Yes, good luck! 🙌

Awesome project!! 🐊

Very cool project!!

Is there any chance this will be available online / as a stream?

Preeeeetty cool

Nice safe!!

QQ13: We can functionally identify monosynaptic input cells to the CA3 and DG subfields of the hippocampus by combining transgenic mouse lines, a modified rabies virus, and in vivo imaging with a head-mounted 2-photon miniscope. @rijacobsen.bsky.social

QQ12: Obenhaus et al. are presenting results on functionally mapping isochronic populations (cells born around the same time during embryonic development) and show how birth date shapes functional properties of cells in MEC! octoscience.bsky.social

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

I have so many issues with this podcast with @earlkmiller.bsky.social . I think that this podcast nicely shows why I have trouble with such approaches. Lets go through some of the claims.

For the first time ever, INSS will have a booth at SfN this year. Please come and say hello at Booth #3327
Would be lovely to see some familiar faces!

A neural state space for episodic memories Episodic memories are highly dynamic and change in nonlinear ways over time. This dynamism is not captured by existing systems consolidation theories …

I wrote a thing on episodic memory and systems consolidation. I hope you all enjoy it and/or find it interesting.

Yeah!! Looks beautiful!

Huge congratulations to the @BrainGlobe.info team for winning the 2025 International Prize awarded by the @theneuro.bsky.social and Helga Cooper Foundation Open Science Prizes Selection Committee 🎉

Insect spatial memory is thought to be based on panoramic snapshots that are modelled as retinotopic images. This idea won't allow a distinction of landmarks from the scene. Unexpectedly, our data suggest that 🐝 learn 3D-objects as individual landmarks. #neuroethology

How can the brain create countless unique memories using a single, universal metric of space? We’ve been waiting for the answer to this for two decades!

Wow wow wow, congratulations @clykken.bsky.social and team!!! This is cool.

8x8 grid depicting the approach to stimulus creation. Feature pairs are on the axes and images are in the cells. The x-axis represents the high-level feature pairs: setting (green) and object (teal). For example, the first column of images all depict “truck” (object) in “field” (setting) rendered in various textures and patterns. The y-axis represents low-level feature pairs: texture (blue) and pattern (purple). For example, the first row of images all depict different objects and settings rendered as if drawn with crayon (texture) and containing large horizontal edges (pattern).

Excited to release the SPOT grid: a new image set that factorially crosses scene-object & texture-pattern pairings.

We hope these stimuli will be useful to researchers aiming to (partially) disentangle the contributions of lower- and higher-level visual features to behavior & brain activity.

Coherent dynamics of thalamic head-direction neurons irrespective of input While the thalamus is known to relay and modulate sensory signals to the cortex, whether it also participates in active computation and intrinsic signal generation remains unresolved. The anterodorsal...

🚨New preprint alert!

The thalamus has long been seen as a relay of sensory signals to cortex.
But could it also generate its own structured activity?
Our study explores this question in the head-direction (HD) system.

Some explanation 🧵👇 1/13

Check our new preprint where we examine how enriched experiences alter synaptic connectivity and coding sparsity across the neocortex.

Impressive design!! Repeatability and precision are shown in sample microscopy stage and by laser->fiber coupling. Check it out.

MARBLE: interpretable representations of neural population dynamics using geometric deep learning - Nature Methods MARBLE uses geometric deep learning to map dynamics such as neural activity into a latent representation, which can then be used to decode the neural activity or compare it across systems.

Great question, and exactly what I’m interested in. Stay tuned for further news (:
