This week on the Nature Careers Podcast: Restoring the sense of smell to COVID-19 patients
. And in this series we speak to brain scientists all over the world about their life, their research, their collaborations, and the impact of their work.
And we also at the same time, apart from the clinical research that we do because we want to see where smell and taste disorders come from and how they develop, we also do research in the physiology of the chemical senses, that includes like gustation, trigeminal sensitivity in the nose, and olfaction.
So I guess as soon as you start to work in the chemical senses, you are automatically connected to many other people in different countries because there are so few people who take care about that. So this was my interest in the sense of smell only developed later. And sort of, I think this is how life is. You know, you start something and then you have to make decisions. You go left or you go right and you take a left.
First, you have to penetrate the mucus that is on top of the mucosa. That’s why it’s called mucosa, because there is mucus. What’s happening at the level of the olfactory bulb is that there is a pattern is produced. So if we perceive, let’s say vanilla. Vanilla is not just activating one vanilla cell inside, a cell type inside the cavity.
There’s one estimate from a study from Munich where they looked at foods and how many odors are important in foods, and it’s about 250. But it’s always in there. So when you think about Cinnamon, cinnamon is this beautiful, deep smell of cinnamon, but at the same time, there is a little bit of a, slight little bit of tingling in there in the cinnamon, and this is trigeminal sensationWhen people lose their sense of smell this can have a number of different causes, like the most frequent cause is aging.
So she's the same age. And as we age together probably our sense of smell was much better 30 years ago, but does not really matter, you know? Then you have post-traumatic olfactory loss, head trauma. So thee stronger the head trauma, the more severe the head trauma, the more likely that you lose a sense of smell
And they also, first experiments and results also on visual implants, they work quite well, seem to be quite well working, at least in the auditory system.And the basic idea is that you have a sensor that is, in our case, the sensor would be in the nasal cavity. In the case of the cochlear implant, it’s close to the ear
So you need to adjust to this signal. And then after some time, you can make sense of the signal and you can understand when people greet you and say hello, Also more complex sentences. And so this could make sense.We are the very beginning. That's a project that's funded by the European Union. A couple of other parts of the team we are just one group within a team, there are people in Lyon. Moustafa Bensafi, he's the head of this is the leader of this group.
