Grid Cells

Grid cells are neurons in the entorhinal cortex that fire in a triangular lattice pattern as an animal navigates space. They are thought to provide the neural substrate for path integration, the brain's ability to track position through self-motion.

This demo visualises a continuous attractor network model of grid cells using a twisted torus topology. As you move in the square arena, the activity "bump" on the torus moves accordingly. The red dots show where a randomly chosen grid cell fires, revealing the characteristic triangular lattice that emerges from the toroidal geometry.

PhD student at the University of Edinburgh

I study how neural networks in the brain perform computation. For my PhD, I investigate spatial computations in the entorhinal cortex. In my free time, I work on open-source software for neuroscience.

I was a NeuroAI intern at Cold Spring Harbor Laboratory.
I was a NeuroRSE intern at the Flatiron Institute.
I run a lot.
