Electrodes at multiple brain regions reveal brain activity in real time. Colored dots show the locations of all of the electrodes across all patients, color-coded by brain region. Red dots in the lower images show the locations of the electrodes in the DMN.
And the neurological source of creativity—what’s going on in our brains when we think outside the box—is similarly elusive.has used a precise method of brain imaging to unveil how different parts of the brain work together in order to produce creative thought.The new results could ultimately help lead to interventions that spark creative thought or aid people who have mental illnesses that disrupt these regions of the brain.Higher cognitive processes like creativity are especially hard to study.
Participants in the study were already undergoing this kind of seizure monitoring, which meant that the research team could also use the electrodes to measure brain activity during creative thinking. This provided a much more detailed picture of the neural basis of creativity than researchers had been able to capture before. “We could see what’s happening within the first few milliseconds of attempting to perform creative thinking,” Shofty says.
The activity of the network is changed in several disorders, such as ruminative depression, in which the DMN is more active than normal, possibly related to increased dwelling on negative internally directed thoughts. Shofty says that a better understanding of how the network operates normally may lead to better treatments for people with such conditions.
