Zapping the brain with magnetic pulses while measuring its electrical
activity is proving to be a reliable way to detect consciousness

Even with access to brain-imaging tools, a physician can have difficulty
establishing whether a severely brain-injured patient is conscious of his or
her surroundings.

A technology to address this gap in care would, in principle, determine
whether a patient is deeply asleep or anesthetized or has lost consciousness
because of damage to the brain.

Over the past few years development of what might be called "consciousness
meters" opens the possibility of reliable detection devices that can be used
in medical settings.

Physicians and family members might use such technologies to help them make
decisions about care for the tens of thousands of patients unable to
communicate their needs.
