New #fMRI + #ComputationalModel #NeuroPaper by #SummerfieldLab:

Goal-seeking compresses neural codes for space in the human hippocampus and orbitofrontal cortex

Potentially very interesting #NeuroPaper in #Humans:
Backbone spiking sequence as a basis for preplay, replay, and default states in human cortex

(Thanks to my colleague Hung-Tu for highlighting this one!)

(I’m not sure we can really say that preplay has been “robustly demonstrated” in rodents though…)

A key idea behind the brain's ability to #flexibly and #rapidly #compute is its #shortterm #plasticity ! The mechanism was beautifully reviewed by the late Mark Stokes:

‘Activity-silent’ working memory in prefrontal cortex: a dynamic coding framework

Seeing ideas like these included in modern #ML models more and more now - extremely exciting to see how this will work out in #technology !

New #Neuroscience paper, with potential implications for the pyramidal-cell specificity of some #Optogenetic stimulations:

“our results challenge the use of CaMKIIα promoter-driven protein expression as a selective tool in targeting cortical glutamatergic neurons using viral vectors”

CaMKIIα Promoter-Controlled Circuit Manipulations Target Both Pyramidal Cells and Inhibitory Interneurons in Cortical Networks

New review on the “spatial cells” across different species! Looks very interesting:
Neural mechanisms for spatial cognition across vertebrates
Vinepinsky & Segev 2023

Small but important comment: it is perfectly normal for place cells to have multiple #PlaceFields ! Only in very small environments (<80cm diameter) will you mostly see single-field place cells. The single field is probably more the exception than the rule in the natural world.

⤴️​ After reading this #NeuroPaper I have to say it is much more interesting than what I thought at first view! And particularly well-written, illustrated and clear!

A must-read for anyone interested in #Dopamine #ReinforcementLearning #Reward #Value #RewardPredictionError #Navigation #Shortcuts #Detours #CognitiveMap (maybe) #Inference with some future hints of #HippocampalReplay !
Congrats to all authors, let me know if any is on here!

@shaneomara Did you see this?

Hot off the press! 🔥​
https://doi.org/10.1016/j.neubiorev.2023.105042

We performed a meta-analysis of neuroimaging studies looking at interpersonal neural synchronization (INS) and contextualized the results using diverse public databases to develop new hypotheses on physiological processes potentially involved in INS.

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!! ✍️​

@kendmiller @NicoleCRust
Since we can combine hashtags in searches, pinned hashtags etc. I vote for #NeuroPaper whenever we’re referring to… a paper in neuroscience, and simply add the #Thread if it’s also a thread?
Also if it’s a preprint thread it could be #MastoPrint but preprints and papers are really not that different nowadays…

For neuro paper threads: sigmoid.social/about/more has already claimed #PaperThread and #NewPaper (the latter announcing a paper without a thread) for the AI community. I enjoy seeing their papers too, but we need a distinct tag for neuro papers. For a thread, somebody suggested a #TootSuite, and I had suggested a #MastoPiece, but maybe we want something simple like #NeuroPaperThread and #NeuroNewPaper? or mix and match, like #NeuroSuite for a thread and #NeuroPaper for a paper w/o a thread?? Decisions, decisions.

I nominate @NicoleCRust to be the hashtag czar. Decide for us Nicole! (And anyone else, weigh in to help inform our czar!) And from your lips, or at least typing fingers, to the Mastodon's ears ...
