Hey neuro-folks ! Check out my poster on stability and uncertainty in the HD system this Thursday (27 March) at CoSyNE 2025 ! Would love to chat neuroscience:) !

Attending @cosynemeeting.bsky.social? Check out @tonyzador.bsky.social’s account of what motivated him to launch the meeting 30-plus years ago, and why cross-disciplinary conferences are so important.

The origins of COSYNE: Building a community
Thirty years ago, theoretical and experimental neuroscientists rarely went to the same conferences. So I helped launch a meeting to get them talking.

Excited to share our latest paper: “Phase Precession Relative to Turning Angle in Theta-Modulated Head Direction Cells” together with Dr. Eleonora Lomi (co-first author) Prof. @katejj.bsky.social Prof. Anna Mitchell and Prof. @neilburgess10.bsky.social

Phase Precession Relative to Turning Angle in Theta‐Modulated Head Direction Cells
Grid and place cells typically fire at progressively earlier phases within each cycle of the theta rhythm as rodents run across their firing fields, a phenomenon known as theta phase precession. Here...

We’ve all had one… but we’re still grateful for everything they’ve taught us.

How do different sensory signals combine in the computation of cognitive maps? I’m thrilled to share our new preprint, in which we investigate this question in the context of the head-direction system:

Joint visual-vestibular computation of head direction and reflexive eye movement
Several cognitive maps have been identified, but what sensory signals drive them and how these are combined are not well understood. One such map, the head-direction representation, is believed to be ...

1/3 How does visual input affect the heading direction (HD) network?

In our latest lab preprint, Ryosuke presents "visual landmarks" to larval zebrafish and shows that the HD network tethers to the visual environment. The experiments are again inspired by the beautiful recent work in Drosophila.

Did you know that Claude Shannon also developed maze solving algorithms?

Which he implemented physically using a wooden mouse named Theseus.

To solve a given maze, on a grid, Theseus used two modes:
