研究目的:

本研究试图通过靶向小脑的神经调控 (1)检验其对精神分裂症患者序列预测功能的改善效果,并是否能够改善社会快感缺失。 (2)探讨其改善是否与序列预测相关的小脑及小脑-大脑的功能激活与连接的改变有关。  

Objectives of Study:

This study investigates: (1) whether cerebellar tDCS improves sequence prediction ability in schizophrenia patients and reduces social anhedonia; (2) whether these improvements correlate with altered functional activation and connectivity in cerebellar and cerebro-cerebellar circuits underlying sequence prediction.

干预措施:

Interventions:

组别:

阳性刺激组

样本量:

40

Group:

Anodal group

Sample size:

干预措施:

以小脑Crus I和Crus II作为刺激部位,参考10-10系统332导联电极设置电极位置:中心电极(阳极)为I4,返回电极(阴极)为A31、L2、M2、M7。对于真刺激组的被试,每次接受真刺激,电流从0上升到1.5mA,维持20分钟后下降至0。

干预措施代码:

Intervention:

For anodal transcranial direct current stimulation, the stimulation electrode is placed near the I4 region at the back of the cerebellum, targeting the Crus I and Crus II regions. The four return electrodes are placed at A31, L2, M2, and M7. The subjects will receive stimulation for a total of 20 minutes, during which the current will rise from 0 to 1.5mA, be maintained for 20 minutes, and then gradually decrease back to 0.

干预措施代码:

Intervention:

For sham transcranial direct current stimulation, the stimulation electrode was placed near the I4 region of Crus I and Crus II region at the back of the cerebellum, and the four return electrodes were placed at A31, L2, M2, and M7. For participants in the sham stimulation group, each session involves sham stimulation, where the current rises from 0 to 1.5mA, then decreases back to 0, and is maintained for 20 minutes. Afterward, the current will rise again to 1.5mA and then gradually decrease back to 0.

Randomization Procedure (please state who generates the random number sequence and by what method):

All participants were numbered 1-80 according to the order of inclusion, and the subjects were randomly divided into two groups using the "randomizr" package in R language. A designated individual was responsible for determining the grouping. This person did not participate in the enrollment of cases or the implementation of the intervention and was strictly responsible for safeguarding the allocation table.

通过病例记录表收集被试的基本人口学信息,自评问卷等,通过pavlovia线上平台与psychopy线下程序进行行为任务的数据收集。数据存储中,在excel中录入数据,并保存原始的纸质材料与行为数据。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Basic demographic information of the participants, self-reported questionnaires, etc., is collected through case report forms. Behavioral task data is gathered via the Pavlovia online platform and Psychopy software. For data storage, the data is entered into Excel, and the original paper materials and behavioral data are preserved.
