Current thinking!: The workings of the human brain is still largely a mystery. Electrodes can offer an insight but some fear a sinister intent!

IN THE 1983 film ‘Brainstorm’, Christopher Walken and Natalie Wood develop a brain-computer interface (BCI) to read and process thoughts, which are then transferred to video tape to be shared with other people. This was used to share happy memories to reconcile the estranged pair, but also to experience a fellow scientist's heart attack, and it was the target of the military interest for torture and brainwashing.
