EPISODE 29: Hidden Circuits – Mapping How Worms Really Think 2025-09-24 Anuj K. Sharma – guest , Andrew M. Leifer – guest , Francesco Randi – guest , Veeren Chauhan – host , Sophie Dvali – guest Is a wiring diagram enough to understand the brain? In this episode, we dive into how researchers combined whole-brain optogenetic stimulation with calcium imaging in C. elegans to reveal functional neural connections that go beyond the traditional connectome. Key insights include: A new functional atlas built from ~23,000 neuron pair experiments How neuropeptides and extrasynaptic signals contribute to brain activity Strong functional links often exist without anatomical connections A data-driven rethinking of how neural signals propagate and integrate Implications for plasticity, brain evolution, and full-organism modelling This episode sheds light on how small brains can perform complex processing — by rewiring our assumptions about wiring. 📖 Based on the research article: “Neural signal propagation atlas of Caenorhabditis elegans” Francesco Randi, Anuj K.

EPISODE 23: Magnetic Minds – Worms Reveal Brain-Wide Signals in Real Time 2025-08-06 Uday A. Ramalingam – guest , Andrew M. Leifer – guest In this episode, we follow Caenorhabditis elegans into the magnetic field. Researchers have developed an elegant way to measure whole-brain neural activity in freely moving worms using a calcium-sensitive MRI contrast agent — a major step toward non-invasive brain mapping at the organism scale. We explore: How a genetically targeted MRI probe was used to detect calcium flux across the entire worm brain The fusion of genetics, MRI physics, and behavioural tracking Real-time measurements of brain dynamics during natural behaviour How this technique opens the door to non-invasive neuroimaging in small model organisms Implications for understanding how global brain states coordinate behaviour 📖 Based on the research article: “Functional MRI of brain-wide activity in freely moving C. elegans” Uday A.

EPISODE 21: Beyond the Wires – Worm Brains Reveal Hidden Neural Connections 2025-07-09 Anuj K. Sharma – guest , Andrew M. Leifer – guest , Francesco Randi – guest , Veeren Chauhan – host , Sophie Dvali – guest In this episode, we go beyond the famous C. elegans connectome to explore how signal propagation doesn’t always follow the wires. Using powerful whole-brain calcium imaging combined with single-cell optogenetic activation, researchers mapped over 23,000 neuron pairings to build a functional atlas that rewrites parts of the worm’s wiring diagram. We dive into: How extrasynaptic neuropeptide signalling connects neurons outside synapses The discovery of functional connections invisible in the wiring diagram How C. elegans neural signals propagate both directly and indirectly The creation of a functional connectome that predicts spontaneous activity better than anatomy alone The surprising flexibility and plasticity of even simple nervous systems 📖 Based on the research article: “Neural signal propagation atlas of Caenorhabditis elegans” Francesco Randi, Anuj K.

Event How Music Charts 2019-09-04
Viral Artists on our newest A&R Tool: Not all Platforms Are Created Equal! 2019-09-04 · 04:00 Jason Joven – host @ Chartmetric Highlights Not all breaking artists are new artists, not all platforms have the same up and comers, and not a day more should pass until you check out all the viral talent we’re discovering on our new A&R tool.Mission Good morning, it’s Jason here at Chartmetric with your 3-minute Data Dump where we upload charts, artists and playlists into your brain so you can stay up on the latest in the music data world.Chartmetric’s social media handle is Chartmetric, no “S ”- follow us on LinkedIn, Instagram, Twitter, or Facebook, and talk to us! We’d love to hear from you.DateThis is your Data Dump for Wednesday, Sept. 4, 2019.Breaking in Our Newly Updated A&R DashboardDo you like discovering new music, but you want more than just a New Music Friday playlist? Do you like discovering new music, but you don’t necessarily want to be out 7 nights a week in the clubs either?Well, come check out the next version of Chartmetric’s A&R tool, now live on the platform.The newest, shiniest updates include:Several windows of relative change….for example, there is now a 7-day, 30-day and 60-day absolute value and growth change %For example, if I click on the Instagram Followers tab, Chartmetric scans over all the IG profiles we have in our 1.7M artist database, and as of yesterday, pulled out over 38K artists who showed remarkable growtih in that particular metric.Feel-good, indiecoustica troubadour Andrew Simple comes out on top here, with a 1700% increase in his IG follower base to 8.8K, from 30 days ago.“But what if I’m not into indiecoustica?” you may say, well here’s what else is really neat about this new A&R tool version:We have established our own Chartmetric parent genre system, containing 20 major genres such as “Pop”, “Rock, Punk, Metal” and “Rap & Hip-Hop”.And once you pick that, it goes even further with the sub-genre filter, which uses over 1.8K specific genres to really get to the type of sonics you want to discover, such as “Latin jazz” or “electro swing” or if you’re really looking for it, “symphonic black metal”.If I narrow down to Rap & Hip-Hop, I get US rapper Gerald Walker as the #1, but if I apply the sub-genre “Alternative Hip-Hop”, I get Benny the Butcher as the #1 with a 21% increase himself in IG followers.“What if I’m curious about Australian artists, and I value YouTube the most?” That’s what our Artist Country filter is for, which contains virtually all the world’s countries, allowing you to surgically find artists according to the biographical data we have.And then you simply click into “YouTube Channel Views”, and there you’ll have neo-psychedelic Aussie band King Gizzard and the Lizard Wizard at #1 with a 28% increase in views in the past month.What’s a couple of cool things so far that we’ve discovered?There’s not a lot of crossover between platforms, which can open up your mind on who is doing best on which platform...and this also provides a way to focus energy once an artist hits that “breaking” threshold: Where do they need to focus their attention next?We’d also pay attention to the First Release and Last Release Columns, because a breaking artist doesn’t necessarily mean they’re a new artist.For example, Fleetwood Mac’s YouTube channel saw an increase of 6.2M views in the last 30 days and 11.5M in the last 60 days, putting them in the 10th spot, as of Sept. 2.Their first release was in the ‘60s.If you’re in the catalog game, you’re in luck, but if you’re looking for the next big thing to sign, the first release column can help you move on to other artists quickly.Much more to discover as we dig into the data ourselves, but for now, have at it and let us know what you think!Outro That’s it for your Daily Data Dump for Wednesday, Sept. 4, 2019.
