Brief Summary:
This study examines muscle movements of elecromyography in adults with brain death. Half of the participants will have brain death, the other half will be healthy volunteers.

Condition or disease
Brain Death

Detailed Description:
In some of the patients who have brain death diagnosis, some movements may be seen. Because of these movements, the doctors sometimes avoid to make brain death diagnosis. So making brain death diagnosis may delay. And in these patients, even if the brain death diagnosis made the family members refuse to donate the organs of the patients because they think their patients may survive when they see muscle movements with touch. These patients with brain death are lost in a short time, so some of the patients can not be used as donors. In this study, the investigators aim to raise awareness the movements in brain death patients can be seen, to study the movements neurophysiologically by EMG, whether EMG can be used as auxiliary method or not in brain death diagnosis and to raise organ donation numbers from cadavers. Investigators will examine the motor response and F response in the facial nerve, median nerve, and tibialis posterior nerve with electromyography neurophysiologically.
