Learn Something New

Learn Something New

Learn something new - your brain will thank you

Gary Marcus. CNN

The idea that learning a new skill - say juggling, cooking, or playing guitar - can be like an addiction is no joke.

I should know. As a college professor/scientist, who has written about the dynamics of narcotics and self-control, I have spent the last 3 1/2 years all but addicted to learning to play guitar. Despite lacking anything that might remotely resemble musical talent, I find no day is complete without at least a little bit of time on the guitar.

Even listening to music can be a little like a drug. A brain imaging study that came out last year proved what many scientists long suspected: Listening to music can lead the brain to release the neurotransmitter dopamine. Dopamine is the brain's universal signal for pleasure, an internal system that tells the brain (sometimes rightly, sometime wrongly) that it is doing the right thing.

Drugs elicit dopamine artificially by fooling the brain, while activities like sex and eating elicit dopamine naturally. Listening to music taps into the dopamine system in part because hearing something new is a signal that the brain is learning something, and we have evolved to enjoy acquiring new information.

Shortcuts like drugs, however are fleeting. Although narcotics can elicit dopamine fairly directly, over time it takes a bigger and bigger dose to get the same rush, and can lead people to destroy families, risk their health and even lose their lives.

Learning new things is a lot safer, and ultimately a lot more satisfying.
