freedom from brain scans

Sigh... I suppose this will be an ethical issue in nursing at some point, and some brainiac nursing theorist will say we should scan people's brains to extract 'total information' for 'total treatment'...

We think of our brains as the ultimate private sanctuary, a zone where other people can't intrude without our knowledge or permission. But its boundaries are gradually eroding. Hypersonic sound is just a portent of what's coming, one of a host of emerging technologies aimed at tapping into our heads. These tools raise a fascinating, and queasy, new ethical question: Do we have a right to "mental privacy"?

"We're going to be facing this question more and more, and nobody is really ready for it," says Paul Root Wolpe, a bioethicist and board member of the nonprofit Center for Cognitive Liberty and Ethics. "If the skull is not an absolute domain of privacy, there are no privacy domains left." He argues that the big personal liberty issues of the 21st century will all be in our heads — the "civil rights of the mind," he calls it.

But this isn't just about reading minds; it's also about bombarding them with messages or tweaking their chemistry. Transcranial magnetic stimulation — now used to treat epilepsy — has shown that it can artificially generate states of empathy and euphoria. And you've probably heard of propranolol, a drug that can help erase traumatic memories.

Let's say you've been assaulted and you want to take propranolol to delete the memory. The state needs that memory to prosecute the assailant. Can it prevent you from taking the drug? "To a certain extent, memories are societal properties," says Adam Kolber, a visiting professor at Princeton. "Society has always made claims on your memory, such as subpoenaing you." Or what if you use transcranial stimulation to increase your empathy. Would you be required to disclose that? Could a judge throw you off a jury? Could the Army turn you away?
