Later VEP components (CII and CIII, greater or equal to 90 ms) are only evident when the checkerboard stimulus is perceived (presented at either 14 or 21 ms durations). The CI component may provide a useful clinical tool in the investigation of non-organic (functional) visual loss or malingering.
We are working to refine the protocol with the ultimate aim of embedding ‘checkerboard test’ stimuli in a visual stream to be used when testing children.
