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:

Very happy to share this new paper, published in @elife.bsky.social, the last one stemming from a PhD chapter 🥲. In it, @spk3lly.bsky.social and I show that an early V1 signal (the C1) can have direct influence on a perceptual decision.

Pressure to use genAI for #ECR is quite high, I feel it weekly... ethical, ecological, economical, privacy- and cognitive-related worries keeps me from joining that ship.
I need more time to research not something that creates the illusion of reasoning, if that costs grants or positions, let it be.
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!

Check out our new paper which isolates a human brain signal that specifically tracks the growing urgency to commit to a choice pubmed.ncbi.nlm.nih.gov/41611534/. This one was a long time coming! Sterling work from @harveymccone.bsky.social and a bunch of past lab members!

How does the brain adjust its decision processes to ensure timely decision completion? Computational modelling and electrophysiological investigations have pointed to dynamic 'urgency' processes that serve to progressively reduce the quantity of evidence required to reach choice commitment as time e …

In this article, Egan et al. examine multisensory evidence accumulation and show that evidence in two modalities sub-additively co-activate a single, thresholded motor process.
Egan et al. examine multisensory evidence accumulation and show that auditory and visual evidence is accumulated in distinct processes during multisensory detection, and cumulative evidence in the two modalities sub-additively co-activates a single, thresholded motor process.
