Enhanced Visual Attentional Modulation in Patients with Inherited Peripheral Retinal Degeneration in the Absence of Cortical Degeneration

Figure 2

Representation of the task paradigm with the central (Ring₁) and the paracentral (Ring₂) flickering checkerboard rings and the interstimulus intervals. During the passive viewing condition, participants had to fixate the central red cross. During the visual memory task condition, participants pressed a button every time a repeated ring appeared (one-back task). Scale of the fixation dot has been changed to enhance visibility.
