The £15 device that stops you waking up during operations
A £15 set of electrodes could help doctors read a patient’s mind during a general anaesthetic. Not only will this ensure the patient is properly anaesthetised, but because doctors will be able to monitor the effect of the anaesthesia more accurately, this will reduce dosages, so patients will wake up less woozy, and cut the risk of overdose.

A still from the film ‘Awake’, in which the character of Clayton Beresford Jr. (played by Hayden Christensen) wakes up during a heart transplant.
