Topic: visuospatial cognitive impairment

FPVS is an electroencephalography marker of discrimination between two classes of frequency tagged stimuli (standards and oddballs). The technique can detect neurodegeneration-related impairment in recognition memory without active response or task comprehension. Here, we develop FPVS as a probe of low-level visual function, with a view to its future use as a sensitive diagnostic marker of visuospatial cognitive impairment. Thirty subjects (21 (±5) years, 7 males) completed five FPVS conditions that implicitly measured their ability to discriminate an oddball line orientation (1°,5°,10°,30°,80
