On ne peut pas parler de personnalités « cerveau droit » ou « cerveau gauche »

J’ai déjà abordé ici cette idée (malheureusement) fort répandue que certaines personnes seraient plus « cerveau droit » et d’autres « cerveau gauche », les premières étant soi-disant plus créatives et les secondes plus rationnelles. À partir de l’article « An Evaluation of the Left-Brain vs. Right-Brain Hypothesis with Resting State Functional Connectivity Magnetic Resonance Imaging » publié en 2013 dans la revue Plos One, on avait pu constater que ces affirmations n’étaient pas corroborées par cette…

Adapting the language of computers for regenerative medicine

In many regenerative medicine strategies, we know that one strategy is usually not enough. Stimulating regeneration in any tissue is a complex, multifaceted problem involving the coordination of many biological signals. Yet what if we could deliver a therapeutic, like a drug or cells, to the body in such a precisely controlled manner that we knew exactly when it would be released, and for how long? Or if we could deliver multiple therapeutics at once,…

Do Some Cats Respond Quietly to Catnip?

Young kittens don't have an active response to catnip. But if you think your cat does not respond to catnip, maybe it's just a quiet response, according to a recent study.Photo: Prasom Boonpong / ShutterstockIt is widely believed some cats respond to catnip and some cats don’t.

Gradients corticaux (bis), hypnose et intelligence artificielle

Comme je vous l’avais promis la semaine dernière, avant de vous parler de deux cours de l’UPop Montréal qui risquent fort d’intéresser les lecteurs et lectrices de ce blogue, je reviens brièvement sur cet article qui vient tout juste de paraître (janvier 2018) dans Trends in Cognitive Sciences (TICS) et qui s’intitule «Large-Scale Gradients in Human Cortical Organization». On avait déjà décrit dans le dernier billet comment ce gradient des régions les plus unimodales du…

  Can you find love in your genetic code? Is there such a thing as DNA-crossed lovers? Some direct-to-consumer companies, like "Instant Chemistry", want to test the compatibility of your relationship by looking at your genes... but is there clear science on this issue or is this repackaged astrology? My latest video for the McGill Office for Science and Society!

What is the most effective form of birth control, and how come there's no pill... for men? One thing's for certain: McGill students are going to have a lot of unplanned babies if the vox pop is any indication!

Are crows just as good at planning as the great apes?

Over the years, many studies have been published on the intelligence of crows, ravens, jays and other corvids (members of the crow family). But according to several specialists on the subject, a study entitled “Ravens parallel great apes in flexible planning for tool-use and bartering,” published in July 2017 in the journal Science, reveals that birds in this family have a heretofore unexpected ability to plan a future behaviour after learning something under experimental conditions.…
