[Criteria of brain death]

Area of Science:

• Neurology
• Medical Ethics

Background:

• Previous work criticized the ambiguous term "passed coma" in favor of "brain death".
• The term "brain death" is not entirely accurate as the brain stem, or medulla, is the critical area responsible for death.

Purpose of the Study:

• To refine the terminology surrounding brain death.
• To discuss diagnostic tests for the brain stem's function in determining death.

Main Methods:

• Review of existing terminology and concepts.
• Discussion of neurophysiological tests targeting the brain stem.

Main Results:

• The medulla oblongata is identified as the primary site responsible for death.
• Exploratory tests for brain stem function are considered.

Conclusions:

• The term "brain death" requires further precision, focusing on the brain stem.
• Further investigation into brain stem specific diagnostic tests is warranted.
