Now accepted and published --- with many thanks to the referees for helping sharpen the manuscript. Long time since the first notes. Good to see it officially out. www.cell.com/current-biol...

A vector navigation and inference architecture can construct universal cognitive maps for abstract reasoning
Bicanski proposes an algorithm and neural mechanisms for the iterative construction of abstract cognitive maps via non-local inference. Map positions are triangulated and memorized by a set of extant ...

New preprint from my PhD at MPI CBS 🧠, with @doellerlab.bsky.social and @andrejbicanski.bsky.social “A computational model of the two dentate gyrus blades” What mechanisms allow the two DG blades to support distinct coding regimes? (www.biorxiv.org/content/10.6...) 1/9

Excited to finally share our new paper in @natcomms.nature.com: Hippocampal ripples initiate cortical dimensionality expansion for memory retrieval www.nature.com/articles/s41... With @s-michelmann.bsky.social and @doellerlab.bsky.social

Hippocampal ripples initiate cortical dimensionality expansion for memory retrieval - Nature Communications
How past experiences are reconstructed from memory remains unclear. Here the authors used intracranial EEG to show that hippocampal ripples reshape the geometry of cortical representations, supporting...

8/N: The fact that Disco captures such a diverse set of neural activity, suggests to us that discontinuity coding could reflect a key principle underlying neural activity in the subiculum. A lot more in the manuscript. We hope it will be interesting to the community.

7/N: Tracking a running average of the population activity in the sub, we find that rapid changes in the subicular population activity can signal event boundaries (temporal discontinuities), across numerous environmental configurations (including in hairpin mazes).

6/N: In purely non-spatial settings, detecting discontinuities in behavioral state (e.g., an animal’s velocity) yields neural firing along principal movement axes (Olson et al. (2017) in narrow corridors but diffusive activity in open fields.

5/N: The framework is quite general: we show predictions for 3D arenas and natural scenes. We also suggest that mixed-modality coding of spatial and non-spatial variables drives BVCs to respond to a traversable stripe on the floor.

4/N: We reproduce corner cell activity for diverse settings (concave, convex, inserted corner, cylindrical and oval arena, high and low curvature objects). Some corner cells that would normally not be classified as corner cells in experiments could map onto other reported cells.

3/N: Coded in a vector-base, discontinuities between perceived surfaces drive responses to walls, drops, objects, holes, corners, curved surfaces. Moving to 3D we get a dedicated tuning function for corner cells (Sun et al. 2024) that appears complementary to that of BVCs.

2/N: Disco accounts for seemingly disparate neural phenomena with a common organizing principle: given a continuous flow of experience, neuronal selectivity can be understood as responses to discontinuities in that flow.

1/N: Dear colleagues, I would like to share a new paper on the subiculum, part of my PhD with the Neural Computation Group @andrejbicanski.bsky.social @mpicbs.bsky.social . We present “A theory of subicular function and generalized vector coding” that we call Disco. www.biorxiv.org/content/10.6...
