Sometimes you wonder why the labs with all the funding (not just this one! This is just one example) do not do slightly more risky experiments instead of rediscovering the wheel.. 🤔 This is something anyone who records in hippocampus has observed and there's even specific papers about it.

Place cells in CA1 lack topographical organization of firing locations

See for example Redish et al., 2001: Independence of Firing Correlates of Anatomically Proximate Hippocampal Pyramidal Cells from @adredish (at least it is cited)

Our paper on the poor replicability of Tolman, Richie & Kalish, 1946 - the famous "Sunburst maze" - is out!

Last author @rmgrieves made a very nice thread about it here:
https://fediscience.org/@rmgrieves/115844897663215766

The article: Tolman's Sunburst Maze 80 Years on: A Meta-Analysis Reveals Poor Replicability and Little Evidence for Shortcutting

I'll just add that this doesn't at all question the #CognitiveMap theory, which is quite strongly supported by diverse lines of evidence - but it shows that one of the elements previously used to support the theory, the ability to choose a shortcut over unexplored space, is not that clearly demonstrated!

Importantly, this also shows that it is crucial to consider papers in their context and to make sure results are consistently replicable before changing them into scientific facts!

PS: I managed to attract Roddy to Mastodon - it would be great to show him we can get at least as much interaction on here as with his similar thread on Bluesky

My colleague asks what is a good and easy-to-use software to create and run #VirtualReality experiments in humans?
Something that works with one of those VR headsets, but ideally would also work on a normal computer screen in a non VR version... Their experience with coding is mostly with Matlab... Any suggestions?

For our next #NeuroESC #JournalClub I will read this paper from @jessetm :

Flexible decision-making is related to strategy learning, vicarious trial and error, and medial prefrontal rhythms during spatial set-shifting

get the PDF at: https://drive.google.com/file/d/1qmfyeNkOwe_R-tvCOc0uSq3AX2WkMt4I/view?usp=sharing

Anyone else interested? We could all pledge to read it and then discuss it here afterwards (Next Friday) 👀

#VTE detection: what's the best algorithm out there to detect Rat VTEs from 2D head position data (no HD data)?
By "best" I mean least effortful for the user...

I know that @adredish has the D-phil method (explained in Interactions between deliberation and delay-discounting in rats #RedishLab which is used quite a lot.

But also just found out about a different method from @jessetm explained in A Machine Learning Approach for Detecting Vicarious Trial and Error Behaviors #MizumoriLab - Jesse, I haven't checked the details yet but as its creator, would you recommend it? Would you have code for it somewhere? I couldn't see a repo link in the paper but maybe I missed it. 🙏

Edit: Jeff Stott added this one to the list, which uses a "Curvature" measure (also from #RedishLab): A functional difference in information processing between orbitofrontal cortex and ventral striatum during decision-making behaviour

Any other ones out there?
#Neuroscience #NeuroMethods #SpatialCognition

@elduvelle_neuro

Mice definitely do #VTE (Vicarious Trial and Error) behaviors. We've seen them in our Restaurant Row task. (Take a look at the various @BrianMSweis papers. They VTE in the offer zone as they learn to precommit to avoid the sunk costs.)

Primates do as well, but in primates they are generally saccade-fixate-saccade sequences rather than actual head movements.

#DecisionMaking #SpatialCognition

The #Tolman "sunburst maze" results (from 1946) are often used to demonstrate shortcut ability in rats... but do they really? More on this later!

For now, would you know of any #ComputationalModels that were tested in this protocol (whether they replicate the original results or not)? We know of a few (well... 4) but would like to make sure we are not missing any.

#BehaviouralNeuroscience #SpatialCognition #Shortcuts #CognitiveMap #Neuroscience (kind of)

#SpatialCognition question: any studies that show that if you learn a response (e.g. "turn left at choice point) in one environment, you are more likely to repeat this response in a new environment?

So, "response #generalisation" ?

I'm pretty sure this is a thing but can't find a good study to cite about it...

