A Fine Balance

Caption: V3 neurons (shown in green) relay signals from the nerve cells in the spinal cord to motor neurons (shown in blue), which cause muscles to contract (points of contact shown in yellow). In addition to establishing a balance between both sides of the body, V3 neurons ensure that the stepping rhythm is robust and well-organized.
