The head-direction (HD) system is an essential component of the spatial navigation system and is believed to provide key signals during sleep to support memory formation in the downstream parahippocampal regions. The HD signal is processed by a mammillary-thalamic-subicular loop within the Papez circuits. Specifically, the lateral mammillary nucleus (LMN) receives an angular velocity signal from the brainstem and is believed to form an attractor network supporting the generation of the HD signal. By recording from ensembles of LMN neurons in freely moving mice during wakefulness and sleep, we
