An electrophysiological photostimulator, particularly to study evoked visual potentials, comprises a luminescent matrix source, its surface having unit sources arranged in order under a control unit. The control photostimulator in the control unit has function, shape and form programmers, which control the stimulation source that is the luminescence matrix through an adder with a steady luminance level unit and a system for switching over the y and y lines and lighting up systems. The shape and form programmers solve the problem of dynamic stimuli understood as successive alternations of shape during one stimulus T. The described photostimulator facilitates the examinations in the field of electroencephalography, electroretinography, electronstagmography and electroocculography. Owing to the application of the other kinds of stimuli instead of the light ones the described photostimulator can successively be used in an other branches of electrophysiology, where a collective stimulation of the respective physiological organs is necessary.
