The CRNL mobilizes against Covid-19 outbreak with new research

The CRNL teams have mobilized against Covid-19 around 4 major research themes: olfaction, sleep, mental health and pain. New studies have emerged to understand the neurobiological mechanisms of the virus but also the consequences of containment.

Some odorants act as rewards on our brain


An article of Maëllie Midroit* and Laura Chalençon* under the direction of Nathalie Mandairon, NEUROPOP CRNL, in Current Biology.

Why are we so attracted to some odorants? A study published in the journal Current Biology shows that pleasant odorants can act as rewards on our brains. This specific property of odorants seems to be due to a special connection between two brain regions, the olfactory bulb, which deals with odor pleasantness, and the olfactory tubercle, a key structure of the reward system. The activation of this network allows dopamine release, as do natural beneficial stimuli such as food or artificial stimuli such as drugs. These results obtained in mice have been confirmed in humans, showing that this process is conserved between species.

Efficacy in deceptive vocal exaggeration of human body size


Body size exaggeration is common in the animal kingdom, with many species having evolved adaptations to look or sound BIG in order to threaten competitors or attract mates. But to what extent does such deception actually fool listeners?
To answer this age-old question, researchers Kasia Pisanski and David Reby (ENES CRNL) examined the perception of deceptive vocal signals of body size in humans. “By studying deception in our own species”, explains Prof. Reby, “we can answer many important questions about deceptive signalling that are difficult to tackle in studies with non-human animals”.

En finir avec les neuromythes


"We only use 10% of our brain's capacities", "To each his own learning style", "Everything is decided before the age of 3"... We think we know a lot about how our brain works. What if these preconceived ideas don't make sense?

With Covid-19, we finally put the nose on the loss of the sense of smell


The olfactory deficit, one of the effects of Covid-19, generates real difficulties in social life, which can result in a tendency to isolation or depressive symptoms. In this post published with Libération, three specialists (Moustafa Bensafi, Catherine Rouby, Camille Ferdenzi, NEUROPOP CRNL) give their analysis and call for better medical care.

Podcast CNRS « How does Covid-19 disturb our sense of smell? »


While a large proportion of people suffering from Covid-19 have problems with their sense of smell, neuroscientist Camille Ferdenzi (NEUROPOP CRNL) explains in this podcast the various ways in which the virus can alter this sense, but also how it can be regained through olfactory rehabilitation.

A new artistic residency at the CRNL!


Within the framework of « Nez à Nez » project (Nathalie Buonviso, Alexandra Veyrac, CMO CRNL), an artistic residency took place on January 21 and 22, 2021, supported by our tutors (CNRS, Inserm, UCBL, UJM).

Why do some people remember their dreams better than others?


An article in CortexMag about the work of Raphaël VALLAT, Alain NICOLAS and Perrine RUBY (PAM CRNL). "Postulating that the moment of awakening was crucial to memorize dreams, these researchers proposed to big and small dreamers to take a nap in a scanner and observed what was happening in their brain when they woke them up."

Why is music good for us?
