ATNR: kinesiology geekiness

That's Asymmetric Tonic Neck Reflex for all you lay folk. It is a primitive reflex that biases motor neurons towards extension on the side of the body that the head is turned toward. AKA, she sticks her arm out in the direction she is facing. Watch when I turn her head the other way, she flexes the left arm and extends the right.  Erica is a pro.
