New articles
Our two first sEEG studies conducted in Grenoble are now both out in Nature Communications! The first, led by François Stockart, describes how evidence accumulation taking place in the mid-fusiform cortex serves perceptual consciousness. The second, led by Dorian Goueytes, describes how post-decisional evidence accumulation in the insula is used to form confident judgements and enables changes of mind. And there’s more to come!

New preprints & Nathan @Chapman

We have submitted two preprints summarising our sEEG work over the last 5 years. The first, led by François Stockart, describes how evidence accumulation in the mid-fusiform cortex serves perceptual consciousness. The second, led by Dorian Goueytes, describes how post-decisional evidence accumulation in the insula underlies confidence and changes of mind.

Meanwhile, Nathan is a visiting professor at Chapman University (CA, USA) for three months, developing new research lines with Uri Maoz and Aaron Schurger on the scientific study of consciousness.

ERC Consolidator Grant
Thrilled to announce that we obtained an ERC Consolidator Grant! The project called Volta seeks to determine how evidence accumulation defines the stream of consciousness using LFP, SUA, and voltammetry recordings — in awake, sleeping, and anaesthetized humans. We will be hiring 3 PhD students and 3 postdocs starting in 2025. Reach out if you have expertise in electrochemistry, signal processing, and consciousness research!

New lab members
We are happy to welcome two new lab members! Perrine Porte starts as a PhD student working on multisensory consciousness and metacognition. Jeanne Caron-Guyon joins as a postdoc working on the neural correlates of consciousness during sleep. Welcome!
September 2023
New preprint
We submitted a new sEEG study led by Dorian Goueytes, showing that both confidence and changes of mind derive from post-decisional evidence accumulation, notably instantiated in the insular and orbitofrontal cortices. Details here.
April 2023
New preprint
We submitted a new study led by Marie Chancel using a new continuous reproduction task to measure global confidence estimates. We show that participants monitor both endogenous and exogenous sources of uncertainty to estimate confidence. Details here.
March 2023
New preprint
We submitted a new study led by Martin Rouy documenting preserved metamemory and metaperception in schizophrenia. Details here.
February 2023
New articles & new grants

Our study documenting preserved electrophysiological markers of confidence in schizophrenia is now published in Schizophrenia. Congrats to Martin Rouy and team! Details here.

We are also thrilled to announce that Michael Pereira was awarded an ERC Starting Grant, and Dorian Goueytes was awarded a Marie Skłodowska-Curie Postdoctoral Fellowship. Congratulations!

October 2022
New preprint
We published a follow up to our previous behavioural study showing no impairment of metaperception in schizophrenia. Here, we analysed EEG data collected during the task and found that electrophysiological markers of confidence were similar between individuals with schizophrenia and healthy controls. Details here.
September 2022
New article
Our opinion article regarding the ethics of animal consciousness research is now published in Perspectives on Psychological Science! Details here.
April 2022
New article
Together with Michael Pereira and Denis Perrin, we propose a Leaky Evidence Accumulation Process (LEAP) to explain dynamic properties of perceptual consciousness and associated confidence ratings. Details here.
January 2022
New article & new members

In a replication study led by Martin Rouy, we found that a previous attempt to improve metacognitive performance through feedback is likely impacted by experimental confounds. We address these confounds and discuss alternative ways to improve metacognition. Details here.

We also warmly welcome new lab members: Childéric Dezier, Perrine Porte, and Clément Sauvage join for 5-month internships as part of their Masters at Université Grenoble Alpes. And we are very happy to welcome Marie Chancel as a new postdoctoral scholar in the metAction team!

New lab members & new article

We are delighted to welcome Ramla Msheik and François Stockart as new PhD students, and Dorian Goueytes as postdoctoral scholar. Welcome on board!

We also published a new fMRI study led by Giedre Stripeikyte in collaboration with Olaf Blanke’s lab, showing that the attenuation phenomenon extends beyond sensory events to non-perceptual cognitive processes. Details here.
March 2021
Habilitation & new articles

Nathan obtained his accreditation to supervise research (HDR). His defense gives an overview of past, present, and future research.

Our meta-analysis of metacognitive deficits in schizophrenia was accepted in Neuroscience & Biobehavioral Reviews. Congrats to all authors, and specially to Martin Rouy for his first publication! Details here.

Our preprint linking evidence accumulation with perceptual consciousness and monitoring was accepted in Nature Communications. Congrats to Michael Pereira and co-authors! Details here.

New members & talks

We are lucky to host 6 new students: warm welcome to Eugénie, Lise, Flore, Hanna, Hugo, Ramla, and Wassila!

Audrey Kist obtained a PhD scholarship from the French government to investigate the subcortical correlates of consciousness in collaboration with Mircea Polosan.

Michael and Martin also presented their work at Neuromatch 3.0.
September 2020
New article
Our study showing similar meta-performance between individuals with schizophrenia and matched controls is now published in the Journal of Psychiatry and Neuroscience. The manuscript, code, and data are available here.
July 2020
New preprint
In a new study led by Michael Pereira in collaboration with HUG and the Wyss Center, we recorded single neurons in a human participant while he provided detection and confidence judgments. Combining this with EEG recordings and a computational model, we show that evidence accumulation by parietal neurons is a shared mechanism between conscious detection and confidence. This preprint later became our Nature Communications paper.
March 2020
New article in PNAS
Our EEG-fMRI study investigating the origins of confidence was accepted for publication in PNAS! The manuscript, code, and data are available here.

New team member
We are absolutely thrilled to announce that Michael Pereira joins the team as an SNF mobility fellow! Michael has been collaborating with us for the last two years and will investigate the subcortical correlates of consciousness using Deep Brain Stimulation, in collaboration with the University Hospital in Grenoble and West Virginia University.
August 2019
New members & new preprint

Martin Rouy joins the team as the first of two PhD students funded by the metAction ERC grant. His work will consist in developing new tasks to capture metacognitive deficits in schizophrenia using psychophysics and EEG. Welcome on board!

Together with Elisa Filevich and Christina Koß, we also submitted a new study assessing the influence of action execution on confidence and metacognition. Against our pre-registered hypotheses, results show that decision execution does not influence metacognitive performance. Details here.
April 2019
New articles & new team member

Together with Jean-Paul Noel and colleagues, we quantified the role of consciousness for multisensory integration. Our results show that the broadcasting of sensory information portends a graded relation between perceptual awareness and multisensory integration. Data and scripts are available at OSF.

We are also happy to announce that Lucien Gyger will be the first full member to join the team in October! He will kickstart the experiments described in the metAction project.
February 2019
ERC Starting Grant!
The project metAction was awarded an ERC Starting Grant of 1.4M€ for five years! We are looking for PhD students and postdocs starting early 2019.

December 2018
New preprint
After two years of work, our study investigating the origins of confidence is now online: with Michael Pereira and Iñaki Iturrate, we combined EEG, fMRI, and computational modeling to disentangle decisional and post-decisional contributions to confidence. This work later became our PNAS paper.
