Looking for #neuroscience? Or #Celegans? or #Drosophila? Or #connectomics? Or #brains, #entomology, #academia, #nativebees? Different place, different approaches – tags here are useful and can be followed.
For accounts, @PhiloNeuroSci selects and comments on neuroscience papers; @eLife and @PLOSBiology publish their papers and digests.
@NicoleCRust challenges us all often; @matrig and @kristinmbranson publish at the intersection of neuroscience and computer science; John @tuthill, @BorisBarbour, Jason Shepherd @jasonsynaptic , @mtarr @gepasi, @cian, @schoppik, @MatteoCarandini, Dan Goodman @neuralreckoning, Bryan @BWJones, @achterbrain, @CoriBargmann and many others publish on neuroscience among other topics.
On open access and #ScientificPublishing there's Stephen Eglen @sje, Stephen Royle @clathrin
I am living many out ... the list is long. One way to find them is via tags like #neuroscience.
Big accounts like Doctorow @pluralistic, @Carl_Zimmer, @jwz, and @timkmak are here too. There are many more.
There are useful bots like, for me, @flypapers – I wish I could filter for neuro-only papers, but the volume isn't high. Then there're neuroscience-specific servers like synapse.cafe and neuromatch.social – their local timelines may reveal further accounts you may like.

Do you think that hippocampal #Replay can truly represent a future planning trajectory?
Or that all replay trajectories are actually related to consolidation / generalization / other memory-oriented mechanisms?
Discussion & questions welcome!

We are hiring a new postdoc in cerebellar imaging! Come join the imaging group that is most serious and obsessed about the most irrelevant (according to some) part of the brain :-)
@NicoleCRust
I think some of the most exciting ideas in neuroscience start out as half-baked ideas that where 'not even wrong'.
But I think we should have a time-limit on them. 5 years I'd say. If a new idea still doesn't make any testable prediction after 5 years of being written about and discussed, maybe it wasn't such a good idea after all.
My prime example: "The cerebellum is a forward model for motor control and cognition". A really cool idea, influential, and has motivated tons of experiments. However, it has also become clear that without additional specifying assumptions the idea in itself does not make actual predictions - or can 'predict' anything.
So we need to stop pretending that "cerebellum is a forward model" is a theory - it's not. It's a hazy make-me-feel-good notion that may become testable with additional assumptions - and it is those assumption that form the real theory.
Mind blown yesterday by George Sugihara, who explained that variables can causally influence one another but also be uncorrelated. It happens with a Lorenz attractor, where variables flip between correlated and anticorrelated (so no net correlation). Video here:
https://www.youtube.com/watch?v=6i57udsPKms
These types of mirage correlations that come and go also happens in the wild - such as in the factors that combine to form the red tide and in gene expression networks.
The recording of this VVTNS talk is now up on youtube: https://www.youtube.com/watch?v=bb6i6gLRdlg. I was lucky to be afforded 50 min to present our results about how the brain architecture can support flexible, efficient & robust internally-driven motor control. A big thank you to the organizers of wwtns.online, David Hansel and Ran Darshan!
For those who may be interested, I'm lucky & honored to talk at the Van Vreeswijk Theoretical Neuroscience Seminar
tomorrow 11/01 at 11 AM EST. Instructions to join: https://wwtns.online. Thanks to the longer format, I'll be able to dive deeper into the topic. I'm looking forward to the discussion!
Hi all 😃
Our latest #Review on #SplitterCells is now published in @eLife !!
I will probably write a real thread on it when I get a chance... for now:
link: https://elifesciences.org/articles/82357
why: some neurons in the #Hippocampus (and other brain regions) of #Rats (and other mammals) have the fascinating ability to discriminate not just different presents, but different past or future states or trajectories in the same current situation. They could be related to #EpisodicMemory or #DecisionMaking 🤔They are called 'trajectory-dependent cells' or Splitter Cells. 🔀 We tried to make sense of them!
what: Hippocampal Splitter cells do a lot of puzzling stuff. For example there's a lot of them even in tasks that do not require the Hippocampus to be solved. They spread asymmetrically on a linear track leading to a choice point - 'past' splitters around the start and 'future' splitters towards the choice point. #TimeCells cells can be splitter cells (but they're usually #PlaceCells). Splitter cells evolve with experience, or maybe it is performance, nobody really knows. ⁉️ ... and a lot more weird stuff
conclusion: Two different computational models, the temporal context model and the latent state model, each explain a subset of the properties of splitter cells... so perhaps the Hippocampus implements both! But more experiments are needed to disentangle them 😄
now what: questions or comments? Please let us know!! ✍️

In our new project we show typical structural & functional #neuroscience motifs like modularity, small-worldness, functional clusters, mixed selectivity & efficiency emerge in these spatially-embedded RNNs
