Brain-rack

The brain-rack was an interrogation tool designed by the Ice Warriors specifically for use on humans. It created artificial neural pathways in the human mind which dominated the existing thought processes and ultimately ensured obedience in the subject. Brain-racks were said to have no harmful side effects and the process wore off after a week or so when the artificial engrammes began to decay and the natural pathways reasserted themselves. Seen as a potential brainwashing tool, the brain-rack also increasing learning rates by three hundred percent. (PROSE: GodEngine)
