You're sure they weren't talking about people on polyphasic sleep schedules?

Also, fatal familial insomnia is a thing, so we have a pretty good idea of what happens when people are deprived of sleep for too long.

FFI is a bad model for long term sleep deprivation since massive neuronal loss is also involved.

Just asking: do we know that massive neuronal loss does not occur with "normal" long term sleep deprivation?
