Rats! Humans and rodents face their errors

Evidence of error

Low-frequency brainwaves in the human medial frontal cortex change from low-power (blue) to high-power (red-orange) at the recognition of a mistake.

What happens when the brain recognizes an error? A new study shows that the brains of humans and rats adapt in a similar way to errors by using low-frequency brainwaves in the medial frontal cortex to synchronize neurons in the motor cortex. The finding could be important in studies of “adaptive control” problems like obsessive compulsive disorder, ADHD, and Parkinson’s.
