摘要： 目的探讨大脑视觉认知抗干扰能力的相关功能定位。方法以3类不同干扰比的视觉材料为刺激手段,以认知错误数为指标,观察8例脑顶枕结合部损伤患者的视觉认知抗干扰错误数,并与10例正常人(对照组)的结果比较。结果顶枕结合部损伤患者的视觉认知抗干扰的错误数明显高于正常人(P<0.01),且组内不同信噪比时的错误次数差异随着信噪比的减低,由无显著性意义转变为有非常显著性意义(P<0.01)。结论脑顶枕结合部可能在视觉抗干扰功能方面起重要作用。

Abstract: ObjectiveTo investigate the related functional orientation of the visual cognition antijamming ability in brain.MethodsThe number of recognizing errors of reaction to visual stimulations in 8 patients with brain lesions in conjunctions of occipital and parietal lobes was tested by three different kinds of noises from visual materials as stimulations, and error numbers as index, and result was compared with that of 10 normal persons.ResultsThe number of recognizing errors in the patients was higher than that in normal person ( P<0.01), and the signal-to-noise (SNR) lower, the number of recognizing errors was higher in the patients ( P<0.01).ConclusionThe conjunction of occipital and parietal lobes maybe play an important role in the visual cognition antijamming ability.
