Doctors currently have no perfectly reliable way of ensuring patients are adequately unconscious before an operation begins.
Measuring certain kinds of brain activity may help doctors track and predict how patients will react to anaesthesia before going under for surgery, our research has found.
Can a machine really think, be in awe and wonder?
As machines get ever more complex as we strive to make them complete more complex tasks, it's time to ask again: will they ever be able to think? But what is thinking anyway?
