Telepathic circuits The telepathic circuitry ( AUDIO : " The Wrong Doctors " ) , usually referred as telepathic circuits ( TV : " The Time Monster " onwards ) or telepathic induction circuits , was a TARDIS component with multiple functions . Communication . The telepathic circuits could be used to send messages telepathically to other people . The Third Doctor once used them to send the Time Lord s a message about ' s alliance with the Dalek s when both sides tried to trigger a war between Earth and Draconia . ( TV : " Frontier in Space , Planet of the Daleks " ) Idris used this function to lead Rory to an archived TARDIS control room , letting him drop the shields and allow the Junk TARDIS to enter the Doctor ' s TARDIS . ( TV : " The Doctor ' s Wife " ) It was also somehow connected to the Doctor ' s use of the TARDIS phone , and could be accessed externally by powerful beings such as the Beast . ( COMIC : " The Beast Is Back In Town " ) Translation . Additionally , this element of the TARDIS systems allowed its occupants to understand and speak languages other than their own . The TARDIS ' pilot seemed to be an integral part of the telepathic circuits ; if the Time Lord were unconscious or severely injured , the translation effect might not work correctly . ( TV : " The Christmas Invasion " ) While the Doctor ' s companions heard and spoke their native languages and did not perceive the translation effect , the Doctor himself was aware of the translation and whatever local language was being spoken . ( TV : " The Fires of Pompeii , The Girl in the Fireplace " ) Should someone benefiting from the translation effect attempt to override it and deliberately speak the local language , it came across to the locals as garbled . It also seemed the listener ( at least on Earth ) heard something similar to the language of the speaker ' s native culture in that time period . ( TV : " The Fires of Pompeii " ) The translation circuits translated writing as well as speech . ( TV : " The Fires of Pompeii " , " A Good Man Goes to War " ) They did not work on languages that the Time Lords themselves don ' t know , suggesting it acted like a translator for a vast number of languages . ( TV : " Four to Doomsday " , " The Impossible Planet " ) The translation circuits could translate all text in an area to show one specific message , as when the TARDIS translated all text on Shan Shen to " Bad Wolf " . ( TV : " Turn Left " ) Memory . Navigation . The Eleventh Doctor used the circuits to pinpoint the saddest memory in Amy ' s life . Even if the memory seemed too ridiculous to be her saddest memory , Amy was encouraged by the Doctor to replace the ice cream she lost in 1994 to make her past self happy . ( HOMEVID : " Good Night " ) The Eleventh Doctor linked Clara Oswald to the circuitry in order to retrieve from her mind the visual coordinates of Trenzalore . ( TV : " The Name of the Doctor " ) The Twelfth Doctor , trying to find out what the creature that he believed followed him was , hooked Clara up to the telepathic circuits , taking the form of a gel - like substance she could put her hands in and used them to extrapolate her timeline from birth to death . By focusing on a moment in her past , she could then effectively control the TARDIS to visit it . As Clara got distracted by a phone call from Danny Pink , she inadvertently took them into his past instead of hers . Later , the Doctor used a trace of Clara left in the circuits to try again while Clara wasn ' t there and met Orson Pink , someone from about a century into Clara ' s future trapped at the end of the universe . When the Doctor was knocked out and they seemed to be under threat , Clara tried to use the telepathic circuits to fly them to safety once more . Clara succeeded in flying the TARDIS in this manner , but it took them far into the Doctor ' s past to when the First Doctor was a boy . ( TV : " Listen " ) After the loss of Danny Pink , the Twelfth Doctor invited Clara to link again to the circuits , question about the location of her lover , in order to retrieve him . They were brought to 3W , an organisation led by . Indeed , the consciousness of Danny was trapped there , in the Nethersphere . ( TV : " Dark Water " ) Clara Oswald managed to use on her own the telephatic circuits to drive the TARDIS to a specific fixed point in time . ( COMIC : " Four Doctors " ) Grant used the telepathic circuits in conjuction with the Hazandra to help the Doctor find the other gemstones . ( COMIC : " Ghost Stories " ) Other functions and effects . In an alternate future , the circuits of a dying Doctor ' s TARDIS awakened in Clara Oswald ' s mind the memories from an aborted timeline . ( TV : " The Name of the Doctor " ) The telepathic circuits could also be used to alter minds in other ways . The Seventh Doctor used his TARDIS ' telepathic circuits to erase some of his useless memories , accidentally erasing Ace ' s memory as well . Soon after , the Doctor used the circuits to bring forth the personality of his third incarnation when he had to disarm a cobalt bomb and was uncertain of his present self ' s expertise in handling a delicate piece of machinery . ( PROSE : " " ) When the Seventh Doctor restored Ace ' s memories to her , he accidentally gave her some of Melanie Bush ' s also , allowing her to remember Paradise Towers . ( PROSE : " " ) On another occasion , the Seventh Doctor transferred his entire conscious mind into the TARDIS telepathic circuits , erasing his own memories while protecting his mind from a telepathic assault that was trying to provoke him into killing Ace . This left him an amnesiac until he made contact with the circuit again , restoring his memory while using the circuit as a " barrier " to prevent the Valeyard from attacking him again . ( PROSE : " Matrix " ) When the Eleventh Doctor became trapped outside time after he was forced to make a trip in a Type 1 TARDIS , he attempted to guide the ship back to reality by linking himself to its telepathic circuits when the conventional controls were unresponsive , but the TARDIS reacted by trying to unleash anti - time energies across the universe , only able to perceive the evil that the Doctor had witnessed in his travels despite his efforts to focus on other details . The first nine Doctors also became trapped in the rift as it created greater distortions in reality , but eventually the Eighth Doctor was able to escape and alert the Ninth , Tenth and Twelfth Doctors to what was happening . Once these three Doctors made contact with the Eleventh , they were able to help their other selves link their TARDISes ' telepathic circuits to the Type 1 ' s , convincing the Type 1 to end its efforts to destroy the universe ( COMIC : " The Lost Dimension " ) .
