Preparing some slides on my favourite topic of the moment - #HippocampalReplay - for some colleagues, starting from lecture slides I made about 8 years ago...
and I keep crossing stuff or adding "BUT see xx" or "actually not" or "Now controversial!" to about half of the results that I was taking from granted 8 years ago 👀Is there any such thing as a scientific fact?!

Here's a very interesting paper from the #KeinathLab:
In the absence of task or reward, #PlaceCells appear to reflect the past history of behavioural biases, i.e. the accumulated past paths taken by each individual mouse. I am actually starting to think that #HippocampalReplay is doing a similar thing - just reflecting an average of the individual's past behaviour, and that all supposed "coding" of reward is purely driven by this (notice how reward "coding" always seems to happen in cases where reward biases the behavioural patterns..) 👀🧠🤔

If you want to study #HippocampalReplay... Use ephys, not #CalciumImaging!!
(Calcium imaging doesn't detect single spikes well, but replay mostly involves single spikes)

Heading off to the #EBBS2025 conference in Bordeaux!
I will present a poster there on our latest #HippocampalReplay findings (replay does not do planning, but seems to support reward-learning instead, in a flexible spatial planning task), and co-lead a symposium with the great John Widloski, also on replay!
We have an amazing speaker list with John himself, Lisa Genzel, Jacob Bakermans and Elisa Massi!Check the full programme here: https://ebbs2025.azuleon.org/programme_overview
Will you be there?!

This paper ⬆️ from Caitlin Mallory is now out in Science! Great to see a #HippocampalReplay paper there, and very well deserved!
The time course and organization of hippocampal replay
From #FosterLab, maybe soon the #MalloryLab?? -

A short commentary by the great Anna Gillespie on awake replay:
Ruminating on replay during the awake state
#GillespieLab (https://www.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
Related: history of the 'genesis' of #ThetaSequences narrated in this retrospective by @adredish: Mental Time Travel: A Retrospective
(original post:
https://neuromatch.social/@adredish/113662497894186335) #RedishLabI'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!

Just co-submitted a #Symposium proposal for #EBBS25! Yes it's on #HippocampalReplay and we got an amazing speaker line-up, I hope it gets in 🤞
(It's my first...) -

Hi #Neuroscientists, do you know someone working on #HippocampalReplay (either experimentally or computationally) who might want to go to #EBBS25 (it's in Bordeaux, France)?
I'm thinking about submitting a symposium proposal and don't want to be biased towards only people I already know.. 🙏

#JournalClub on Closed-loop modulation of remote hippocampal representations with neurofeedback, from #FrankLab: little summary + comments.
- The goal is to see if rats can deliberately reactivate internal representations, without external cues.
- The authors design a closed-loop system that does clusterless real-time decoding of position and rewards the rats when they reactivate a specific maze arm end.
- The rats go through a gradual training process: first getting reward on the actual maze (a T-maze), then getting reward in the home box when they orient towards the target arm of the maze [head-direction task], then getting reward in the home box when they reactivate the representation of the target maze end [neurofeedback task].
- The rat's performance is not too bad given the difficulty of the task, kudos to Rat2 who seemed to really know what he was doing.
- interestingly, the reactivations do not happen during #SharpWaveRipples, and not really during theta either, just during an uncharacterised LFP state.
- Little caveat 1: as far as I can see, the head-direction of the rats is not shown in any plot and it is not possible to say if the rats might still be doing the head-direction task during the neurofeedback task. That being said, the rats clearly reactivate the target arm more in the neurofeedback than head-direction task, which is quite convincing.
Little caveat 2: the performance is always shown in terms of total rewards collected, and not reward rate. So in different sessions rats might reach the maximum reward but take twice the time. Showing reward rate would be more informative.
conclusion: this is pretty cool, but we would really need to know about the head-direction.
question for the audience: what do you think the rats "think about" during those reactivation moments??

New preprint from Caitlin Mallory / #FosterLab about #HippocampalReplay and its links with the #MedialEntorhinalCortex - looks really cool!!
Self-avoidance dominates the selection of hippocampal replay

@mrspaghetti @dlevenstein looks pretty cool, thanks for sharing!

@PhiloNeuroScie looks very interesting - thanks for sharing!!
I wonder how related it is to this recent paper from the #BendorLab: The role of experience in prioritizing hippocampal replay -

Reading two very interesting articles for #JournalClub:
- Replay of incidentally encoded episodic memories in the rat
(spoiler alert: it’s not actually about replay as in hippocampal replay) - Hippocampal sequences span experience relative to rewards
(this one is about #HippocampalReplay)
also, not that anybody cares but I met first author Mari Sosa for the first time at #SFN23 and it was so great to finally see her IRL! I wish she was on here!

“One month left to submit abstracts for the hippocampus green meeting
http://hippocampusgreen.net/wp/
Join us for this 2-day conference focusing on hippocampal physiology, network dynamics, and the phenomenon of replay in freely behaving animal models (London, June 10-11, 2024)”Looks pretty cool! If only I could plan my life that far in advance 😅
