Alan Turing was a hero. He was a mathematician who played a key role in the development of computer science and artificial intelligence and, during World War II, he led Britain’s German code-breaking team, cracking secret messages that gave the Allies an edge in critical battles against the Nazis.
Turing was also a homosexual. In 1952 he was prosecuted for having a sexual relationship with another man, a crime at that time in the United Kingdom. In order to avoid prison, Turing underwent chemical castration: Injections of a drug that took away his libido, while also causing him to have enlarged breasts. His death two years later from cyanide poisoning was ruled a suicide.
The Turing tragedy is just one of many examples of a legal neuro-intervention: The use of a drug or other medical means to change someone’s behavior – sometimes permanently. Despite a problematic past record, a range of such interventions are poised to expand within the legal system and could even become routine.
The conference Neruo-Interventions and the Law: Regulating Human Mental Capacity will gather leading legal scholars, judges, ethicists, neuroscientists and psychologists at Georgia State University September 12-14 to grapple with some of the thorny legal issues being spurred by advances in neuroscience. Registration is free, but there is limited seating.

The case of British computer scientist Alan Turing, who submitted to chemical castration in 1952 to avoid imprisonment for homosexuality, exemplifies why a judicial system should take the long view before resorting to drugs to alter a person's behavior and biology. Benedict Cumberbath, above, portrays Turing in the upcoming movie "The Imitation Game."
