A polygraphic study on extinction of the somatic (EMG), autonomic (finger plethysmogram, galvanic skin reaction, respiration, pulse) and EEG (acoustic-evoked potential and EEG-blocking reaction) components of the orienting response elicited by a repetitive auditory stimulus during successive (weekly) sessions was performed in 33 enuretics and in 72 matched subjects in two control groups. The study evidenced significant retention disturbances of orienting response extinction (i.e. of learning), the "saving" of stimulations achieved from one session to the other to obtain the extinction criterion being lesser in enuretics than in normal subjects of control group I. However, the "saving" of stimulations was significantly bigger than that in patients with symptomatic epilepsy of control group II. The severity of these extinction retention disturbances in enuretics depended on the subject's age, the history of nocturnal involuntary micturitions and their clinical form, as well as on the etiology of episodes.
