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.
