An ambulatory EEG is where brain activity is recorded throughout the day and night over a period of one or more days. The electrodes will be attached to a small portable EEG recorder that can be clipped on to your clothing.
Orca (film) Orca (also known as Orca: The Killer Whale) is a 1977 American adventure horror film directed by Michael Anderson and produced by Dino De Laurentiis, starring Richard Harris, Charlotte Rampling, and Will Sampson. It is based on Arthur Herzog's novel of the same name.
Orca is Latin for a kind of whale. Because wild killer whales are not a threat to humans, and the term killer has a derogatory tone, many people now refer to these whales as orcas, rather than killer whales. At least in the U.S., and even among whale researchers, killer whale still seems to be used more commonly, although I've used both terms in this article.
