The video features a 3D model of a human brain that is rotating on its axis. The brain is colored in shades of blue and is set against a dark blue background. As the video progresses, white text appears over the brain, starting with "Stunted growth in children" and then adding "and mental retardation" to complete the sentence. The text is in a sans-serif font and is centered on the screen. The video does not contain any other objects or actions.
