Abnormal Chick Embryo (IMAGE)
Caption
In an abnormal chick embryo, the heart loops to the left-hand side and the brain also turn leftwards, forming a shape that resembles a question mark. In a normal embryo the opposite is true, i.e., the heart loops to the right-hand side and the brain also turn right. In previous work, we identified the source and magnitude of the physical force necessary to make the brain twist and discovered that the heart looping direction mechanically determines the brain twisting direction.
