Scientists from Sechenov University and Skolkovo University of Science and Technology have launched a clinical trial on a simulator to restore patients’ sense of smell.
Training is carried out using an electroencephalograph (EEG). An electronic diffuser sprays various scents and their combinations, and then the patient inhales them on command. EEG captures the brain’s bioelectrical impulses reflected on the computer screen. With the help of a neural interface, a program that monitors the state of the patient’s brain, the doctor monitors the relationship between the recognition of a person’s smell and brain activity.
With the help of EEG, the initial level of odor perception is stabilized, said one of the researchers, AINV Sklifosovsky, Lilia Selezneva. His colleague, Mikhail Svistushkin, says that during the treatment process, doctors monitor the changes in the brain that occur during training. Exposure to simple odors can increase the growth of olfactory receptors and “train” new neural connections to recognize new odors.
Currently, experts recruit volunteers from different age groups. According to experts, they will be able to register their training as a method of treating nasal polyps patients, people who have had COVID-19, as well as nasal cavity surgeries.
