  1. A short commentary by the great Anna Gillespie on awake replay:

    Ruminating on replay during the awake state

    #GillespieLab (gillespie-lab.com/)

    Interesting bits:

    "replay during sleep is generally thought to occur in the forward direction"

    I believe this is true too, but has anyone actually analyzed it? It could be done on several existing datasets...

    "The idea that awake replay might serve a planning role was broadly adopted by the field, even though direct experimental evidence [...] has been slow to emerge"

    YES because replay is not related to immediate planning, however nice it would be if it was

    "We, as a field, also need to be more precise with our terminology. For instance, what exactly should we consider evidence of ‘planning’ or ‘deliberation’ in an animal model? "

    YES

    I'd actually argue that replay, and not theta sequences, might be closer to mental time-travel... but we probably don't know enough about either to be sure yet!

  6. #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?

  7. @Andrewpapale for sure, the #RedishLab has pioneered a lot of discoveries. Replications / extensions of results are good though! I want to read these in details and then we could maybe ask the first author John to present at a special #JournalClub!!