#SpatialNavigation #Neuroscience

Paper resubmitted! ✅ 🤞It's a review about the #Tolman #Sunburst maze and how, despite many attempts, its results have not been consistently replicated (at all)... And no, the light is not really the problem!
I'll post a thread when / if it comes out!

Written with Roddy Grieves in the #NeuroESC lab!

People who use rats in #SpatialCognition tasks, or decision-making tasks, which strain do you prefer? 🐀

(Ideally, please comment on why!)
(Multiple choices possible if you really have to)

#NeuroRats #Neuroscience #SpatialNavigation

Anyone knows of researchers that compare #Mice and #Rats behaviour (ideally in complex tasks)? It could be in #SpatialCognition but also in other fields. Papers that directly compare both species would also be great.

If you want to study #HippocampalReplay... Use ephys, not #CalciumImaging!!

I contributed a little bit to this methods paper now published in #eNeuro :
Adapt-A-Maze: An Open-Source Adaptable and Automated Rodent Behavior Maze System - my contribution is mostly about the automated, pneumatic door system, as you may know, doors are my thing 😉 🚪

First author Blake Porter from the #JadhavLab did a great job putting everything together in an easily-useable format and, for once, I will link to Bluesky with his nice thread on it: https://bsky.app/profile/blakep-neuro.bsky.social/post/3lms56kaj3k2x

If you ever try to implement it in your own lab, let me know!

#PlaceCells often have elongated place fields next to an environment's boundaries.
Is there any paper where this phenomenon is directly predicted by the #SuccessorRepresentation model of place cells?

#SpatialCognition #Neuroscience #Hippocampus

#NeuroESC #JournalClub
Reading Mental exploration of future choices during immobility theta oscillations

If you've read it, will you let me know what you think?

The authors look at #ThetaSequences in a working memory task in a radial arm maze. They find theta during immobility (makes sense, e.g. we saw that in our two-goals task). They also find that theta sequences might preferentially represent the next goal (also makes sense, e.g. Hippocampal theta sequences reflect current goals)!

I have only done a quick reading so far, but am confused by a few points:

• the decoding is done on all cells (pyramidals and interneurons), shouldn't it be done on pyramidal or #PlaceCells only?
• the cell counts are quite low (often less than 40 pyrs) when I would have thought at least 50 place cells would be needed for this kind of maze. I guess that shows that #Neuropixels are not the best to record from dCA1!

• the decoded algorithm itself includes a ' position transition matrix' which seems like it would bias decoding towards realistic trajectories that the rat is about to do??? (but I probably missed something)

• also, this study is very related to this other paper, which is not discussed or even cited (😕 ):
  Assembly Responses of Hippocampal CA1 Place Cells Predict Learned Behavior in Goal-Directed Spatial Tasks on the Radial Eight-Arm Maze #CsisvariLab

With the current situation in the #US, several of my former colleagues there are looking for a #PostDocJob in #Europe, to do #BehaviouralNeuroscience or #ComputationalNeuroscience in #SpatialCognition (or adjacent).
Lots of hashtags I know..

Do you know a #EU or #UK #Neuroscience lab looking to hire a postdoc in these fields? Let me know and I'll pass it on to them!

Edit: adding #RodentResearch and #humanresearch for the species concerned (in this case)

Yoo-hoo we received our new #SpikeGadgets order!!
It has all we need to do 128ch and 32ch wired or wireless recordings!!

For context this is in my new lab at the #UniversityOfGlasgow (apparently we might be the only ones in the UK to use SpikeGadgets ?!?!) with Roddy Grieves as PI! Our lab name is #NeuroeSC for #Neuroethology and #SpatialCognition 😁

#SpatialCognition question: do we know if #Mice do #VTEs (Vicarious trial-and-error)? Or is it specific to rats? Maybe it hasn’t really be tested yet but that would be surprising.. anyone has a video?

Tagging @adredish in the hope that he will know
