Marmoset Gaze Unlocks Secrets of Spatial Navigation in the Brain.
Originally Published 2 years ago — by Neuroscience News
Researchers have discovered that the common marmoset navigates its surroundings differently from previously studied rats, reflecting its unique ecological adaptations. Marmosets use visual cues, relying on rapid head-gaze shifts while stationary, and minimize head movements while navigating. In contrast, rats use low-velocity head movements and tactile whisker explorations. On a cellular level, the marmoset’s hippocampal regions show selectivity for 3D view and head direction, suggesting that gaze, not place, is key to their spatial navigation.
