An interactive notebook for the NEUR0016 lecture Path integration, continuous attractors and grid cells. A ring of cells with local excitation and global inhibition forms a single bump of activity. Use the sliders to make it drift, jump and move with a velocity input, the link to path integration.

The notebook runs entirely in your web browser; nothing is installed and no data is sent to a server. The first load downloads about 30 MB and may take around 30 seconds.
Download the notebook (.ipynb) to run it in your own Jupyter installation (it needs NumPy, Matplotlib and ipywidgets).
