Investigating How the RECT Impacts Brain Functional States Through the ACC-cerebellar Loop

Rövid összefoglaló (regiszter, angolul)

Experiment1: Using a brain EEG-TMS combined system, researchers aim to investigate the impact of the rostral anterior cingulate cortexr (rACC)-engaging cognitive task (RECT) combined single-pulse TMS magnetic stimulation on theta neural oscillations in the medial frontal lobe. The study will be divided into 4 groups: the first group will receive left cerebellar single-pulse TMS stimulation combined with the RECT task, the second group will receive right cerebellar single-pulse TMS stimulation combined with the RECT task, the third group will receive midline cerebellar single-pulse TMS stimulation combined with the RECT task, and the fourth group will receive sham cerebellar single-pulse TMS stimulation combined with the RECT task. Divide the participants into groups of 15 people each, following a 1:1:1:1 ratio. Based on the above testing, the stimulus method that results in the most significant change in the midline of the frontal lobe will be identified. Experiment 2: Based on the research from Experiment 1, the most significant approach affecting theta neural oscillations in the medial frontal gyrus will be identified. This stimulation protocol will be combined with left dorsolateral prefrontal cortex iTBS stimulation in Experiment 2. The research aim of Experiment 2 is to investigate the most effective stimulation method for enhancing midline theta neural oscillations in the frontal lobe, in combination with left dorsolateral prefrontal cortex iTBS, for the treatment of post-stroke depression patients. This study will include 40 post-stroke depressed patients, and each participant must meet the inclusion criteria. The first group of participants, consisting of 20 individuals, will receive the optimal combination intervention. The second group of participants will only receive iTBS stimulation, without any additional intervention strategies used in Experiment 1. Patients will undergo Hamilton Depression Scale assessment and resting state and task state EEG collection at baseline, one week after intervention, and two weeks after intervention.The primary outcome will be the Hamilton Depression Scale, with EEG-related data being analyzed as a secondary outcome. Task-oriented EEG detection will include both facial expression recognition paradigm and oddball experiment paradigm. Reaction time, accuracy, and completion status will be recorded simultaneously in the experiment. The experiment will record patients' tolerance and any adverse events that occur.
