How does the 🧠-map choose what to sample? Preprint: #Sweeps in #gridcells act as attention-like signal, dynamically biasing the map towards behaviourally relevant locations.

🎉 Gratulerer til vår kollega Magnar Bjørås, kåret til Årets trønder! Ved Kavli-instituttet er vi stolte over Magnars banebrytende forskning på sjeldne sykdommer som barnedemens - forskning som gir håp der det trengs aller mest. Les saken på NRK:

🧠🔬 NOK 12M to #META2P from Kavli & SINTEF! Neurophotonics PI @weijianzong.bsky.social at @kavlintnu.bsky.social is together with NorFab #MiNaLab PI Christopher Dirdal at SINTEF awarded NOK 12 million by the Research Council of Norway to develop the next generation of two-photon microscopes (1:2)

Today, Harald V King of Norway opened the Norwegian Health Association Centre for Dementia Research, at the Kavli Institute in Trondheim.

QQ11: RSC is using the HPC spatial code for good! We observed retrosplenial populations encode task structure when behaviourally relevant cues were present in a hippocampal-dependent spatial task.

QQ10: We see minute-scale population drift, not only in LEC, but also MEC and CA1 in conditions with minimal external stimuli, i.e., when mice are head-fixed on a wheel in darkness! @anelautrup.bsky.social

Poster QQ9: Theta sweeps can track moving bait and go backwards! In our poster, we describe situations in which the stereotypic left-right alternating theta sweep pattern is modulated to cover behaviorally relevant space @azvollan.bsky.social

QQ8: What drives the left–right alternation of theta sweeps? Whether a central-pattern generator (CPG)-like circuit is involved? @rajatsxn.bsky.social

QQ7: How do MEC ultraslow dynamics vary across behavioral states. In free foraging, population dynamics organize in ultraslow sequences while in NREM sleep they present as synchronous oscillations.

QQ6: By combining large high-NA objective, wide-angle MEMS scanning, SiPM detection, and multi-beam multiplexing, this new 2P miniscope (Mini10K) enables cellular-resolution imaging of thousands of neurons in freely moving mice, surpassing current FOV and throughput limits.

QQ5: What is the developmental timeline of the low-dimensional manifolds of the entorhinal cortex? Rings and tori organize at P9-P10 before major sensory-motor milestones, coinciding with other major shifts in MEC cortical dynamics. @me

QQ4: QQ4: We study population dynamics across the spatial navigation circuit as a rat moves between 4 rooms. With 4 NPX probes in CA, MEC/PaS, SUB, and dPreSUB, we see how maps switch at a fine timescale and track when each region settles into the correct representation. @jocarpenter.bsky.social

QQ3: We observe hexagonal grid cells even in environments with elevation changes! The hexagonal pattern is cleaner on the surface of a ramp and on a dome seen from above, and more distorted on a cone seen from above.

QQ2: Where are the grid cells and if so, how many? We find that grid cells form a discrete "hot spot" segregated from other functional cell types in the superficial layers of MEC and PaS. @martipof.bsky.social

Still at SfN on the last day? During the morning session on the 19th, 8:00AM - 12:00PM, come check out our posters from the Moser, Zong, and Gonzalo Cogno groups in row QQ ('Grid cells and spatially modulated cells'). Ephys, imaging, remapping, development, sweeps and more! 🧠 Detailed thread below 👇

SFN 2025 let’s gooo!! Moser group posters are held Wednesday morning (QQ), so if you’re leaving early feel free to come find us to chat :)

Thank @kavlintnu.bsky.social, the research council of Norwayfor the continues support of our work! We will provide more useful tools like #mini2p to the neuroscience!

Check out this new preprint from @clykken.bsky.social and the Moser Group: Independent phase-shifts across MEC grid modules can generate a vast diversity of hippocampal codes — revealing the mechanism that enables episodic memory. 👇

🔁 Fascinating new preprint from the Moser Group! How does the hippocampus achieve its vast memory capacity? 🧠 The answer lies in the flexible combinatorics of grid cells. 📄 Read more in the thread by @edvardmoser.bsky.social 👇

Our new paper out now in Science explores how neural activity in the lateral entorhinal cortex (LEC) *drifts* over time - and *jumps* at key boundaries - to help organize events in memory. 🔗 www.science.org/doi/10.1126/... Here's a quick summary of what we found 🧵👇

... and those jumps act like barcodes - distinct neural signatures that help the brain tag and retrieve memories. @beneuroscience.bsky.social @clykken.bsky.social @nachopolti.bsky.social @m-bmoser.bsky.social @edvardmoser.bsky.social‬ at the @kavlintnu.bsky.social

Delightful visit and dinner today in Trondheim and more tomorrow: thanks again @m-bmoser.bsky.social and @edvardmoser.bsky.social for giving me a chance to present our new data on social and sickness behavior. Looking forward to hearing more about the amazing projects at @kavlintnu.bsky.social

Thank you so much Catherine @dulaclab.bsky.social for a thought-provoking and an eminent talk today at @kavlintnu.bsky.social @edvardmoser.bsky.social

It is my great honor to host the visit of Prof. Liqun Luo at the @kavlintnu.bsky.social. The talk was so inspiring with amazingly beautiful discoveries! Thank @m-bmoser.bsky.social and @edvardmoser.bsky.social for joing the host, and Emre and Nathalie for showing the visitor the beauty of Norway:)

One of the exciting part of science is to celebrate milestones! We are super proud of Fanchon, Hien, Natalia and Aurora, our 4 MSc students who successfully graduated! Congrats once again! And good luck for what is coming next! @emreyaksi.bsky.social @inyoungj88.bsky.social @kavlintnu.bsky.social

We are thrilled to share that our freshest research group leaders Soledad Gonzalo Cogno and @weijianzong.bsky.social have been promoted to associate professors at Kavli, NTNU. Congratulations - well deserved!

Kudos to Sigrun Aasland, Norway's new Minister of Research and Higher Education @kd.regjeringen.no for recognising the global nature of science! 🌍

JOIN US LIVE TODAY for a unique art/science experience! Nobel Laureate @m-bmoser.bsky.social & the musical ensemble @trondheimsolistene.bsky.social play on our neural networks in the @embl.org #KafatosLecture "The Power of Science: Uncovering the Algorithms of the Brain" at @isfit.bsky.social

We are thrilled to announce that our #Brain-Machine-Interface team at Kavli is awarded an #NTNUdiscovery Innovation Grant of 200,000 NOK to advance algorithms in brain-machine interface! (1:3)

I was interviewed by @nature.com about the risk of talent exodus following Norway’s new language law. I hope the new government and science minister will change the internationalisation policy ASAP. @stortinget.no, @uhrno.bsky.social, @forskningspolitikk.bsky.social www.nature.com/articles/d41...
