SOURCE: SCIENCE DAILY PSYCHOLOGY FEEDTITLE: Stress can scramble your brain’s internal GPS, MRI study finds
URL: https://www.sciencedaily.com/releases/2026/08/260807035151.htm
Stress may literally scramble the brain’s internal GPS. Researchers found that cortisol, a hormone released during stress, made people significantly worse at navigating a virtual environment and disrupted the precise activity of grid cells, specialized brain cells that help us understand where we are in space. When landmarks were missing, this navigation system nearly stopped functioning, while another brain region appeared to step in and compensate.

…During pursuit, sweeps narrow and track a moving target; after sudden target changes, they reorient before the animal turns; during backward locomotion, they reverse; and even during #REM sleep, sweep structure is modulated.
A fascinating view of #ThetaSweeps as an attention-like mechanism for querying #CognitiveMaps in real time.

Finally out, and this sounds like a beautiful one from the Moser lab: New #Science paper (unfortunately behind a paywall💰) on #ThetaSweeps in the #entorhinal-#hippocampal #navigation circuit. In #rats 🧭🐀, these #theta-locked sweeps are not fixed scanning patterns, but can be rapidly redirected toward #behaviorally relevant locations. …

🧠 New preprint by Guardamagna et al.: Using large-scale recordings in #rat pups, the authors show that toroidal #manifolds in #MEC emerge by P10, before eye and ear opening, upright gait, and active exploration. Ring-like manifolds appear even earlier, by P9. External spatial experience seems to align these preconfigured internal maps only later, as pups begin to navigate.

Which of these famous "spatial cell" type is better?
Well, which is your favourite anyway? Yes it's a silly question

Very cool retrospective AND review of the hippocampal #SpatialCognition field from Neil Burgess:

@PennamitePLR If you love hexagons you should love #GridCells ! (neurons, seen for example in Rats, that activate in a very regular hexagonal pattern as the rat explores an environment)

@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

I love #GridCells but I have to say their influence for any neural process is probably highly over-inflated.
When you actually record from #MEC you see there are so many non-grid cells… it’s really a huge contrast to #Hippocampus where most of the cells are going to be #PlaceCells either in the current environment or another.

A little summary of #Neuroscience-related hashtags?
(Please add any you think of in answer and I’ll edit the list).#NeuroArt
.#Neuroscientist / #Neuroscientists
.#NeuroRat (yep, I’m pretty much the only one using this one)The cell types:
.#PlaceCells / #GridCells / #HeadDirectionCells / #SplitterCells … (give me more)And then we have the brain regions:
.#Hippocampus / #Striatum / #RetrosplenialCortex / #Cortex / #Cerebellum / …
Bonus:
.# NeuroBuzz: once a post takes off, anyone can add it as an answer and then the author can edit it in the original post (but don’t add it when writing the original post, that’s cheating) -

In case this is useful for anyone out here - new tools for Bayesian analysis of grid cell activity (with the benefits of efficiently evaluating covariates and avoiding binning): https://arxiv.org/abs/2303.17217

@TrackingActions Excellent dispatch! Let's tag with #neuroscience #GridCells #hippocampus so it appears on those who follow this tags, and also becomes easier to find in the future.

New review on the “spatial cells” across different species! Looks very interesting:
Neural mechanisms for spatial cognition across vertebrates
Vinepinsky & Segev 2023Small but important comment: it is perfectly normal for place cells to have multiple #PlaceFields ! Only in very small environments (<80cm diameter) will you mostly see single-field place cells. The single field is probably more the exception than the rule in the natural world.

⤵️4/5 Why P2 ‘Grid cells in a 3D lattice’:
- Wireless recordings of 2D-verified #GridCells, in 3D!
- Rats climb around for >1h while foraging for paste (for in-depth analysis of behaviour, see: https://link.springer.com/article/10.1007/s10071-020-01432-w)
- Grid cells, although spatially stable, do not have 3D grid patterns! Just randomly-distributed fields.
- This disagrees with many model predictions!
- Head-direction coding is preserved in 3D!
