The device (100) has a control unit (10) and a stimulation unit (11) with a majority of stimulation elements (12,13), which produce visual stimulation signals (15,16). The stimulation elements put back a phase of a neural activity of neurons by an admission over an eye of a patient and forwarding at neurons and have a diseased synchronous and oscillator board neural activity. The control unit controls the stimulation unit such that stimulation elements produce the visual stimulation signals different from each other with different phase and with different polarity.
