Cortical psychic patch

Shockwave 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. By this means, the victim's memories can be viewed by both parties, allowing information to be extracted, though it appears to be a read-only arrangement. 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
Shockwave used a cortical psychic patch to extract decryption codes from Arcee's mind, thus informing the Decepticons of the Autobots' new home on Earth. Out of the Past
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
Megatron successfully learned the purpose of the Omega Keys by using a patch to view Smokescreen's memories. Inside Job
Another patch proved useful when Megatron wanted to find out Starscream's true motives, as he was able to replay Starscream's own memories. Though when the memories started to incriminate him as well, Knock Out was tempted to prematurely disconnect the link, trapping Megatron in Starscream's head, and was only stopped by Dreadwing. Patch
A patch used on Wheeljack by Shockwave failed to yield any useful information on the whereabouts of the scattered Autobots, as Wheeljack didn't know anything. Scattered Shockwave used a patch to try to extract information from Ratchet on how to complete the Synthetic Energon formula but failed as the doctor didn't know how to complete it any more than the Decepticons did. Persuasion
Cyberverse cartoon

In an attempt to help the amnesiac Bumblebee regain his memories, Windblade used a cortical psychic patch to enter his mind. However, the process failed and subjected the Autobots to extreme pain before rendering them unconscious. It also emitted a powerful energy pulse that attracted the attention of nearby Decepticons Thundercracker and Nova Storm. Fractured Upon defeating the Seekers, the two Autobots managed to locate and board their ship, where Windblade managed to successfully use the cortical psychic patch to enter her friend's mind by using the ship itself as extra computing power. Memory Following this, Windblade and Bumblebee made regular use of the cortical psychic patch to tap into Bumblebee's mind and attempt to access his memories.
Notes
- The cortical psychic patch in Prime resembles Soundwave's tentacles, though thinner, with the appendages being based on his live-action counterpart's.
