Sleeping with half your brain

We all know people who seem to function with half a brain. The phrase, “what the heck were they thinking,” often comes to mind when discussing their lot. However, when they slumber, they are very similar to the rest of us. Sleep is a time for the brain to rest…in its entirety.

That is, unless you are a seal….

In a new study published in the Journal of Neuroscience , a team of scientists from the University of Toronto found that seals sleep with half their brain at a time. At least when they are in the water. On land, seals’ brains are fully at rest, much like thier human counterparts.

Want to learn more? Read how seals sleep with only half their brain at a time.

In the video below you can see how the seal needs to be half-awake in order to prevent itself from drowning in a pool of shallow water.
