<jats:p>Olfaction is one of the most ancient senses, as evidenced by the presence of a highly developed region in the brain of lower vertebrates. Olfaction plays an important role in human life, influencing behavioral and emotional reactions, including the formation of the maternal instinct. The olfactory epithelium consists of olfactory receptor and basal cells located among the cells of the mucous membrane in the upper part of the nasal cavity, the number of which is significantly smaller than in representatives of the animal world. The axons of receptor cells form the olfactory nerve, the branches of which extend along three pathways through subcortical structures to the cortical region. Earlier theories of olfaction are of historical interest. At present, receptor proteins, responsible for interaction with odorants, play a key role in the olfactory.mechanism.</jats:p>
