Intermittent theta burst stimulation in adolescents and young adults with depressive disorders: protocol of a randomized, sham-controlled study with a novel sequential Bayesian design for adaptive trials

entrainment.Resting-state EEG will be recorded for five minutes before and after tACS to monitor changes in neural oscillations.Participants will complete a sentence completion task requiring to produce a direct object (e.g., The man drinks a__), with a preparation time of 800-1000 milliseconds.EEG recordings during the task performance will be conducted to detect changes in neural oscillations, and response times and accuracy will be measured after stimulation.Additionally, an oral diadochokinetic task will assess the impact of stimulation on speech motor execution.This research provides insights into intact and impaired speech motor systems, such as stuttering, and contributes to the development of neurosciencebased intervention methods in the future.
