Topic: fly's compass system

A cognitive compass is a critical component of spatial navigation and path integration. Experiments in the fruit fly and recent theoretical work show that an accurate compass can be built from a handful of neurons. Many previous models have used ring attractors to model head direction systems. However, these models relied on hand-designed neural network connectivity patterns, and we lack a principled methodology for quantitatively relating connectomics data to theoretical ring attractor models. Here we introduce a novel theoretical framework for analyzing the space of threshold-linear ring a
