You searched for: “neurobics
A term for mental exercises which are used to increase the range of mental motion by activating different parts of the brain.

Apparently coined in imitation of the word aerobics by Dr Lawrence C Katz and Manning Rubin in their 1999 book Keep Your Brain Alive to present mental exercises invented to help people keep their brains "alive". Remaining mentally active, it’s advocated, keeps the links between brain cells alive and busy.

There are those who insist that we cannot separate the mind’s software from its hardware and that the true aim of neurobics is to keep the connections between brain cells flexible and strong, perhaps even growing new connections and new brain cells.
