    #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...

    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.

    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: drive.google.com/file/d/1qmfye

    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?

    @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.
