Abstract

Efference copies of movement-inducing neural signals have been proposed to serve a role in gaze stabilization. Prior work has demonstrated a spino-extraocular motor circuit in the tadpole that relays copies of spinal commands to extraocular motor neurons. A recent study demonstrates the presence of this circuitry in mice, suggesting a unique method of gaze stabilization in the locomoting mouse.
