I just read the abstract. Does he address the objection that nocturnal animals sleep in the day, and length of sleep doesn't change as much as the length of day over the seasons?
- JumpCrisscross 6y agoIf your eyes are closed, does it matter if it’s daytime?
- jessriedel 6y agoOh maybe I misinterpreted. I thought the author was arguing that the purpose of sleep was this protection of the visual cortex, but maybe the idea is that sleep has another purpose (with varying timing thoughout the day depending on the animal) and the purpose of dreams is to protect the visual cortex while this is going on.
