Activation of Human Extrageniculostriate Pathways after Damage to Area V1

  title={Activation of Human Extrageniculostriate Pathways after Damage to Area V1},
  author={Maurice Ptito and Peter Johannsen and Jocelyn Faubert and Albert Gjedde},
We have used positron emission tomography (PET) to specify the cortical and subcortical structures activated following visual stimulation of the scotomatous field in a patient with an asymmetric bilateral developmental anomaly of the visual cortex. Computerized perimetry indicated a left visual field defect only although MRI and 18FDG-PET scans showed abnormalities in both occipital lobes. The visual stimuli were semicircular gratings moving in opposite directions on a dynamic random-dot… CONTINUE READING
