Primes¶
- Efference Copy
- And when prediction fails, the unattenuated residual is seen: this is why a system whose eye muscles are paralysed and tries to move them perceives the world as shifting — the command copy predicts a sweep that the failed effector never produced.
This sourceStates the reafference principle — efference copy cancels the predicted self-caused (reafferent) signal, so a paralysed eye that issues a movement command perceives the world as shifting.

Mechanisms¶
- Corollary Discharge Pathway
- This is the classical reafference principle: the nervous system tells self-caused stimulation apart from world-caused stimulation by comparing incoming signals against a retained copy of the outgoing command.
This sourceDefines the reafference principle as comparing incoming sensory signals with a retained copy of the outgoing motor command to distinguish self-caused from world-caused stimulation.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. Neither this nor any other of the 2 citations of this work carries a recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
