How does the brain know what the right hand is doing?

...suggests that the brain relies on information from sensors within tissues that say how far a limb has moved. While there has been plenty of evidence that inflow plays a role, no one before has been able to show definitively that outflow is also important. Now research just published in The Journal of Physi...
