Eyes Wide Shut: How Newborn Mammals Dream the World They’re Entering

Effectively, mammals "dream" about the world they are about to experience before they are able to open their eyes and possibly before they are born. Researchers found before a newborn mouse opened its eyes, its retinal waves flow in a pattern that mimics the activity which would occur as the animal moves through the environment.

A New Theory for What’s Happening In the Brain When Something Looks Familiar

Researchers propose a new theory of what happens in the brain when we experience familiar seeming visual stimuli. The theory, dubbed sensory referenced suppression, suggests the brain understands different levels of activation expected for sensory input and corrects for it, leaving behind the signal for familiarity.
