Corporelectroscopy
Corporelectroscopy was the process by which two (or more) people switched their minds into each others' bodies. It could also allow one mind to take over another completely, enabling one brain to move into another individual's body, effectively taking control and killing the other.
The Javaman, a scientist with considerable imagination, called corporelectroscopy a "scientific implausibility". He was unaware that the theta-waves emitted by his Dorganator had caused the process to occur with the Sixth Doctor and Peri Brown. The Doctor later told Peri that corporelectroscopy was dangerous knowledge and that it was "best left to the Time Lords". (PROSE: Turnabout is Fair Play)
The Great Architect Kroagnon "discovered a means of performing" corporelectroscopy to transplant his brain into the Chief Caretaker of Paradise Towers. This brought about physical changes in the Chief; while Kroagnon now had a body, he walked stiffly, spoke as though his tongue was swollen, his skin took on a silvery colour, and his moustache grew.

The Cult of the Heretic forced two incarnations of the Master to switch bodies, as part of their plan to destroy the universe. The two Masters later used telepathic contact to return to their correct bodies. (AUDIO: The Two Masters)
