Our review on intracranial research on consciousness is now out as a preprint: arxiv.org/abs/2510.08736. I believe that intracranial recordings provide one of the most exciting avenues for research on consciousness right now! If you agree, I think you will find the review interesting 🤓

Pre- and post-decision signals of certainty in changing minds In a recent study, Goueytes and colleagues combined computational modeling with intracranial recordings to dissect the neural basis of confidence and changes of mind. They reveal a temporally organize...

Our spotlight article on Goueytes et al. (2025) study is now online at Trends in Neurosciences: "Pre- and post-decision signals of certainty in changing minds", by P. Barttfeld, @ncomay.bsky.social, I. Embon & @guillermosolovey.bsky.social www.cell.com/trends/neuro...

New position, new social media account. After 5 fantastic years in Tuebingen, I moved to @yale.edu and the @wutsaiyale.bsky.social this summer - which means that I’ll be recruiting PhD students and postdocs. Please help me to spread the word and see current opportunities below 👇

The call for commentaries on our BBS paper is out now (deadline October 15): shorturl.at/Hu3Yu. In the paper (shorturl.at/4Rbk6), we provide recommendations and outstanding issues about designing experimental paradigms, analyzing data, and reporting the results of studies on unconscious processing 👇

1/Preprint Alert🔔: Across two experiments plus a computational model, we show the visual system compresses complex scenes into summary statistics that can guide behavior without conscious access to the task-defining features. We term this the Ensemble Blindsight effect.

Two recent #sEEG studies worth checking out if you're interested in evidence accumulation, #consciousness and #metacognition:

With @francoisstock.bsky.social, Dorian Goueytes, @meaperei.bsky.social, and many others!

Our #sEEG study is now published in Nature Communications: rdcu.be/eIkoG! 🧠
Key finding: We discovered neural evidence accumulation for visual perception that's independent of report preparation—recorded from >3000 channels across 3 experiments!

BBS just issued the call for commentaries, and we would LOVE to get yours!! The deadline is October 15th, and the reference number is BBS-D-24-00489R2. Looking forward to hearing what you think about our suggestions for how to study unconscious processes!

Our paper about contention and consensus in unconscious processing research is now out in Behavioral and Brain Sciences. Check out Maor's thread! Please consider sending a comment, we are interested to continue this discussion 🤓

Topia - Real-Time Interactive Spatial Communication Engine Build, deploy, and customize real-time social experiences inside accessible virtual worlds. Bring people together to work, learn, and collaborate. Free to start

The event is hosted on Topia (topia.io) and free of charge (thanks to generous support from ASSC). But note that the number of participants is limited, so don’t wait to register. See you on July 3!

The event will take around 2.5 hours. In the first phase, participants will be assigned to private rooms in pairs and have 5 minutes to introduce themselves before rotating. In a second phase, all participants will gather in a public space structured to enable small-group discussions 🤓

ASSC Ice-Breaking Event Made with Tally, the simplest way to create forms.

Are you an early-career ASSC member who wants to meet peers interested in consciousness ahead of the @assc28.bsky.social conference? The @ASSC Community Building Committee has the right event for you! Join us for an online ice-breaking event on July 3. Sign up here before June 25: tally.so/r/3qMyQk

Subcortical correlates of consciousness with human single neuron recordings Subcortical brain structures contain neurons encoding subjective reports of stimulus detection in human participants, suggesting a role for conscious perception.

New “version of record” in @elife.bsky.social! ‬

We recorded neurons in the thalamus and subthalamic nucleus of humans and found both sensory- and perception-selective neurons with two distinct latencies!

Hi Bluesky!

I want to let you know about a cool new paper I had the honor of being a part of:

Semantic priming modulates the strength and direction of the Kanizsa illusion

Leaky evidence accumulation accounts for perceptual confidence and subjective duration Perceptual consciousness is defined as the subjective experience associated with the processing of sensory cues from the environment. Subjective experience unfolds over time and is accompanied by a se...

Through thick and thin, the ultra-resilient Ramla Msheik completed the main study of her PhD, which supports leaky evidence accumulation as a computational mechanism underlying perceptual confidence and subjective duration. Check it out!

Excited to see this out 🥳 Come check out the website and explore studies of unconscious processing!

Our UnconTrust database for studies of unconscious processing is now officially launched in an interactive website here: uncontrustdb.tau.ac.il
And a paper describing the process and validation is now published in “Scientific Data”: doi.org/10.1038/s415...

... and this is our new contribution to #metacognition research, this time showing a functional overlap between evidence accumulation, confidence, and changes of mind using sEEG:

Brilliantly led by Dorian Goueytes, + @meaperei.bsky.social and many others!

Thanks!

I want to thank my supervisors (@nfaivre.bsky.social and @meaperei.bsky.social) for their constant help and support, as well all co-authors (including @liadmudrik.bsky.social ) and all the people in Grenoble and Brno without which this project would never have been possible!

We conclude that our results provide support for the claim that evidence accumulation processes occur beyond decision-making and can explain at least different facets of perceptual experience. This view entails that conscious access can occur at varying latencies.

Finally, Ramla Msheik ran model simulations based on a leaky evidence accumulation process and reproduced the results observed in the ventral visual cortex, indicating that this regions might be implementing leaky evidence accumulation for perceptual experience!

Decoders in the ventral visual cortex also reflected non-veridical percepts, when participants reported seeing a face when none was presented or reported seeing more than one face when only one was presented.

To assess if the same neural code underlies all these responses, we tested if a multivariate decoder trained on immediate detection could reflect evidence accumulation, delayed detection and confidence, and passive perception. We found such signatures in the ventral visual cortex.

Additionally, we asked participants to report confidence in their detection in the delayed-response experiment. In several regions including the ventral visual cortex, the HGA was modulated by perceptual confidence independent of stimulus intensity.

The results at the region level seemed to be mostly driven by channels located in the mid-fusiform gyrus, consistent with the location of the fusiform face area.

Looking at pre-registered regions of interest, the ventral visual cortex was the only region that was found to (1) accumulate evidence, (2) reflect detection and (3) respond to stimulus intensity during passive perception.

Populations of neurons involved in conscious access should respond more strongly to suprathreshold than threshold stimuli, as the former were perceived consciously more often. The HGA of some channels displayed this effect, mirroring the effect of detection in experiment 2.
