ABSTRACT
Abstract. The anatomy and physiology of the olfactory analyzer is a complex multilevel system. For objective diagnostics of the olfactory function, a reliable, proven method of registration is needed. One of such methods is the registration of evoked potentials. But for a high-quality assessment and reliable detection of the olfactory evoked potential (OEP), appropriate conditions are imposed. The potentials of the olfactory analyzer are recorded in the waking state, with masking of auditory potentials. In addition, the olfactory stimulus must have a short duration (only 200 ms), clearly calibrated for humidity, temperature, and speed, so as not to irritate the mucous membrane of the nasal cavity. In the article, we discuss the method of diagnosing olfactory evoked potentials that we have mastered.
