#sfn23 — Public Fediverse posts

@Andrewpapale I don’t think so. I’m seeing the same thing - all replays don’t necessarily have a detected ripple associated to it, but the tetrodes are definitely able to detect ripples.
Of course you could say that my tetrodes are weird as well or that what I’m seeing is theta sequences… But my best guess is that ripples are just so variable that sometimes they are extremely clear and sometimes not.

Ha, here’s even an example from my #SFN23 poster which is in my corridor right now… you can see that event 603 recruits lots of cells, the raw lfp is really not in theta mode but it comes with a subthreshold ripple. I’ll add the full pic for legend.

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!

In #SFN23 discussions I realized people can have very different definitions of “planning”.

Can we try an experiment? Without looking it up (answers to this post included), can you write down the first definition of “planning” that comes to mind, and then write down your research specialty (if you are a researcher) at the end? There are no wrong answers and anyone can contribute! 🙏

#SFN23 poll: did you test positive to #Covid19 either during or after the conference?

(For context: SFN is a #Neuroscience conference with more than 20000 people and very few were masked)

Wore a mask all through #SfN23, avoided covid, only to get sick with a normal ass flu for the first time since 2019 and thats just annoying

I almost forgot about this but check this old #HippocampalReplay poll which should make more sense now in relation to my #SFN23 poster ⬇️

One of the most heartwarming moments for me was seeing two participants in the #DisabledInSTEM Mentorship Program meet up at #SfN23!

It's amazing to know that these virtual connections lead to in-person friendships!

Anyone found a way to see which of the #SFN23 poster that are in one’s “planner” have an attached poster?
So far it seems that the planner and the “virtual component” are independent? 🤔

@Raphael_Brito Ooh thank you for your questions! Not at all late and I’d still appreciate them if they were :)

1. The replay detection methods are basically like Pfeiffer & Foster 2013 - (2D) memoryless bayesian decoding on place cells putative reactivation events then detection of continuous sequences. The results shown in the poster are for swr-related replay but similar results without that constrain. Happy to share more details!

2. Very good question about the pre-reward replay events, I need to check.

3. Their contents do not seem so different from post-reward replay: strongly biased by goal, not preferring a specific path. But will dig more into it! It could be that they are forward while the postreward are backwards which would fit results from Caitlin Mallory seen at #SFN23

4. The mean (or is it median?) of 63 place cells is only for those sessions included in the replay analysis. I had a lot more that didn’t make the cut… but I have to say that you can do a lot with relatively small tetrode bundles!

Thanks and don’t hesitate to ask more!

Are you coming back from #SFN23?
Please remember to wear a mask and test yourself for #Covid19 for at least 7-10 days!

You might have it but not have symptoms and still be contagious!

I know we just finished #SFN23 but who’s coming to #Cosyne24? The abstract submission deadline is coming very soon!!

Can I just say how lovely it was to meet some of you from on here IRL this week at #SfN23???? I forget how long this mostly online world has lasted, and how I still hadn't met some folks ive been talking to for YEARS. Also my friends making friends with my other friends is one of the best things in the world and that was another blessing to see happen

After 4 days of #sfn23 many of us are beginning to experience that stage of #sfn where we feel we have learned so much that the enlightenment achieved has reached a point where we are close to lift-off...

🤣

Sorry 😁🤘

Don’t worry, #Neuroscientists who didn’t come to #SFN23: I have more FOMO being here and knowing exactly what I’m missing (because no time) than being away and not seeing any of it.
Basically, specific-FOMO hurts a lot more than vague-FOMO 😅

(Still: SFN is not finished, come see my poster at VV20 on Wed morning!)

I have presented this poster on #HippocampalReplay at #SFN23 !

I'm also uploading the poster as an image here, and it's on the SFN website: https://cattendee.abstractsonline.com/meeting/10892/presentation/33535

Little summary below:

Our goal was to investigate if replay of hippocampal #PlaceCells was indeed reflecting immediate #SpatialPlanning.

The existing literature is a little unclear: some studies find 'planning replay' and some do not. Most of the time, planning is not dissociated from reward consumption in these studies as they can generally be simplified to an alternation between two rewarded locations. In our case, we separate the location of planning from the location of reward and focus on replay happening at the planning time.

At the location of planning, we find that:

1) there is actually almost no replay at the time of planning
2) the rare 'start replay' events do NOT over-represent the future trajectory, or even the goal
3) the rare 'start replay' events do not differ for successful vs unsuccessful planning.

At the goal location, we find that:

4) Many replays occur at the goal, even before the reward delivery!
5) 'goal replays' strongly over-represent the goal (either before or after reward delivery)
6) 'goal replays' do not over-represent the current trajectory compared to the alternative trajectory, or even the optimal path if the less-optimal path was taken
7) 'goal replays' were strongly affected by errors and were quasi-absent during error trials (choosing an unrewarded end box)

In conclusion:

Reward (received or expected), but not planning, drives hippocampal replay!

Let me know if you have any questions after looking at the poster :D

Edit: updated because this is in the past now (but hoping to publish it soon!)

Great talk on astrocytes and synapse development by Cagla Eroglu right now at #SFN23. Makes me think: our training as scientists tells us we should all become neurons, but more of us need to become astrocytes for the field to be healthy.

Looking for a great poster to come see? 👀Come see ours now (Tues afternoon) at UU13 #SfN23 #SfN2023 #neuroscience @katiconen

Absolutely loved seeing manifold analysis from @mschottdorf done exactly the way it should be. Thats the kind of stuff that keeps me hanging out with the neuroscientists #SfN23

If you’re at SfN, come check out my poster this afternoon from 1-5 PM at board WW13! I’ll be sharing brand new fMRI findings from a study about how motivational states shape reward learning, choices, and memory. #sfn23 #sfn2023

As usual, charmed by all the ppl at #SfN23 sort of cautiously greeting me after only knowing me online discovering that I am actually very kind irl and not in fact always preaching a sermon of doom
