How does the brain decide? 🧠

Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc.

After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up.

Transitions in dynamical regime and neural mode during perceptual decisions - Nature

Simultaneous recordings were made of hundreds of neurons in the rat frontal cortex and striatum, showing that decision commitment involves a rapid, coordinated transition in dynamical regime and neura...

Inferential theories are on the rise in cognitive science. But what does it mean to infer? Check out our take on inference across a variety of (neuro)cognitive systems.

Inference in (neuro)cognitive systems | 9 | Neurocognitive Foundations

Cognitive scientists ascribe inferential processes to (neuro)cognitive systems to explain many of their capacities. Since these ascriptions have different

Excited to see this now out in the world!

We identify a computational basis for how persistent underconfidence is maintained in the face of intact performance, finding that it is grounded in impaired updating of global self-beliefs from local metacognition

Super excited to share that Ven Popov & me published a new release of the #bmm R package: venpopov.github.io/bmm/

We have added the Memory Measurement Model for categorical #workingmemory tasks to the package!

Apart from that there are some minor fixes to already implemented models and functions.

Easy and Accessible Bayesian Measurement Models Using brms

Fit computational and measurement models using full Bayesian inference. The package provides a simple and accessible interface by translating complex domain-specific models into brms syntax, a powerfu...

Multiple brain activation patterns for the same perceptual decision-making task - Nature Communications

Here, the authors show the brain uses multiple activation patterns to perform the same task. Even the default mode network, which is often inactive during focus, plays a role.

This is an unlawful attack on scientific progress that puts lives at risk.
