Rhythmic sampling of multiple decision alternatives in the human brain - Nature Communications

How humans process competing information when making multi-alternative decisions remains unclear. Here, the authors show that the brain resolves the trade-off between “evaluating within” and “comparin...

🚨New preprint on @biorxivpreprint.bsky.social: “Competing Neural Decision Variables in Human Frontal Cortex Shape Decision Confidence” by Alessandro Toso, @ayeletarazi.bsky.social, @jrochav.bsky.social, @ktsetsos.bsky.social & Tobias H. Donner 🔗 www.biorxiv.org/content/10.1...

Competing Neural Decision Variables in Human Frontal Cortex Shape Decision Confidence

Mounting evidence indicates that decisions emerge from a competition between populations of neurons encoding the different choice options. Theoretical models propose that the outcome of this competiti...

🧠✨ Exciting new research alert! ✨🧠 Did you know that catecholamines can reduce choice history biases in perceptual decision-making? 🧐🔍 Paper: journals.plos.org/plosbiology/... With @donnerlab.bsky.social and @swammerdamuva.bsky.social

Catecholamines reduce choice history biases in perceptual decision making

How do catecholamines, such as like noradrenaline, influence the role of prior expectations in perceptual decision-making? This study shows that pharmacologically increasing catecholamine levels reduc...

Large-scale maps of altered cortical dynamics in early-stage psychosis are related to GABAergic and glutamatergic neurotransmission

Cortex-wide changes in neural dynamics in early-stage psychosis relate to GABA-A or NMDA receptors and clinical symptoms.
