Scientists are learning how special #brain cells play a role in detecting #illusions - and such studies could eventually reveal how #hallucinations arise, or point the way to better computer vision systems. https://www.geekwire.com/2025/laser-light-brain-cells-illusions/ HT @span AllenInstitute#Science#Neuroscience#Berkeley#AllenInstitute

Is anarchist science possible?
As an experiment, we got together a large group of computational neuroscientists from around the world to work on a single project without top down direction. Read on to find out what happened.
The project started as a tutorial on a new technique at the @CosyneMeeting 2022. We realised that the technique was easy and cheap for anyone to use with a lot of low hanging fruit.
https://neural-reckoning.github.io/cosyne-tutorial-2022/
At the tutorial we announced a 1-2 year open research project that anyone could join, starting from the materials of the tutorial, and a few starting questions we found interesting, but with no other constraints. We were inspired by the Polymath Project in mathematics.
https://en.wikipedia.org/wiki/Polymath_Project
31 people contributed to the project, joining for monthly meetings to discuss progress. All code was publicly available throughout, and when we started writing up the work in progress was also fully public. You can see that version here: https://comob-project.github.io/snn-sound-localization/paper
Not everyone who was involved made it to the paper (didn't respond or couldn't find contact details), and not all are on Mastodon, but authors include: @marcusghosh @TomasFiers
@GabrielBena @rory
We used GitHub and Jupyter notebooks to coordinate development, with a website showing everyone's current code and results to make collaboration easier. We used @mystmarkdown and GitHub actions to automate this.
https://comob-project.github.io/snn-sound-localization/
So how did it work out? Well, some things went well and others not so well. We published a paper with our results and reflections on the process. If you're interested in spiking neural networks, sound localisation, or anarchist science, check it out:
https://www.eneuro.org/content/12/7/ENEURO.0383-24.2025
Generally, the infrastructure we built worked well, as did the monthly meetings. Starting from the tutorial was a good decision because it gave everyone a common reference and meant they could easily get started.
However, the lack of direction meant that we didn't achieve very coherent results in the end. We don't think this is a catastrophic problem, but when we try again, this is something we'd like to address. If you have thoughts or would like to be involved, get in touch!
Ultimately, we didn't achieve a scientific breakthrough in this project, but we did show that without top down direction or any specific funding, we could organise a large group of scientists to work together and publish their research in a good journal. We think that's a hopeful sign for the future!

New preprint, with a modest contribution from yours truly, on proteo-transcriptomic changes in the aging mammalian brain.
New preprint, with a modest contribution from yours truly, on proteo-transcriptomic changes in the aging mammalian brain.
Presumably when Berkett says "they" she's referring to DataFarmers, as illustrated in The Social Dilemma. But it did make me stop and wonder, to what degree are fediverse apps inadvertently mirroring this relentless emotional activation, and other harmful patterns implicit in the DataFarms we're aiming to replace?
Maybe as well as accessibility - or as part of it - we need to be emphasing emotional wellness in our app designs? Eg asking whether infinite scroll is a sensible default.
Kathryn Berkett gave a talk on 'Neuroscience of Device Zombies' at TEDxTauranga;
https://www.youtube.com/watch?v=vrOddAuNau8
It was excluded from the library of TEDX talks on the official TED website, which tells you everything you need to know about their biases.

Does human episodic memory 🧠 depend on context-invariant or conjunctive coding of single neurons in the human hippocampus?
A recent TiCS (https://www.cell.com/trends/cognitive-sciences/fulltext/S1364-6613(25)00031-2) paper stimulated a very interesting debate about the nature of hippocampal coding in human episodic memory that i found very insightful.
The discussion centers around context-invariant coding of concept neurons (CN) vs. conjunctive coding of episode-specific neurons (ESN) in the hippocampus, both following different lines of thinking about the HCs involvement in episodic memory.
A short 🧵

Our primary instance is shutting down and we ended up repurposing another account however it appears that instance is unstable and may be shut down at a future date so 3rd times hopefully don't have to jump ship again for a while #introduction - Updated: 2025-08-10
We're The Weather System (Athena's Realm System), We're Trans fem, and we're an officially diagnosed autistic, bipolar and dissociative identity disorder system, we a collection of various leftist, and believe strongly in queer, and neurodiversity rights movements, we view plurality in general as neurodivergence
Our pronouns are Su/Sudo/Suselves, however She/Her/Herselves, and They/Them/Theirselves
We are most likely to toot about #Medicine, with focus on #Genetics, #Epigenetics, #Bioinformatics, and #Neuroscience giving our focus back in uni was Genetics of Human Disease, and Neuroscience but we are likely to talk about a whole range of medical topics, besides medicine we are likely to toot about #meteorology and #geology, with specific interests in #SynopticMeteorology#TropicalCyclones / #Hurricanes / #Typhoons / #TropicalStorms, #ExtratropicalCyclones, #SubtropicalCyclones, and #Tornadoes, among other topic, and we may toot about #Geology, #Minerals, and #Vulcanology, and what ever else is on our mind, we collected #MyLittlePony and are a fan of every generation of MLP, also we collect #WildManes and Radioactive stuff and play #EliteDangerous
edit extra info: [Also to note we're storm chasers, so we may occasionally post photos and media from chases, our focus is usually on Tropical Cyclones within the Australian Region Basin with mainly focus on the Coral Sea, these will usually be marked with the Tropical Cyclone and Hurricane tags]
See attached thread for System Information, System Membership 58+
Our system name is subject to change, it was previously the Athena's Realm System, however only one member, arguably two members made that decision on behalf of the entire system, without consulting us, so we're in the process of trying out system names to see which fits us best, but for the time being we will display both "Athena's Realm" and the current trialing system name so it is less confusing for those who know us by our old system name
