Happy to share our new paper rdcu.be/e0fLA in Nature Communications with @FindlingCharles, Margaux Romand and @vasilisa_skv: How neural variability/noise in the prefrontal cortex contributes to efficient adaptive behavior without facing computational complexity issues!

@StanDehaene Cher Stan, je t'adresse toutes mes condoléances et te remercie pour ce bel hommage à ton père, médecin et scientifique si inspirant.

Mon père, le docteur Philippe Dehaene, est mort vendredi dernier 9 décembre 2022, à 94 ans. Je voudrais rendre ici hommage à ce très grand pédiatre, chercheur spécialiste du syndrome d'alcoolisation foetale (SAF). (1/n)

Happy to share our new paper rdcu.be/ctZBi with the great contribution from @ali_r_soltani

here is our paper doi:doi.org/10.1038/s41562…

Glad to share our new paper rdcu.be/b9935 in @NatureHumBehav entitled "Imprecise neural computations as a source of adaptive behaviour in volatile environments" by @FindlingCharles, Nicolas Chopin and @KoechlinE. The Weber Law in inferring stable state beliefs is key!

Our new paper science.sciencemag.org/content/369/65… by @PhilippeDOMENE2, Sylvain Rheims and @KoechlinE describing with model-based intracranial EEG how the prefrontal cortex resolves exploitation-exploration dilemmas through predictive coding between the vmPFC and dmPFC. @ScienceMagazine

Thrilled to share the final version of our work @eLife! doi.org/10.7554/eLife.… @StePalminteri @KoechlinE @ostojic_srdjan

Our last paper describing how to go beyond the rational decision theory through the notion of adaptive behavior

Showing how noisy computations conforming to the Psychophysical Weber Law dispense humans to make complex inferences about environment volatility to exhibit efficient behavior in volatile environnements!!!

Our last paper biorxiv.org/cgi/content/sh… just released entitled “imprecise neural computations as source of human adaptive behavior in volatile environments” by @FindlingCharles, Nicolas Chopin & @KoechlinE.

New @biorxivpreprint on agency, instrumental learning and counterfactual simulation: "Believing in one's power: a counterfactual heuristic for goal-directed control", with Héloise Théro, @FindlingCharles and @KoechlinE #preprint #christmasreading 1/8 biorxiv.org/content/early/…

Complement our last study doi.org/10.1093/cercor… in Cerebral Cortex by Sandrine Duverne et Etienne Koechlin about ACC-DLPFC interaction combining rewards and cognitive control. All open access!

We show that subjective probabilities reflect that proper beliefs encoded in the vmPFC are treated as affective signals that add up to rewards values in the ACC rather than as probabilities underlying expected value computations

our new paper doi.org/10.1038/s41467… in Nature Comm "prefrontal mechanisms integrating rewards and beliefs in human decision-making" by Marion Rouault, Jan drugowitch @jdrugowitsch and Etienne Koechlin @KoechlinE. It is about the neural sources of subjective probabilities
