Psycho Mind Transmission

By placing a hand on the target's head, the user will be able to enter the target's subconscious and extract any information needed, even if the target has forgotten it or has had it blocked. A special device can be used to decrease the time it takes to read the target's mind and will allow other ninja to assist. Memories that have mental blocks on them will require longer periods of time to probe through and obtain however.

Trivia

 * Nagato, through his Human Path, was also able to read minds simply by placing his hand on his target's head. This was effective as it quick and did not require any devices or machines but had the drawback of permanently extracting the victim's soul afterwards.
 * In Naruto: Shippūden episode 227, Aoba demonstrated the ability to read a targets mind without actually coming into direct physical contact with them.
