Vision plays a crucial role in instructing the brain’s spatial navigation systems. In the absence of vision, the remaining sensory systems attempt to fill in the previously dominated role of vision. However, how the brain’s navigational system is affected, as well as the strategies it adapts to facilitate spatial awareness following vision loss remains an open question. To explore this, we recorded from head direction (HD) cells in the anterior dorsal nucleus (ADn) of the thalamus in freely moving sighted and blind animals. First, we found that both congenitally blind and late-onset blind anim
