Ever wondered why perceptual performance fluctuates over time? We found answers and new questions in our latest project, out now PLOS Biology, by analyzing over 20 million perceptual decisions in humans and mice (plos.io/46W641Q). A🧵:


New preprint from the lab showing (another) lack of EEG expectation effects in a probabilistic cueing design 🧠⚡📈. No clear effects on ERPs or decoding performance biorxiv.org/content/10.110… Psychological Sciences Cognitive Neuroscience Hub


A few weeks ago Eelke Spaak 🦋 @EelkeSpaak.bsky.social Michael D Nunez and Romy Frömer came to Ghent to talk about Single-trial EEG analyses. This EEG newsletter tinyurl.com/4vhd32hm is all about single-trial EEG, with video's of their excellent talks ánd a bonus video with Jelmer Borst 📽️

🚨New paper🚨 "Confidence in Moral Decision-Making" now published online in Collabra: Psychology (online.ucpress.edu/collabra/artic…). A shoutout to my great lab manager @OkhanMesude and collaborators Lydia Schooler, Sara Hollander, Maureen Gill Yoonseo Zoh M.J. Crockett. A thread:

Almost three years in the making, the preprint is out! We take another stab at the question: How do humans learn from reinforcement? (Spoiler alert: the answer is _not_ Reinforcement Learning). Huge thanks to the dream team: summerfieldlab @summerfieldlab.bsky.social Nathaniel Daw Kevin Miller


Happy to share a new preprint by the brilliant and indefatigable Miguel Vivar-Lazo. The first of several stories we want to tell with this rich dataset, which features joint measurements of choice, reaction time, and confidence along with ensemble recordings from LIP...

Delighted to share this preprint! How is the confidence in a decision represented in the brain? With Michael Shadlen we show that the lateral intraparietal (LIP) neurons that represent evidence accumulation also represent the probability that the decision is correct (i.e., confidence).



Very excited to share a new preprint where we disentangle the component processes of planning affected after damage to mPFC. With Sanjay Manohar basvanopheusden Wei Ji Ma Jan Ili Ma Patricia Lockwood John P Grogan (1/6) osf.io/preprints/psya…

Science is built on trust. What happens when someone destroys it? My first feature for The Transmitter investigates the emotional and existential fallout for one lab in the aftermath of a misconduct case. thetransmitter.org/science-and-so…

#JNeurosci: Results from Dor, Adam, John P Grogan, Sanjay Manohar, et al. demonstrate that patients with NMDA receptor-antibody encephalitis are an ideal model condition to study roles of receptors in human cognition and suggest NMDARs are critical for both maintaining

Pleased that our work from my previous postdoc with Sanjay Manohar (Sanjay Manohar) is finally published! Muscarinic antagonism reduces motivation & invigoration in humans, mediated by changes in preparatory EEG signals: doi.org/10.7554/eLife.…
