Interested in how we make preference-driven decisions, and how this is implemented in the brain?
We report that neural correlates of evidence accumulation (CPP, Mu/Beta) are also observed during value-based decisions.

Tracing the neural trajectories of evidence accumulation and motor preparation processes during voluntary decisions
Voluntary decisions have previously been described by where they arise in the brain and how actions corresponding to one's choice are prepared. However, the processes by which these internally guided ...

Check out our new multisensory decision study!
We tackle a decades-old Q: does faster detection of bimodal targets come from a race or co-activation between modalities? And also a vital, orthogonal Q: is it one decision process or two?
A1: co-activation
A2: two!

New paper from the lab indicates some surprising differences in visual cortical contributions to two popular VEP types.
In it, Kieran uses some of his brilliant tricks from last year's paper:

Neurally-informed modelling unravels a single evidence accumulation process for choices and subsequent confidence reports
Subjective confidence in perceptual choices depends on computations occurring prior to and after choice commitment. However, the nature of these computations remains unclear. Current models disagree o...

A little temporal integration or leaky evidence accumulation might be all that's needed to explain subjective aspects of stimulus detection like perceived duration or confidence. New comp. modelling preprint from *Ramla Msheik* with Emma Sirouet, @spk3lly.bsky.social and @nfaivre.bsky.social.
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!
