We collected ~4.7 hours of task data on 3 participants, listening to 10 different categories to create a functional gradient space in which we could situate category structure, and infer acoustic and semantic dimensions.

🧠🔊 New preprint!
How does the brain organise natural sound categories?
In our new fMRI study, we show that auditory cortex arranges sounds along continuous functional gradients, where acoustic and semantic structure are integrated into a shared representational space.

Auditory Cortical Gradients Integrate Bottom-Up and Top-Down Structure During Natural Sound Categorisation
Understanding how the brain organises natural categories is a central challenge in neuroscience. While prior work has shown that categories can be decoded from distributed activity patterns in auditor...

I worked with Jonny for 5 years during my formative years as a scientist. He influenced how I see life deeply. Although I won't hear him explain things to me again, his words and kindness will live through those whom he inspired. We were so lucky to have him in our lives. We miss you a lot, Jonny.
Jonny Smallwood @themindwanders.bsky.social was a beloved friend and mentor. He was taken from us too soon. His was a beautiful mind who understood the beauty of minds. As ever before, his kind voice guides me and his work will continue. We miss you Jonny. www.cbs.mpg.de/news/obituar...

Just to be clear this is not something we can tell from this study and any suggestion that it might be seems dangerous to me.
Stimulants rescue cognition and brain functional architecture if you didn’t sleep enough … short term: www.biorxiv.org/content/10.1... Is it possible that this is a true rescue, or is it just a temporary cover up and there will be a price to pay … maybe decades later? Asking for a friend.

This accumulating process has been obvious since at least 2021. I assumed Labour would reluctantly intervene to help. That they won't almost guarantees that UK academia will become an even more cruel/anti-intellectual place to work, even for those in RG universities. So I'm leaving.
At the start of this government there was lots of talk about ending the war on universities. But now the crude rhetoric about "ivory towers" has started up again.
Yet there are a whole bunch of things government could do to avoid a disaster without spending huge sums.

The end of the mass university era in England and Wales is now base case in my view after the last week. Much of Blue Labour, much of Britain's Right and a great number of voters will welcome that. But it's an interesting and arresting example of minoritarian state policy capture.

Ultra-processed food increases risk of early death, international study finds
About 14% of premature deaths in England attributable to unhealthy food, the most among surveyed countries
Consuming large amounts of ultra-processed food (UPF) increases the risk of an early death, according to a international study that has reignited calls for a crackdown on UPF.
Each 10% extra intake of UPF, such as bread, cakes and ready meals, increases someone’s risk of dying before they reach 75 by 3%, according to research in countries including the US and England. Continue reading...
