It became fascinating to me to watch twins in NICU, usually side by side in their own isolettes. The Oxygen sat monitor would alarm on one for low sats and instantly the other would alarm for the same low sat. So I’d sit and watch them. Heart rate monitors, respirations and sats would be within a point of each other. How did they do that?
With mirror twins, one will put his left arm over his head and the other will do it with his right arm. One would bend his left leg and the other his right leg.
If you doubt me, watch identical twins in the stroller at a shopping mall. Fascinating.
Very Right Brain behavior.
