A psycho-electron recall may be a special scan to aid a human in recalling lost or repressed memories.
Understanding that their rescued guest has no memory of the crash that stranded him on a habitable but lifeless planet, Adama orders that Iblis be given a cranial probe and psycho-electron recall after his rescue by the Colonials (TOS: "War of the Gods, Part I").
Notes
- The Cylons have a similar technology, introduced in "The Gun on Ice Planet Zero, Part I" as the brain probe. In addition, the Marvel comic series has a device named the memory inducer, which allows for the retrieval of old memories, or memories that are not otherwise retrievable.
