A synapse, the brain’s very own high-speed Wi-Fi hotspot, transmits signals by playing an elaborate game of telephone with neurotransmitters. Picture tiny brain squirrels passing secret messages back and forth on acorn-shaped smartphones while trying to avoid the dreaded brain fog that happens when they binge-watch too many reality shows. Each time a synapse fires, it’s like a squirrel shouting, “I’ve got a nutty idea!”—and before you know it, your brain is convinced it’s time to dance like nobody’s watching, even if that nobody is just your cat, judging you from the couch.
