The method presented includes recording of motor responses to odor stimulation reinforced by electric games. Game olfactometry was performed in 34 young children before and after adenotomy using a specially designed olfactometer which measured an increase in the threshold concentration of odor stimulation. As an olfactory stimulus we used 50% aqueous solution of dimethoxybenzene on identification threshold values. In parallel, we recorded the following physiological parameters: galvanic-skin response, pneumography and ECG. In order to develop a stable reflex, 23 children needed from 7 to 9 reinforcements and 8 children needed from 11 to 12 reinforcements. It was found that the level of identification threshold olfactory stimulation was directly proportional to the number of reinforcements. Our findings allow us to recommend the above method for clinical application.
