The article indicates it's the actual scan and says the space "was filled with cerebrospinal fluid, which cushions the brain and provides defence against disease."
Don't read the article provided too carefully. The image isn't a CT and has been dumbed down from the source. The image is an MR not a CT, and the image below is some sort of made up composite image. Original source with proper images: http://brain.oxfordjournals.org/content/early/2014/08/22/bra...
