- Reposted by Guillaume Dumas🎊📜 NEW PAPER 📜🎊 Can we seriously build synthetic consciousness? And if so, where do we start? I’m super excited to present recent publication in Neuroscience & Biobehavioral Reviews where @jaanaru.bsky.social and I confront this challenge head on. 1/n
- Reposted by Guillaume Dumas1/8 Do LLMs have stable personalities? We ran 2 million tests. (Spoiler: no.) 🧵 Paper accepted at AAAI 2026 - Alignment Track Safe deployment requires behavioral consistency. We found persistent instability across scales, reasoning modes, and personas. ⤵️
- Heureux de participer à nouveau à "La Science, CQFD" sur @franceculture.fr Avec @giadapistilli.com, nous parlons d'#IA génératives devenues confidents ou substituts émotionnels, et des risques liés à la solitude et à la dépendance affective. 🎧 www.radiofrance.fr/francecultur...
- [RDV 16h !] Les IA génératives ont envahi notre quotidien au point d’endosser chez certains le rôle de confident ou de conseiller. Quelles sont les conséquences de ces assistants virtuels sur le psychisme ? 📱 Avec @giadapistilli.com et @introspection.bsky.social #ScienceCQFD
- Congrats to the team for unveiling an original solution for hands-free #VR interaction. CyberFinger is open for developer evaluation on scicortex.com — A wearable that augments hand tracking while staying practical for keyboard-driven creators. Excited to see what the community builds with it!
- This CyberMonday, we are launching the #CyberFinger to creators and developers of the #Resonite community for a developer evaluation beta now at scicortex.com. Its a hands-free wearable VR controller for optical hand tracking that plays well with keyboards. www.youtube.com/watch?v=AIAD...
- Honored to speak at Ottawa about how Canada can lead in #NeuroAI. With world-class talent, trusted institutions, & sustainable infrastructure, we can build a federated approach to AI that protects mental health & strengthens our society. Thanks @braincanada.bsky.social for the invitation!

- New study led by @quentinmoreau.bsky.social & @vchamberland.bsky.social and @ppsp-team.bsky.social 👏 We show how brain stim can shape social inference in human–machine interaction 🧠🤖⚡ New causal evidence linking rTPJ to Theory-of-Mind & Self–Other distinction, & path towards social #neuromodulation!
- 📢 Our latest work at @ppsp-team.bsky.social is now available on eNeuro! Our study explores how noninvasive brain stimulation can shape social inference during human–machine interaction 🧠⚡🤖 🔗 Read it here → www.eneuro.org/content/12/1... Thread 🧶 ⤵️
- Thrilled to see this beautiful work out! Immense kudos to @ryssamoffat.bsky.social for leading this ambitious project and to @escross.bsky.social for the inspiring collaboration. Glad to explore together how inter-brain synchrony reflects our social bonds and their evolution across generations 🧠🤝🧠
- What happens in the brain as people become less lonely? Intergenerational community programs can reduce loneliness, the underlying mechanisms remain unknown. We collected and analysed 732 🧠-scans to find out! www.biorxiv.org/content/10.1... @introspection.bsky.social + @escross.bsky.social
