This is Hidden Brain.
I'm Shankar Vedantam.
Across centuries, artists and writers have tried to make sense of the mysterious force that brings ideas to life.
The ancient Greeks imagined the muse as a literal spirit,
a whispering goddess who breathed inspiration into the poet's ear.
Renaissance painters courted her through ritual and prayer,
while romantic poets looked for her in storms, mountain peaks, and moonlit walks.
Now, psychological research is discovering that what the ancients call divine inspiration is really the brain at play.
When we are relaxed, taking a shower, folding laundry,
staring out a window, our minds slip into a pattern of spontaneous association.
Neurons fire across disparate brain regions, linking old memories with half-formed ideas.
Then, suddenly, an insight bubbles up.
It feels like a gift from the heavens, but it's really the product of our own unconscious minds.
This week on Hidden Brain and in a companion story on Hidden Brain Plus,
the origins of creativity and how to find the muse within.
