Evidence of optimal control theory over active inference in corticospinal excitability modulations

Show abstract
Two theories, optimal control theory and active inference, dominate the motor control field. We use transcranial magnetic stimulation (TMS) in force and angle tasks to examine whether corticospinal excitability represents a motor command, as proposed by the optimal control theory, or a proprioceptive prediction, as proposed by active inference. Our results strongly support optimal control theory. We encourage comparisons of the theories against each other based on empirically testable predictions.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
