Abstract : Microelectrode investigations in the central visual pathways under Nembutal anesthesia demonstrated that the type of tonic response to illumination depends on the level of the impulse firing rate during dark adaptation. Micro-and macroelectrode researches in the pretrigeminal preparations seem to substantiate these results and prompted an investigation of the possibility of modifying the level of discharge of the retina in darkness in a light-independent way. The results were positive. Microelectrode investigations on the pretectal region were performed with the purpose of describing the processing of visual information which is at the base of the sensory-motor integration in the pupil-motor structures.
