Spontaneous activity of single ganglion cells in the cat's retina was analyzed after different levels of illumination. It has been found that the settling time of the transient period is a characteristic of the single unit, independent of the previous illumination. It is of about 2-3 minutes. Relation between the level of illumination preceding darkness adaptation and the course of the discharge transient are presented.
