During Sleep, the Brain switches into cleanup mode. A 2013 study found that brain cells shrink during sleep, widening the space between them by about 60%, so Cerebrospinal fluid can wash away toxic proteins such as Alzheimer's-linked beta-amyloid 10–20 times faster than when awake.

The brain of a cephalopod is shaped like a donut, with the esophagus running straight through the center. Even in a 300 kg colossal squid, the esophagus is only about 10 mm in diameter—so swallowing too large a piece of food can compress the brain and cause damage.

An octopus has roughly 500 million neurons, and more than two-thirds of them are distributed across its eight arms rather than its central brain. The brain issues high-level commands while each arm independently handles the details—a decentralized nervous system.
