Read about the lab's Nature Reviews Neuroscience paper in the Wall Street Journal!
Here is an excerpt from the piece:
"Other brain areas constrain and modify mind-wandering—such as parts of our prefrontal cortex, the control center of the brain. In my case, this control system may try to pull my attention back to external goals like writing my column. Or it may shape my wandering mind toward internal goals like planning what I’ll make for dinner.
Dr. Christoff and colleagues suggest that creative thought involves a special interaction between these control systems and mind-wandering." - Alison Gopnik
