Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The frequency-following response (FFR), a scalp-recorded neurophonic potential, is a widely used metric of speech encoding integrity in healthy and clinical human populations. The translational potential of the FFR as a biomarker is constrained by poor understanding of its neural generators and influencing factors. This study leverages a cross-species and cross-level approach to provide mechanistic insight into the properties of the cortical source of the FFR, and elucidate the role of cortical feedback via cortico-collicular projections on modulation of the FFR as a function of stimulus context, arousal state, and category relevance. This clinical trial will focus on the influences of category relevance, predictability, and participant arousal state on the FFRs in neurotypical human participants.
