@paulgribble & @andpru and I are excited to share our latest work on how spinal circuits contribute to efficient reaching movements https://www.biorxiv.org/content/10.1101/2020.01.06.896225v1 ….
For those looking for a quick breakdown of the manuscript, this #tweeprint is for you! (1/11)
In the next exp participants made the same reaching movement and we applied the same mechanical perturbations, but we changed their arm orientation, which diametrically altered how the rotation of the wrist moved the hand towards the target. (8/11)pic.twitter.com/0RP6UDHuIe

We found that changing the arm's orientation diametrically altered how spinal reflexes in the triceps were evoked, and in such a way that were again efficiently scaled to the hand's distance from the reaching target (9/11)pic.twitter.com/534H9SrbB8

This means there is a spinal circuit that, 1) integrates info from the wrist and the elbow, 2) knows how this joint info and the arm’s orientation maps onto the hand’s movement in space, 3) produces appropriate elbow muscle activity that moves the hand to the target (10/11)

Our findings demonstrate that spinal circuits can help efficiently control the hand during dynamic reaching actions, and show that efficient and flexible motor control is not exclusively dependent on processing that occurs within supraspinal regions of the nervous system (11/11)
