Cortical psychic patch

Cortical psychic patches are a technology from the Transformers: Prime portion of the Aligned continuity family.

Now, where to hang this doohickey...

The Decepticons developed the cortical psychic patch during the Great War. It is a procedure through which the mind of one Transformer can be joined with another, using a cable connected directly between the two Transformers' brains. The procedure was banned by the Autobots, though there are a substantial number of texts on the subject available to interested Autobot medics.

Fiction

Prime cartoon

With Optimus Prime infected with cybonic plague and time short, Ratchet decided to try the procedure, though he had never previously attempted it himself. He talked Arcee through setting up a cortical psychic patch between Bumblebee and Megatron, who at the time was lying comatose in the Decepticon warship. The procedure succeeded, inserting Bumblebee into the replication of Kaon constructed by Megatron's subconscious, and Bumblebee was able to interact with Megatron and retrieve the formula for the plague cure. Arcee then disconnected the patch, but Megatron was able to use the dying connection to jump into Bumblebee's head. Sick Mind Megatron subsequently returned to the Nemesis in Bumblebee's body and used the patch to return to his own form as he revived it with a shard of Dark Energon. Out of His Head

Notes

• The cortical psychic patch resembles Soundwave's tentacles, though thinner.
