Do neighboring #PlaceCells in #Hippocampus CA1 map neighboring locations in space? 🧠🗺️
Is there micro-scale spatial topography in the hippocampus?

Do #PlaceCells that sit next to each other also represent nearby places in the world? 🧠🤝🗺️

Place cells in CA1 lack topographical organization of firing locations | PNAS Topography is a well-described and well-known concept for cortical organization in primary sensory and motor cortices of mammalian brains. Similar ...

A half-century old question may have its final answer. Using high-resolution #Mini2P microscopes, we find no evidence of local topography in #PlaceCells. Place fields of neighbouring cells are no more similar than those of randomly selected cells. 🧠🗺️ Out now in @pnas.org www.pnas.org/doi/10.1073/...

Theta sweeps are population sequences in #gridcells and #placecells that, once per theta cycle, radiate outward from the animal’s location. In baseline conditions, they alternate rigidly left-right around the head axis, generating broad, forward-oriented sampling of nearby #space. (2/6) 🧠🧹

Emulation as a behavioral strategy underlying spatial observational learning in rats Humans and several non-human species have shown the ability to learn by observing an experimented conspecific. A basic form of this learning is spatia…

Nice paper from Fuentealba et al. (2025) looking at the involvement of hippocampus in the emulation of conspecifics: www.sciencedirect.com/science/arti...

Learning place cells and remapping by decoding the cognitive map Border cells are sufficient to generate place cells and remapping during path integration in artificial neural networks, challenging the role of grid cells for spatial navigation.

New research in eLife challenges some long-held ideas about place cells and grid cells and suggests a powerful border-to-place cell pathway for navigation.

Hippocampal representations drift in stable multisensory environments - Nature Tracking of individual place cells in mouse CA1 shows that representational drift is not influenced by changes in environment or behaviour, and is lower for more excitable place cells.

I’m excited to share my final co-first author paper from my postdoc in Dan Dombeck's lab!

We explored how behavior, senses, and neurons influence how much information in the brain changes over time.

A Cellular Basis For Mapping Behavioural Structure with Tim Behrens YouTube video by Kempner Institute at Harvard University

In the latest #KempnerInstitute talk, @behrenstimb.bsky.social of @ox.ac.uk explains how a class of ‘goal-progress' cells in mouse prefrontal cortex serves as a schema for mapping behavior. Watch the talk: youtu.be/JGwyHXigSQc #PFC #memory #placecells #brain
