Stanislas Dehaene, neuroscientifique: «La géométrie est apparue chez l’humain bien avant la naissance de l’art figuratif» - Le Temps Si la plupart des animaux possèdent un sens approximatif des nombres, seul l’être humain est capable de reconnaître des formes géométriques simples, explique le neuroscientifique français Stanislas De...

30 ans après "La Bosse des maths", @standehaene.bsky.social replonge aux sources de ce qui fait de nous des êtres mathématiques. Dans dernier son livre "Le rectangle de Lascaux", il remonte aux sources de la #géométrie, née avant l'art figuratif.

We investigate the mental representation of geometric shapes in adults and children using fMRI and MEG. Each figure has a video of me explaining the figure: go and read it, or read below.

Excited to share our new paper in @pnas.org with @bnmorillon.bsky.social &
@valentinwyart.bsky.social www.pnas.org/doi/10.1073/...
We study three core inference systems, and how their interaction shapes human learning and decision-making.

The strongest version of this illusion I’ve seen! Absolute head-wrecker!

Lovely! But it’s missing the left hemisphere… and the visual word form area :-)

Many people have no mental imagery. What’s going on in their brains? People with aphantasia are offering a window into consciousness.

A feature in Nature examines the research about aphantasia, which is the experience of people with no mental imagery, and how it could offer a window into consciousness. #Neuroskyence 🧪

Manifolds, Dendrites, and the Geometry of Neural Computation The population doctrine—the view that populations, not individual neurons, constitute the fundamental unit of computation—has been gaining ground for years.

New Journal Club: Neural manifolds are maturing from visualization trick to biological claim. But if population activity lives on low-dimensional manifolds, what constrains the geometry?

UCL launches landmark European collaboration on perception science UCL is working with top French partners CNRS and ENS – PSL on a major European research initiative to advance understanding of human perception and consciousness.

Ever wondered how the Dalmatian Dog effect works?

The human brain can quickly learn from a single experience and generalize it to related experiences — an impressive feat so far not matched by AI.

Our new paper in @natcomms.nature.com reveals how this works.

Si les mathématiques et leurs origines vous intéressent, je vous donne rendez-vous le 28 janvier en librairie.
(Spoiler: parmi les peintures de la grotte de Lascaux figure effectivement un mystérieux rectangle...)

La recherche du code neuronal qui fait de nous une espèce unique, l’« espèce symbolique », est l’une des questions les plus passionnantes des neurosciences contemporaines. Musique, langage, mathématiques, résultent sans doute de l'émergence de propriétés nouvelles dans nos circuits neuronaux.

L'imagerie cérébrale montre que le cerveau humain abrite un circuit des mathématiques, capable de composer les nombres et les formes en une infinité d'idées nouvelles. Ce qui nous distingue des autres espèces animales, c’est la faculté de composer les idées entre elles.

Les premiers humains, avant d’esquisser des dessins réalistes, n’ont cessé de tracer des motifs géométriques : carrés, rectangles, cercles ou spirales, lignes parallèles ou perpendiculaires… D’où viennent ces archétypes ? Et pourquoi l’espèce humaine est-elle la seule à maîtriser la géométrie ?

Mon nouveau livre "Le rectangle de Lascaux : et Homo sapiens inventa la géométrie" sortira en libraire le 28 janvier.
J'y aborde l'origine des mathématiques depuis la préhistoire jusqu'à nos jours ; c'est un peu la suite de mon tout premier livre, "La Bosse des Maths". Quelques explications:
