Overview

This study aims to establish a novel personalized closed-loop NiBS/TMS therapeutic strategy and clinical protocol for children with Tic Disorders (TDs) through a series of scientific investigations. Additionally, it seeks to elucidate the underlying neural circuit mechanisms, enhance the therapeutic efficacy of TMS in pediatric TDs, and achieve precision neuromodulation for children with TDs.
