🧑‍💻🥱 Are you feeling exhausted after endless Zoom meetings? 🤯 Our recent study, spearheaded by Ruth Feldman's lab on inter-brain synchronization during virtual conferences, might hold the key to understanding the ever-pervasive #ZoomFatigue phenomenon. 🤔 Watch my small ​CTV News​ interview to find out more! 📺 montreal.ctvnews.ca/video?clip

Freshly out: "A Novel Model for Novelty: Modeling the Emergence of Innovation from Cumulative #Culture" link.springer.com/chapter/10.1

— Kudos to Natalie Kastel for her first work with our Precision Psychiatry and Social Physiology team! — She will soon start a PhD with us, exploring Social #NeuroAI in #Multiagent Systems... 🚀

New paper: Restoring the missing person to personalized medicine and precision psychiatry

frontiersin.org/articles/10.33

> We review the limitations of precision #psychiatry arguing that it cannot reach its goal if it does not include core elements of the processes that give rise to psychopathological states, which include the agency and experience of the person.

Bernard Baars has a nice #podcast about #consciousness research and this episode on #AI is particularly interesting: youtube.com/watch?v=AUHj84ZZDl

It connects well with our recent paper « Multilevel development of cognitive abilities in an artificial neural network »: pnas.org/doi/10.1073/pnas.2201

Excited to present with JP Changeux this work during the IBM Research’s symposium « Systems Neuroscience Approach to General Intelligence (SynAGI) » next month at AAAI: researcher.watson.ibm.com/rese

@dingemansemark @andreasliesenfeld @marlourasenberg @saulalbert @abebab @cdutilhnovaes @fusaroli @davidschlangen @LizStokoe Congratulations for the piece! I can’t agree more, and even feel a bit sad to not have had the opportunity to contribute nor being cited. For >10 years I have been trying to defend this point (not always well received on top), and even made a short movie in 2011 that ends by a figure-ground reversal (see figure): m.youtube.com/watch?v=PPbH6CMw ;)

2023 offers us a new blank page, and I hope we will all find the inspiration to write beautifully on it. My new year resolution will be to act more locally, while thinking globally. Being less attracted by social media, I may disconnect and focus on writing. Just got invited to become writer for PsychologyToday.com, and I will take this occasion to actually start my first book! Let’s see how it goes… 🙂

Again, all my warmest wishes for the new year! (3/3)

I cannot say enough how grateful I am to my family, especially Marina and our little Anouk who fill my life with meaning and love, but also my friends and colleagues, especially all the members of my lab, who motivate me every day to explore knowledge and try to give back to society. (2/3)

Thanks for all your birthday messages. Wishing to all of you a wonderful new year, full of wonder and serenity to live every moment, plenty of strength and lucidity to achieve your dreams, and, of course, good health!

2022 has been full of challenges, with many losses, struggles, again a huge load of uncertainty… it reminds us how we cannot escape reality, and thus must enjoy all the bright aspects of Life and cease the good moments. (1/3)

@PessoaBrain @ShahabBakht @roydanroy

My guess is that for transformer models, they are changing their attention based on the context, and thus the "attention weights" take the continuity of the "synaptic weights", and given the depth of those architectures, it allows such sort of complex learning on the fly. Would be curious how it works for RNN. I suspect that the state of the RNN play a similar storage of constrains but this looks harder to reverse engineer.

Big kudos to Fleur Gaudfernau for her first paper, to Aline Lefebvre for her clinical coordination, to my friend and colleague @dngman for his precious help on all the @mne developments, and to the other collaborators for their contributions both scientifically and clinically!

It's the fruit of a 6-year collaboration between the Institut Pasteur and the Hopital Robert Debre in Paris,
through the SoNeTAA platform (Social Neuroscience of Therapeutic Approaches of Autism).

Note: I started SoNeTAA in a closet of the psychiatry department!

👋 Hey, #cogsci & #philosophy colleagues into #consciousness research! Does anyone get counter-arguments to the illusionist point made by Graziano in his Attention Schema Theory?

Of course, a different one than “I know I have an experience because, Dude, I’m experiencing it right now” ;)
