The Cortical Psychic Patch is a technology invented by Shockwave during the Great War. It is a procedure through which mind of one Transformer can be joined with another, using a cable connected directly between the two Transformers' brains.
It is used to probe one's mind, looking for secrets and true motives within the Transformer.
According to Ratchet, this device acts as a two-way conduit, when one Transformer returns to their own mind the other Transformer who leaves their own body and mind follows and occupying the other Transformer's mind.
- This device resembles Soundwave's tentacles that he has in his chest.
- Shockwave seems to use this tool quite often, since he used it in Out of the Past and in Scattered.
- In reality the patch wouldn't be much use as memory can in fact be altered.
