The head direction (HD) system functions as the brain's compass, forming our inner representation of the external world. Single HD neurons increase their firing rate when the head of an animal is oriented in a specific direction. The HD signal is internally generated, driven by vestibular information and it is anchored to stable visual cues in the environment. How specific brain microcircuits combine the stable maintenance of the HD signal as well as flexibility upon reorientation is unknown. Our goal is to understand the dynamical structure of the head direction neural network in the presubic
