"Time to relax, rewind, and remodel the brain."
The rats succumbed to the rat race.
Robert Sapolsky, a neuroscientist who is also a first-rate writer, says, "we're lousy at recognizing when our normal coping mechanisms aren't working. Our response is usually to do it five times more, instead of thinking, maybe it's time to try something new."
But genuine hope arrives fast: "with only four weeks’ vacation in a supportive setting free of bullies and Tasers, the formerly stressed rats looked just like the controls, able to innovate, discriminate and lay off the bar." (The bar they press to get a food pellet.)
“The brain is a very resilient and plastic organ....Dendrites and synapses retract and reform, and reversible remodeling can occur throughout life.”
And too many pellets can make you fat.
