2023: 8,039 proposals 2024: 10,360 proposals 2025: 17,066 proposals 2026: 21,627 proposals Something's gotta give

Iva Vukušić@vukusiciva.bsky.social

This ridiculous number of applications is, in my view, the result of 2 nightmare developments happening concurrently 1.the precariousness of the job market for young PhD graduates which then fuels further: 2.the AI tools enabling overproduction of proposals. #Research #ERC #ResearchFunding #Academia

Inside the rehearsal room of A ROOM WITH A VIEW. A smart new adaptation of Forster’s great novel of love and discovery. 3 Oct - 1 Nov Novel by E.M Forster Adapted by Grace Chapple Directed by Hannah Goodwin Co-produced with Melbourne Theatre Company & Black Swan State Theatre Company

As my Australian friends come visit the UK for conferences and the like, my partner returns home for rehearsals of an adaptation she’s written for the stage: E. M. Forster’s ‘A Room With a View’, set to tour the country this year! Here’s a fun little behind the scenes (@belvoirst.bsky.social):

If an action results in error, each neuron requires an individualized teaching signal that guides change in its output. This is the credit assignment problem of learning. Are there neurons in the brain that can compute such a sophisticated teaching signal? Yes. www.biorxiv.org/content/10.6...

The hippocampus sits at the interface of perception & memory, allowing us to link past, present, & future through its role in generating predictions. Excited to share this theme issue in @royalsociety.org's Philosophical Transactions B, co-edited with @barense.bsky.social & @mariamaly.bsky.social

🏰 New preprint! 🏰 (w/ the excellent @neuronomist.bsky.social & Prof. Jason Mattingley) For my PhD I've been using EEG, psychophysics and modelling to explore how the brain uses uncertainty to balance sensory information against expectations about what's out there. 🧵1/n

Introducing @brisepsi.bsky.social - we're an experimental psychology initiative run by grad students in Brisbane (Meanjin) across UQ & QUT 🧠 We host a monthly dose of freshly baked research (students, ECRs, & bigwigs) followed by social goodness. Help us grow with a follow! 🤗 #neuroskyence

'to treat peer review as a throughput problem is to misunderstand what is at stake. Review is not simply a production stage in the research pipeline; it is one of the few remaining spaces where the scientific community talks to itself.' 1/3

Our publishing system does not prioritise or value the careful curation of research data to be FAIR nearly enough. I have been data editing for AP&P for a year now, and it is sad to see no reward for the clearly careful organisation of data and materials vs that which is thrown on OSF with no care!

Also, I apologise for the poor figure quality in the HTML version of the article. Elsevier’s typesetting team made some nonsense changes that I did not consent to, which have somehow proved to be frustrating to fix on their end. The PDF version is fine though!

Perhaps the coolest result was that these surprise signals were *shared across attributes*. That is, classifiers trained to decode surprise for shape could reliably do so for colour (and vice versa), after accounting for latency shifts.

We first looked at the evoked responses and found classic effects of adaptation via the constant vs. change sequence comparisons. This said, we found no evidence for visual surprise after controlling for cortical adaptation (i.e., when comparing surprising changes to neutral changes).

Interestingly, we were still able to decode multivariate whole-scalpe representations of surprise (neutral vs. violation) separately for each attribute. Moreover, these signals were reliable from ~250 ms, suggesting that surprise is predominantly signalled after the initial feedforward sweep.

But when does the visual system signal surprise? And do the dynamics of a surprise signal depend on which attributes (features) violate a prediction? This is important to think about, given the functionally segregated organisation of the visual system.

Here, we recorded EEG from participants who viewed sequences of a bound object that changed in either colour or shape over four steps. Crucially, the contexts of these changes were designed to appear random (and unsurprising) or violate the established trajectory (and cause surprise).

Predictive coding theories assert that the brain uses prior knowledge when resolving percepts. Deviations between what is predicted and sensed generate surprise signals (so-called ‘prediction errors’), which calibrate the relevant erroneous predictions.

And it was an absolute treat to run! Thanks everyone who attended :) #ACNS2025
