Head direction (HD) cells can fire selectively as a function of the animal's head azimuth direction and form an internal compass for navigation. They were found in the mammalian limbic system including the dorsal presubiculum and entorhinal cortex. The underlying network updates its directional estimate in a self-organized fashion and can be recalibrated by external sensory cues....

Signed responses from readers of the wire.
No actionable change — this computational modeling study is too basic and preliminary to inform clinical vestibular or audiology practice.
Understanding how the brain encodes spatial direction at a computational level may eventually inform vestibular rehabilitation research, but no near-term clinical translation is evident.
