Coherence induction via phase conjugate adaptive resonance coupling: Computer-generated sinusoidal grating patterns as a background stimulus in amblyopia treatment

Investigations in the cat’s visual cortex at the Franfurt Max-Plack Institute of Brain Research have shown phase decoherence of the cortical processing to be a main parameter determining the low vision problem in strabismic and refractory amblyopia. In order to cope with the low vision problem we developed a training software incorporating a certain kind of background stimulation for the amblyopic eye. In front of the stimulus a computer game maintains the patients attention. The stimulus itself is a continuously drifting sinusoidal grating selectively tuned to a certain range of spatial and temporal frequencies. The main idea behind the stimulation is to regain the coherence of visuo-cortical processing inducing phase conjugate adaptive resonance in chanels of visual filter systems. This is aimed by stimulus-induced phase coupling between reciprocally tuned sensory channels of high spatial and low temporal frequency (“pattern channels”) vs. low spatial and high temporal frequency (“motion channels”) which are differentially impaired in amblyopia. Details of the sketched above hypothesis and practical results of clinical and field studies are presented.
