Rats! Humans and rodents process their mistakes
Date:10/20/2013

e activity of individual neurons in the MFC and motor cortex of the rats in both post-error and post-correct circumstances.

The scientists also gave the rats a drug that blocked activity of the MFC. What they saw in those rats compared to rats who didn't get the drug, was that the low-frequency waves did not occur in the motor cortex, neurons there did not fire coherently and the rats did not alter their subsequent behavior on the task.

Although the researchers were able to study the cognitive mechanisms in the rats in more detail than in humans, the direct parallels they saw in the neural mechanics of adaptive control were significant.

"Low-frequency oscillations facilitate synchronization among brain networks for representing and exerting adaptive control, including top-down regulation of behavior in the mammalian brain," they wrote.
