Thanks for the kind plug, Bene. One of many examples of @kiemohr.bsky.social 's excellence, and the lovely way visual cortex is organised certainly helps in the making of pleasing pics :)

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 ...

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.

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:

Delighted to share this paper, now published in @arvoinfo.bsky.social. With @spk3lly.bsky.social‬ and Anna Geuzebroek we explored differences in visual cortical responses for pattern pulses and pattern reversals. Here's the link:

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...

With @spk3lly.bsky.social and @neuromurphy.bsky.social, we investigated the neural computations that allow us to make near-optimal decisions in changing environments. Here's a short summary:

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.
