研究目的: |
构建认知任务负荷分级体系:基于自然主义电影材料,开发具备可控负荷梯度的任务片段库,并建立融合认知心理学理论与神经生理指标的多维量化标注体系。 探索任务负荷与神经激活的关联机制:采用功能神经成像等手段,系统分析不同认知负荷等级下的脑区激活模式与动态功能网络特征。 |

|
Objectives of Study: |
Objective 1: To construct a cognitive task load grading system by developing a library of naturalistic movie clips with controllable load gradients and establishing a multidimensional quantitative annotation framework that integrates cognitive psychology theory and neurophysiological indicators. Objective 2: To investigate the relationship between task load and neural activation by systematically analyzing patterns of brain region activation and dynamic functional network characteristics across different cognitive load levels using functional neuroimaging . |

药物成份或治疗方案详述: |
检测方案:近红外脑功能成像检测脑血流分布。检测设备:使用多通道连续波近红外成像设备(BS-3000,武汉资联虹康)采集受试者的脑血流数据。该设备共有32个半导体激光光源与32个雪崩光电二极管探测器组成。其中,光源入射波长λ1|2=690|830nm,最大功率>=30mW;探测器样频率可调节,范围20Hz~100Hz。设备的光源和探测器基于10-20国际标准导联系统的头帽分布于双侧前额叶、额顶感觉运动皮层、颞叶与枕叶,共组成106个通道。 治疗方案:仅研究三涉及,选取经颅磁刺激,具体靶点及强度由研究一二结果决定。 合并用药:研究一:健康人中不允许使用可能影响中枢神经系统功能的药物(如镇静剂、抗抑郁药等)。研究二三:不影响合并用药,但需要记录用药情况。 |

Description for medicine or protocol of treatment in detail: |
Detection Protocol: Functional near-infrared spectroscopy (fNIRS) was employed to assess cerebral blood flow distribution. Detection Equipment: A multi-channel continuous-wave near-infrared imaging system (BS-3000, Wuhan Zilian Hongkang) was used to acquire cerebral hemodynamic data from participants. The system comprises 32 semiconductor laser sources and 32 avalanche photodiode detectors. The laser emission wavelengths are λ1|2= 690|830 nm, with maximum output power >= 30 mW. The detector sampling frequency is adjustable within the range of 20 Hz to 100 Hz. Sources and detectors are positioned on a cap according to the international 10–20 EEG electrode placement system, covering bilateral prefrontal cortex, frontoparietal sensorimotor cortex, temporal lobes, and occipital lobes, forming a total of 106 measurement channels. Treatment Protocol: Only Study III involves intervention, utilizing transcranial magnetic stimulation (TMS). The specific stimulation target and intensity will be determined based on the findings from Studies I and II. Concomitant Medication: Study I: Healthy participants are not permitted to use medications that may affect central nervous system function (e.g., sedatives, antidepressants). Studies II and III: Concomitant medication is allowed, but detailed medication records must be maintained. |

Randomization Procedure (please state who generates the random number sequence and by what method): |
Study 1 and 2: No randomization method is involved. Study 3: Eligible subjects will be randomly assigned in a 1:1 ratio to either the conventional stimulation group or the targeted stimulation group (with the target determined by the results of Studies 1 and 2) using a random number table method. |

Blinding: |
None (Studies 1 and 2) Study 3: Phase 1: Triple-blind (Participants, outcome assessors, and intervention executors are all blinded to group assignment) Phase 2: Single-blind (Outcome assessors are blinded to group assignment) Additional Notes: Intervention executors will utilize a centralized randomization system or pre-packaged parameter protocols (displaying only protocol ID numbers, without revealing specific group assignment or parameter details) to administer the stimulation, thereby ensuring they remain blinded to the participants' specific group assignment . |
