Using functional magnetic resonance imaging (fMRI), the authors examined visual cortex function in Parkinson's disease patients who did and did not experience visual hallucinations. Patients with visual hallucinations demonstrated increased activation in the visual association cortex and deficits in the primary visual cortex, suggesting that visual hallucinations are associated with an abnormality of visual-cortex function.
作者使用功能磁共振成像(fMRI)技术,对患有和未患有视幻觉的帕金森病患者的视觉皮层功能进行了检查。出现视幻觉的患者在视觉联合皮层表现出激活增加,而在初级视觉皮层存在缺陷,这表明视幻觉与视觉皮层功能异常有关。
