Syncope is the temporary loss of consciousness due to a sudden decline in blood flow to the brain. It may be caused by an irregular cardiac rate or rhythm or by changes of blood volume or distribution. Syncope can occur in otherwise healthy people. The patient feels faint, dizzy, or lightheaded (presyncope), or loses consciousness (syncope).

In the anatomy of animals, the brain, or encephalon, is the supervisory center of the nervous system. Although the brain is usually cited as the supervisory center of vertebrate nervous systems, the same term can also be used for the invertebrate central nervous system. In most animals, the brain is located in the head.
