Wirehead (science fiction)
Wirehead is a term used in science fiction works to denote different kinds of interaction between people and technology.
Known Space stories
In Larry Niven's Known Space stories, a wirehead is someone who has been fitted with an electronic brain implant (called a "droud" in the stories) to stimulate the pleasure centres of their brain. In the Known Space universe, wireheading is the most addictive habit known (Louis Wu is the only given example of a recovered addict), and wireheads usually die from neglecting themselves in favour of the ceaseless pleasure. Wireheading is so powerful and easy that it becomes an evolutionary pressure, selecting against that portion of Known Space humanity without self-control. Wireheading need not use an actual brain implant; the pleasure centre can be remotely activated by a small device called a "tasp" (important in the Ringworld novels).
A wirehead's death is central to Niven's Gil 'the Arm' Hamilton story, Death by Ecstasy, published by Galaxy Magazine in 1969, and a main character in the book Ringworld Engineers is a former wirehead trying to quit.
Niven's stories explain wireheads by mentioning a study in which experimental rats had electrodes implanted at strategic locations in their brains, so that an applied current would induce a pleasant feeling. If the current could be obtained anytime the rats pushed the lever, they would use it over and over, ignoring food and physical necessities until they died. Such experiments were actually conducted by James Olds and Peter Milner in the 1950s, first discovering the locations of such areas, and later showing extremes to which rats would go to obtain the stimulus again.
The Centurions (animated series)
In episode 41, "Zone Dancer" of The Centurions (TV series) animated series, the lead character Crystal Kane is accused of "Zone Dancing" (The series term for computer hacking) and seen using a "droud" to interface her brain with computer networks in what is probably the first animated representation of Cyberspace and Virtual Reality. The story written by Michael Reaves weaves a future noir tale of cyberpunk espionage, cloning and private-eye procedural, all set in the universe of the animated series and makes copious references to William Gibson's Neuromancer story. There is even a Zone Dancer named Gibson and what may be an homage to Larry Niven's Louis Wu there is even a cyberneticst named Dr. Wu.
- Mindkiller, a sci-fi novel by Spider Robinson. Mindkiller is a 1982 novel by science fiction writer Spider Robinson. The novel, set in the late 1980s, explores the social implications of technologies to manipulate the brain, beginning with wireheading, the use of electrical current to stimulate the pleasure center of the brain in order to achieve a narcotic high.
