⤴️ What are good reviews that explain the differences between #Replay and #ThetaSequences ?
Do post your own!

I'd recommend, as the most recent I know which addresses both: (Decoding the cognitive map: ensemble hippocampal sequences and decision making)[https://www.sciencedirect.com/science/article/pii/S0959438814002025] by Wikenheiser & @adredish .
Also really like the figures in (Hippocampal ripples and memory consolidation)[https://www.sciencedirect.com/science/article/pii/S0959438811000316] (yes, a bit old).
​Will post others as I come up with them but I also count on you!

So... what are the differences between #ThetaSequences and #Replay (in the rodent #Hippocampus ?

Here is an illustration from real data!

Fig 1 shows ~70 #PlaceCells firing while a rat runs on a maze to reach a reward. See how the activity is different between running and pausing?
Fig 2 shows possible theta sequences.
Fig 3 shows possible replay.

Spot the differences & check alt text for more info!

PS: (very simple) #Matlab code to plot this is available here !

We are also unaware of any reports of reactivation events that contain representations of a trajectory that leads to a location of immobility followed by a trajectory that leads away from the location

Interesting, and probably true, right? Why is that? Related to the spatial chunking of #ThetaSequences?

@mrspaghetti Super interesting!!
Does it affect “basic” behaviour in any way (running speed, number /duration of pauses, rearing etc.)?
Does it affect #SplitterCell coding?
Does it affect #ThetaSequences?!
