Fair point! Perhaps Stoßlüften should be exported as part of a package deal, alongside universal double glazing and proper insulation.

House burping: should we all adopt this German habit? It’s a simple way to keep homes fresh and mould-free, and has caught on in the US. But there are a few potential downsides ...

Here is the link to the Guardian article

𝗦𝘁𝗿𝗮𝗵𝗹𝘂𝗻𝗴𝘀𝗸ä𝗹𝘁𝗲 (noun) 𝘭𝘪𝘵. 𝘳𝘢𝘥𝘪𝘢𝘵𝘪𝘰𝘯 𝘤𝘰𝘭𝘥

A form of cold felt even though the air is warm, explained in physically plausible terms by reference to cold walls and surfaces; a key concept in couples’ negotiations over the thermostat.

The ritualised act of opening all windows at once; a universal cure for any malaise, whether or not caused by "stickige Luft" (stuffy air)

𝗭𝘂𝗴 / 𝗭𝘂𝗴𝗹𝘂𝗳𝘁 (noun), 𝘭𝘪𝘵. 𝘥𝘳𝘢𝘶𝘨𝘩𝘵

A moving current of air perceptible only to the trained perceiver; proven to cause colds, neck stiffness and headaches. Its detection ('es zieht') requires immediate corrective action.

Glad to read in the Guardian today that some German concepts central to indoor wellbeing are becoming more widely appreciated 😅

Read on for a short glossary on indoor climate for those living with people raised in Germany

I was so busy conferencing that I only took one photo on arrival!

Wonderful to see old friends, make new ones, and talk bottomless science.

My goal for ACNP 2027: make it onto the @ahmarilab.bsky.social #fashionsOfAcnp feed 😀

For anyone who made it through the “Everything was better back then” moments of the holiday season:

Reward sensitivity declines with age.

That might explain why apples tasted like apples, music felt real, and TV was just better.

LinkedIn got my thoughtful 2025 year-in-review reflection.

Bluesky gets the stupidest thing I did in 2022:

Booking travel to a conference in Maine, happily thinking “Cool, there’s a direct flight from London to Portland.”

New preprint from the lab!
A frontal motor circuit for economic decisions and actions:
www.biorxiv.org/content/10.6...

We use a novel task in mice, cortex-wide imaging and optogenetics, NPX recording and modelling to reveal a circuit mechanism that transforms abstract decisions to spatial actions.

Thank you! I could not have done this without the idea, initiative and incredible support of the Public Engagement Team at the Crick @crick.ac.uk , they really made it happen 😊

Ready for a crash course in psychosis?

My recent public lecture is now on YouTube! I explain what psychosis is, what we are doing about it in the lab, and what the future may hold.

A slide titled “Summary Hallucination-Like Perception (HALIP)” with four bullet points on the right: “HALIP increases after hallucinogenic manipulations in mice,” “HALIP correlates with hallucinations in humans,” “Striatal dopamine causally mediates HALIP,” and “Expectations link striatal dopamine and HALIP.” On the left are four icons illustrating each point: a mouse hearing a sound, a human wearing headphones, a dopamine D2 receptor graphic, and a schematic of Bayesian inference with overlapping prior and likelihood curves. A large magenta arrow points toward the Bayesian schematic.

I somewhere heard the term #Bayesplaining 😂

I confess: guilty as charged. Exhibit A: my slide.

A view of the ArcelorMittal Orbit in London, a tall red looping steel sculpture with a long enclosed slide spiralling around it. The photo is taken from street level with a tree in the foreground and a cloudy sky in the background.

One great thing about having kids: you do all the fun things you would never do otherwise – and your body immediately reminds you why 😅

Still, the 45-second slide ride down this #London sculpture tower, the ArcelorMittal Orbit, was absolutely worth the stiff neck!

What would Francis Crick make of this?

I really enjoyed being part of this conversation on consciousness with @anilseth.bsky.social @stevefleming.bsky.social @cosmicskeptic.bsky.social, hosted by @profbriancox.bsky.social. Listen now!

In case it makes you feel better, here is an excerpt from my recent breakfast conversation: "Mom, don't say that! This is so 2023!"

How often have you heard that schizophrenia is “80% genetic”?

That number is almost certainly too high because it comes from twin studies that overestimate heritabilty.

Great explainer of this phenomenon👇

Highlighting the human side of science can only make science better.

So, I still don’t have a clear answer for how best to navigate the tension between structural sexism and personal effectiveness and well-being.

But humanity is probably part of the solution.

Scientists also want to be humans.

The reversed Finkbeiner approach addresses this by talking about male scientists in a way that would fail the Finkbeiner test if it was a female scientist.

That resonates much better with me because...

I have considered applying the Finkbeiner Test to how I think and talk about other scientists - and myself. But it never felt quite right, because…
