific Meeting-613. The Roles of Rhythm and Prediction in Speech Perception

613. The Roles of Rhythm and Prediction in Speech Perception

Video Transcription

Video Summary

In this video, Dr. Nitin Tandon discusses the roles of rhythm and prediction in speech perception. He explains that language relies on the brain's ability to anticipate and match expectations of what will be said. This concept is referred to as entrainment, which involves synchronization between external stimuli and the brain's response. Dr. Tandon conducted a study with 31 patients who participated in a rhythmic white noise task. Using electrodes implanted in their brains, he observed how the brain quickly entrained to the rhythm and continued to do so even after the stimulus ended. The study found that specific areas in the superior temporal gyrus were involved in this entrainment and played a role in speech perception. Dr. Daniel Yosher provides commentary on the research, emphasizing the importance of understanding auditory cortex and language processing.
