Philippa Johnson

Two flagship papers from the International Brain Laboratory, now out in ‪@Nature.com‬:
🧠 Brain-wide map of neural activity during complex behaviour: doi.org/10.1038/s41586-025-09235-0
🧠 Brain-wide representations of prior information in mouse decision-making: doi.org/10.1038/s41586-025-09226-1 +

A great example of engagement with open peer review 👇

Thanks! I'll share it once it materialises :)

Interested in finding out what causes you to disengage from a task? Catch my talk about the dynamics of arousal and engagement at #CCN2025 @cogcompneuro.bsky.social today at 11! You'll find me in room C1.04, and Friday afternoon at poster C168.

@isabellehoxha.bsky.social rocking her first #CCN2025 poster on her work with @stepalminteri.bsky.social on range adaptation.

Stay tuned for her second poster on Friday afternoon, and @phil-johnson.bsky.social’ talk on Thursday!

Finally the Version of Record of our paper "Criterion placement threatens the construct validity of neural measures of consciousness" is out in @elife.bsky.social as *fundamental* and *compelling*!

New paper out in @plosbiology.org w/ Charlie, @phil-johnson.bsky.social, Ella, and Hinze 🎉

We track moving stimuli via EEG, find evidence that motion is extrapolated across distinct stages of processing + show how this effect may emerge from a simple synaptic learning rule!

To celebrate the defence of my PhD, and thanks to
@ibbamsterdam.bsky.social, I will host a symposium titled "Vision as prediction: learning, action, and biases" on June 6. Program, registration and more information here: bit.ly/43reOgR

Against Language Barriers: A Call to Protect International Education in Dutch Academia

An open letter supporting the international bachelor’s psychology programs threatened for cuts. Proceeding with these cuts would damage some of the most important and impactful psychology departments globally. #supportdutchpsychology

Cutting international bachelor programs threatens psychological science » Eiko Fried Two days ago, four Dutch universities announced discontinuing their English-speaking psychology bachelor programs (1, 2). I will briefly explain (1) how this decision came to be, (2) why this is such ...

Four large Dutch universities, including Leiden University where I work, have decided to throw international psychology bachelor programs under the bus in an effort to appease the rightwing government.

Here's my blog why this is a terrible idea.

I'm looking for a public dataset of young+older people doing a simple perceptual decision-making task, with sufficient trial + subject numbers. Ideally, multiple stimulus difficulty levels but no manipulations (conditions, task switching etc).

This must exist - tips for where to look? 🧒👨‍🦳🧠

Coding best practice Q:

Multiple people are analyzing the same data, stored on an internal server. What is a good way to store local paths pointing to the data? This is what we have now - there are probably better/cleaner ways

🎉 Our paper "Criterion placement threatens the construct validity of neural measures of consciousness" is now out in eLife! 🎉
TL;DR: Both simulations and empirical data show that you should not post-hoc sort neural data based on subjective measures of consciousness.

this is a good paper. and I have absolutely no relationship with the author #hirethisstranger

How do research groups keep track of the various papers they read and discuss, and ideas that arise? We love 'literature blitz' meetings and learn a lot, but then often the discussions stay in each of our heads.

Zotero group libraries? Other solutions? #newPI
