🛫Arrived in Montreal without my luggage but with a brand new cerebellar atlas in tow! Learn how it predicts functional boundaries, localizes regions in the individual, and opens doors to a wide array of applications.

Join me at my talk tomorrow!

⏰ Mon 8:20 AM
🗓️Cerebellar Symposium
📍Room 510

To relate it to my recent couple of #cerebellum posts, this paper by the same folks is pretty amazing (if you like this sort of thing)

"Does the Cerebellum Implement or Select Geometries? A Speculative Note" https://www.researchgate.net/profile/Christophe-Habas/publication/338692807_Does_the_Cerebellum_Implement_or_Select_Geometries_A_Speculative_Note/links/5e2833b3a6fdcc70a141171f/Does-the-Cerebellum-Implement-or-Select-Geometries-A-Speculative-Note.pdf

Using @3Brain's high-resolution #biointerface technology, Monteverdi et al. unveiled a significant frequency dependence and spatial #anisotropy in cerebellar network processing, expanding our current understanding of these complex #circuits.

Wow, that's impressive: cerebellar cross-sections for 56 mammalian species, and data showing that "Ancestral estimations indicate that size and folding of the cerebrum and cerebellum increase and decrease concertedly through evolution."

"Diversity and evolution of cerebellar folding in mammals", by Heuer et al. 2023 https://www.biorxiv.org/content/10.1101/2022.12.30.522292v2

Question: does the pachyderm's (elephant) cerebellum also follow the proportionality rule with the cerebrum? I recall a commentary (Herculano-Houzel https://doi.org/10.1016/j.cub.2022.01.058 ) on how the elephant's cerebellum is 96% of all brain cells, when normally it's "only" 80%, at least in primates.

Processes in the #cerebellum are involved in various #diseases that affect motor learning. A new tool developed by a Bochum working group helps to investigate this better: a light-activated protein that is coupled with part of an exciting receptor.

First, by ‘current neural state’ I just mean r, the input set of firing rates to whatever store of synaptic weights we are assuming, W (I tend to assume this is the #cerebellum but that is not a critical assumption).

#introduction : I am a #neuroscientist studying #3dvision in freely moving humans (lots of 3D researchers study static humans or freely moving rats). I am excited by the #cerebellum (which is computionally huge but hard to study electrophysiologically), less so by the #hippocampus (which has been studied in immense detail but may, in the end, have a more minor computational role). I follow #NeuroAI as #machinelearning and #reinforcementlearning may solve the brain, en passant, before we do.

My first Pouet will be to wish everyone a very happy New Year 2023, hoping to see people fighting for freedom and democracy win and the world become a better place for everybody !
I will take this opportunity to introduce myself: I am a neurobiologist interested in #brain #development #synapses and #cerebellum. My team has currently several job openings, check it out ! www.fekrijeselimilab.com

I’m a bit late to the game, but now out, in a more final form: https://www.nature.com/articles/s41586-022-05471-w

Tri Nguyen, @lathomas42, and our team #cerebellum found neurons sample inputs redundantly and selectively in ways that may help make the network more robust with a minimal loss of encoding capacity.

#neuroscience #connectomics #neuralNetworks

@albertcardona Thank you for so kindly describing Tri Nguyen’s and @lathomas42’s paper. Indeed, Purkinje cells are amongst the most “elegant and luxurious” #neurons extracted out of our EM data.

Folks can see more for themselves here: https://github.com/htem/cb2_project_analysis

#neuroscience #connectomics #cerebellum

One of the two first authors, Logan Thomas @lathomas42 is on mastodon, as is the senior author Wei Lee @darbly. Welcome! And what a spectacular paper on #cerebellum #connectomics. Those must be the prettiest Purkinje cell renderings since the century-old famous ones from Cajal. This time with synapses though!

"Structured cerebellar connectivity supports resilient pattern separation" Nguyen, Thomas et al. in @darbly's lab https://www.nature.com/articles/s41586-022-05471-w

Spectacular work based on connectomic reconstruction from nanometre-resolution volume electron microscopy and computational modelling that contributes novel findings in cerebellar microcircuitry:

"both the input and output layers of the circuit exhibit redundant and selective connectivity motifs, which contrast with prevailing models. Numerical simulations suggest that these redundant, non-random connectivity motifs increase the resilience to noise at a negligible cost to the overall encoding capacity. This work reveals how neuronal network structure can support a trade-off between encoding capacity and redundancy, unveiling principles of biological network architecture with implications for the design of artificial neural networks."
