@mattnolan Good points… still, when rats do foraging in 2D, they can have very nice grid cells, but as soon as they move on to 3D, still foraging, the grids break down… 🤔
Roddy (from Grieves et al 2021 says that he’s not aware of any continuous attractor model of grid cells that has been extended to 3D but there should be 2 options: 1) either the grids can integrate movements in the z-axis and that should give rise to columns in 3D, or 2) they can’t and the grid should completely break down in 3D. However, the data showed mostly randomly-located spatial fields that were more spatially-stable than chance, so neither of those 🤔 (similar findings by Ginosar et al., 2021 but for MEC cells that were not necessarily grid cells). But maybe there are now more recent CAN models that we are not aware of!
This reminds me that Gily has a new review paper on the role of #GridCells for #Navigation that I #Need2Read: Ginosar et al., 2023

Thalamic nucleus reuniens coordinates prefrontal-hippocampal synchrony to suppress extinguished fear
(Me, reading the title:
“suppress extinguished fear”… 🤔
“suppress extinguished fear” 👀
“suppress extinguished fear…?” 🫨 )Despite the disruption of my mind, this seems really interesting! #Need2Read

Ooh this seems very interesting:
Lost in time: Relocating the perception of duration outside the brain by #RobbeLab (not on here right?)
#Time #TimeEstimation #RatBehaviour #PlaceCells #TimeCells (added those last two because they seem clearly linked to the contents even though I don’t know if they’re actually discussed)I did a time-estimation experiment and yes, some of the rats did develop these kind of superstitions… like standing at the delay zone… Not all of them though, at least not that we could see! And time cells seem to tell us that they do have some internal representation of time passed… also if time is actually space does it mean that the #TemporalContexModel is actually a MovementContextModel? @marcwhoward you might be interested in this…

Time or distance: predictive coding of Hippocampal cells
We show that the type of experiment determined the cells’ encoding, such that in fixed-distance experiments distance-encoding cells dominated, while on fixed-time experiments time-encoding cells dominated.
Seems very interesting! But is it surprising? Place cells are known to encode what is consistent and disregard what is not… 🤔
