What causes the torque? Does it have to do with blood pressure being slightly higher on the heart's side of the body or something like that?

- uj8efdkjfdshf 7y agoGiven that the rostral (head) end of the neural tube literally bends inward (cephalic flexure) as it grows into the enclosed space of the head to later become the brain, and that the tip is also attached to a clump of cells that will become the heart (cardiac anlage) which is also migrating downwards with the tip of the neural tube and to the left side of the chest, it is altogether unsurprising that the brain should be slightly pulled to the left.
- blueprint 7y agoThe articles doesn't indicate if research is sufficiently advanced to have established the time that torquing occurs but given that it's associated strongly with handedness, it seems reasonable to consider it likely that the torquing develops during the stage of increase neural plasticity during normal childhood development. I wonder if the torque balances out if a person later develops ambidextrousness.
