he and his colleagues rounded up 19 volunteers and asked them to review more than 100 trivia questions. Questions such as, “What does the term ‘dinosaur’ actually mean?” and “What Beatles single lasted longest on the charts, at 19 weeks?”
Participants rated each question in terms of how curious they were about the answer.
Next, everyone reviewed the questions — and their answers — while the researchers monitored their brain activity using an MRI machine. When the participants’ curiosity was piqued, the parts of their brains that regulate pleasure and reward lit up. Curious minds also showed increased activity in the hippocampus, which is involved in the creation of memories.
“There’s this basic circuit in the brain that energizes people to go out and get things that are intrinsically rewarding,” Ranganath explains. This circuit lights up when we get money, or candy. It also lights up when we’re curious.
When the circuit is activated, our brains release a chemical called dopamine which gives us a high. “The dopamine also seems to play a role in enhancing the connections between cells that are involved in learning.”
Indeed, when the researchers later tested participants on what they learned, those who were more curious were more likely to remember the right answers.
