OBJECTIVE: To investigate the neural correlates of verbal and nonverbal semantic processing in neurodegenerative disease. BACKGROUND: Semantic memory is often impaired in neurodegenerative disease. Neuropsychologic and functional neuroimaging studies …

Development of saccadic suppression in children

We measured saccadic suppression in adolescent children and young adults using spatially curtailed low spatial frequency stimuli. For both groups, sensitivity for color-modulated stimuli was unchanged during saccades. Sensitivity for …
