在轻度创伤性脑损伤（mTBI）中，连接额叶皮层和小脑的纤维束可能遭受剪切损伤，导致注意力缺陷和表现变化。当受试者同时进行眼球追踪测试和单词回忆测试时，这种损伤也会破坏认知负荷对眼球目标同步的增强。采用随机相位同步的非线性动力学技术，研究了认知负荷对正常和mTBI患者眼靶同步的影响。结果表明，认知负荷对mTBI受试者的眼靶同步产生负向影响。相比之下，在中等认知负荷下，青少年(
In mild traumatic brain injury (mTBI), the fiber tracts that connect the frontal cortex with the cerebellum may suffer shear damage, leading to attention deficits and performance variability. This damage also disrupts the enhancement of eye-target synchronization that can be affected by cognitive load when subjects are tested using a concurrent eye-tracking test and word-recall test. We investigated the effect of cognitive load on eye-target synchronization in normal and mTBI patients using the nonlinear dynamical technique of stochastic phase synchronization. Results demonstrate that eye-target synchronization was negatively affected by cognitive load in mTBI subjects. In contrast, eye-target synchronization improved under intermediate cognitive load in young (
