A canonical input to the head direction compass carries predominantly eye movement signals

This study challenges the canonical view of the nucleus prepositus hypoglossi as an angular head velocity relay by showing its neurons predominantly encode eye movements rather than head motion.

Recurrent connections enable point attractor dynamics and dimensionality reduction in a connectome-constrained model of the insect learning center

The paper investigates the computational role of recurrent connections in the insect mushroom body using a connectome-constrained model, finding they enable point attractor dynamics and dimensionality reduction.

Online learning for orientation estimation during translation in an insect ring attractor network

The paper develops a neural model constrained by insect connectivity to perform sensor fusion and online learning for orientation estimation during translation, showing its viability in robotic systems.

Spatial theta cells in competitive burst synchronization networks: Reference frames from phase codes

The paper investigates spatial theta cells in rats to explore how temporal phase codes anchor spatial representations to external reference frames through burst synchronization and competitive learning.
