How widespread are our memories stored in the brain? Our new study, open access in @NatureNeuro, investigates how category learning changes neuronal representations in mouse visual cortical areas. (1/8) @mpi_neuro @sandra_tanja @t_bonhoeffer @MHuebener doi.org/10.1038/s41593…

Starting in a couple of minutes, don’t miss it 😊 @sandra_tanja @MPIforBI

In case you haven't seen it yet, the poster session still lasts another 45 minutes! Great work from @daniellepaynter @MPIforBI

It’s spring in the Murnauer Moos, flowers everywhere!

Training doesn’t have to be slow. 303km/h, ok @DB_Bahn, you’ve definitely made your point 😊

Scientists of Twitter! The world needs more reminders that we're living, breathing human beings. I was tempted to post a picture of me doing not-science, but my spouse confirmed that no one wants to see a picture of me napping on a weekend afternoon.

Curious about how maps form in the visual system? Check out our new preprint “Retinal origin of orientation but not direction selective maps in the superior colliculus” biorxiv.org/cgi/content/sh…, led by @DMalmazet and me, with @Chen___Li. @FarrowLab @__NERF @BiologyKULeuven 1/5

@KentaM_Hagihara @DavidLaubender @t_bonhoeffer @MPIforBI Anyway, hope this explains it a bit better. We ofc can think of further possibilities for these structures not having been observed before, but we think these are the most likely. If you like to discuss in more detail, just reach out, would be happy to 😀

@KentaM_Hagihara @DavidLaubender @t_bonhoeffer @MPIforBI By identifying ipsi-clusters using local density of only ipsi-eye preferring neurons (thus focusing on binoc V1) we work around this effect of the monoc/binoc division. However, this method requires a large number of ipsi-preferring cels in a single fov/volume to work reliably.

Check out our latest preprint on ocular dominance columns, which we have found in mouse visual cortex!biorxiv.org/content/10.110… @DavidLaubender @t_bonhoeffer Mark Hübener @MPIforBI #bioRxiv

@KentaM_Hagihara @DavidLaubender @t_bonhoeffer @MPIforBI Ah, right, like in the rat (Laing er al. 2015) 😀We did think about it, and it would indeed be interesting, but haven’t tried that (yet)

@xpieter @DavidLaubender @t_bonhoeffer @MPIforBI Interesting. Have you by chance tried retro-labeling callosal-projecting neurons and overlayed with those "columns"?

@TrackingActions Thanks 😀 And good question! We suspect because we looked at L4 (instead of L2/3; inspired by work of the Olavarria lab in rat), imaged a large part of binoc V1, lots of neurons, and variability across animals (see e.g. figs S2 and S5).

Wow! How was this missed before?! Excited to dig in, nice work 🔥⬇️
