Die Forscher entwickelten eine schmerzlose Behandlung mit Funkwellen, um den Einzelpersonen zu helfen, ihren Geruchssinn wiederzugewinnen, zu bewahren oder zu verbessern

>In the study, the team asked volunteers with a healthy sense of smell to sit while a small radio antenna was placed near, but not touching, their forehead. For five minutes, this antenna gently sent out radio waves to reach the smell-related nerves deep in the brain. Before and after the short treatment, the authors tested how well the patient could smell very faint odors, like diluted alcohol or fruit scents, using pen-shaped odor dispensers called Sniffin’ Sticks. They also recorded the patients’ brain signals to see how active their smell nerves were.

>The team found that their method improved subjects’ sense of smell for over a week after just one treatment.

>“This study represents the first time that a person’s sense of smell has been improved using radio waves without any physical contact or chemicals, and the first attempt to explore radio frequency stimulation as a potential therapy for neurological conditions,” Jang said.

>The results of the current study, which focused on people with a normal sense of smell, could help professionals such as perfumers, chefs, or coffee tasters, who need to distinguish aromatic subtleties. The method could be also used to preserve or even enhance the sense of smell.

Curious if this could be used for those people who lost their sense of smell permanently (or had it diminished long-term) from Covid.
