Continuous attractor networks support various cognitive functions yet the neuronal dynamics and circuits supporting these dynamics in vivo remain unclear. The HD circuit is a canonical example of such network and HD cells each fire for a specific direction of the animal’s head. In the anterodorsal nucleus of the thalamus (ADn), HD cells maintain their mutual coordination during sleep, when sensory inputs are virtually absent, supporting the view of an attractor-driven system. The rigid organization of HD cell activity in the ADN begs the question of the origin of these structured patterns. Th

Continuous attractor networks are believed to support various cognitive functions, from working memory to spatial representations, yet the neuronal dynamics and circuits supporting these dynamics in vivo remain unclear. One example of such networks is the head-direction (HD) circuit, a crucial signal for navigation. It is represented by HD cells, which each fire for a specific direction of the animal’s head, and is transmitted to the cortex by the anterodorsal nucleus (ADN) of the thalamus where a vast majority of neurons are modulated by HD. ADn HD cells maintain their mutual coordination dur
