Le lien entre la perte auditive et le déclin cognitif

Au Canada, 38% des adultes âgés de 20 à 79 ans souffrent d'une perte auditive, et beaucoup ne reçoivent jamais de traitement. De plus, les scientifiques ont découvert que la perte auditive précède souvent de 5 à 10 ans les diagnostics de démence liée à l'âge, suggérant que la difficulté à entendre pourrait contribuer au déclin cognitif - un lien intéressant qui est soutenu par des études d'imagerie montrant des changements fonctionnels et anatomiques dans le cerveau des personnes âgées.

Le sommeil et la mémoire : une histoire à retenir!

[Cet article est en anglais] It is the end of the semester again and your exams are fast approaching. Your new year’s resolution was to go from expert in procrastination to expert in time management, and yet here you are again, trying to learn three and a half months of school material in one week. Like always, you have convinced yourself that in one week, you will be able to learn, understand, and memorise all the facts and theories you need to know to pass your exams. At first, cramming doesn’t sound so bad, but as the sleepless nights turn to exhausting days, you notice it becomes harder and harder. You find yourself reading the same sentence over and over as if it’s written in a foreign language. Your flash cards and clever mnemonic devices aren’t helping as much as they did yesterday. Panic starts to set in as you realise that this is taking more time than you have left, and you wonder: “why is my memory failing me now?!”. Well, it’s likely that those sleepless nights could be taking a toll on your brain because of the interesting relationship between sleep and memory.

« Best Buddies » dans la recherche et au-delà : comment la science collaborative facilite les progrès dans la recherche en bio-imagerie de l’autisme

[Cet article est en anglais] How many times have you asked yourself whether your research has a broader impact on society? Why is it so hard to quantify the impact of our scientific endeavors? I recently sat down with a few prominent neuroscientists who are members of both QBIN and the Transforming Autism Care Consortium (TACC) network. I wanted to get a sense of the state of the art in autism bio-imaging research and what the motivating factors and benefits are behind collaborative science and inter-network initiatives in Quebec.

Soutenir les femmes dans le milieu universitaire grâce au Women’s Neuronetwork (WNN)

[Cet article est en anglais] Most academics have at some point in their lives been asked by a well-meaning friend or relative when they will get a “real job”. While the natural response is to defensively explain that completing a PhD or a postdoc is in fact a real job, the question itself is not completely out of line. While for many career paths, people enter the job market directly after an undergraduate degree or an apprenticeship, research training takes many more years – up to ten years from the start of a PhD program to landing a permanent position (with no guarantees!).

Le lien entre le stress oxydatif, le glutathion et le vieillissement

Le vieillissement est une étape normale de la vie, et tout comme le reste du corps, le cerveau change avec l'âge. Dans le cadre d'un vieillissement normal, la plupart des gens finiront par connaître des changements dans leur façon de penser, comme un ralentissement de la vitesse de traitement ou certains types de perte de mémoire, bien que les compétences et les connaissances aient tendance à rester stables ou même à s'améliorer avec le temps.

Séminaire sur les gradients d'organisation du cerveau

[Cet article est en anglais] QBIN is proud to have sponsored the 2nd edition of the Gradients of Brain Organisation workshop, which took place on the 16th of June, 2021. In total, 395 individuals from around the world registered for the event. At the peak on the zoom call, 164 individuals were online and many more watched the livestream on Vimeo.

Enlever la blouse blanche

[Cet article est en anglais] Early one January morning, I hurried out of bed and dashed to the front curb, worried that I would be late to take out my garbage and recycling in time for the collectors. Still in my pajamas with unbrushed teeth and hair, I hadn’t noticed a woman nearby rummaging through my neighbours’ recycling bags to collect bottles for consignment. She approached me to ask for any refundable bottles from my bag. Suppressing my discomfort at the idea of a stranger examining my waste, I opened my bag to allow her to investigate. She sparked a conversation about her distrust of the COVID-19 vaccine and warned me to avoid it at all costs. When I asked her why, she replied that the government had implanted a tracking device in the vaccine so that they could monitor us at all times. She told me that since we had never needed this vaccine before, it is suspicious for the government to insist on it now. I was so completely dumbfounded that I hardly knew how to respond.

Est-ce qu'un ordinateur peut nous faire pleurer? Question revisitée avec l'uncanny valley

Les jeux vidéo sont plus populaires et son industrie est plus rentable que jamais auparavant. Ce mode de divertissement a beaucoup changé depuis l’époque des arcades marquées par des jeux tels que Pong et Pac-Man. Les jeux vidéo modernes comportent souvent des graphiques en 3D photoréalistiques renversant en plus de présenter des scénarios complexes et engageants qui ont aidé ce divertissement à dépasser l’industrie du cinéma en termes de profits et de parts du marché. Les joueurs de jeux vidéo deviennent eux-même une partie du narratif en incarnant virtuellement des personnages à travers des jeux ayant des durée de vie dépassant fréquemment les 20 heures de jeu. C’est une expérience fort différente qu’observer une histoire de l’extérieur lors de la projection d’un film de 1 à 2 heures. Cela implique que les jeux vidéo peuvent provoquer des réponses émotionnelles bien plus fortes que les films, ce qui permet à certains jeux de devenir de véritables cultes avec des amateurs dévoués attendant avec impatience la sortie du prochain jeu d’envergure.

L'art de l'imagerie: la science rencontre la beauté

[Cet article est en anglais] While art and science are often presented as opposing forces in today’s world, the aim of the two disciplines has always been fundamentally the same: to provide a representation of the real world. This intricate link between art and science becomes more obvious as we look to past discoveries that were made before the invention of modern scientific technologies that help us capture reality, in a time when it was in many ways necessary for scientists to be artists as well.

Votre cerveau et la COVID: la pandémie change-t-elle la nature humaine?

[Cet article est en anglais] With the COVID-19 pandemic persisting for close to a year now, our daily routines and habits have changed dramatically. Those of us working from home have only a short commute from our beds to our desks, which may be convenient, but also reduces our exposure to different environments and blurs boundaries between work and leisure. Those who have lost their jobs or are shouldering childcare responsibilities on top of their work are facing numerous other challenges and changes to their lives, all of which may have lasting consequences. Most obviously, the change in routine due to public health restrictions has resulted in the visible dwindling of our social interactions. Could it be that the pandemic-related shift in our normal routines is also fundamentally changing the way we think and behave as human beings? It might be too early to tell but it’s definitely an interesting question to speculate about.
