Abstract: A visual stimulation method and system for the field of electrophysiology of vision to obtain the suppression of the recording artifacts due to the luminance transients of the LCD monitors during the inversion of a main stimulation pattern (17) composed of a plurality of geometric elements, each of which is represented by a pair of complementary micropatterns (21, 22) and where the micropattern of each pair alternate between them in a synchronised manner with the frame rate.
Abstract: A method and apparatus for visual stimulation and recording of the pattern electroretinogram (PERG) and of the visual evoked potentials (VEP), by way of transient and steady-state visual stimuli, including a simultaneous transient and steady-state stimulation of a plurality of zones of the visual field visualization element, and an algorithm able to reconstruct the second harmonic component of the steady-state signal and the transient signal of the zones.
