One of the big theories going on in Neuroscience right now is Dual Systems Model. Basically, it theorizes that cognition matures in the mid-teens, but the limbic system is immature until the mid-twenties.
This is a scatter plot that supposedly shows proof of that. The researchers however, drew an upwards curve that the data didn't reflect (outside of 2 big outliers). Instead, the data implies around the mid-teens onwards, the limbic system in the prefrontal cortex is mature.
So, if the limbic system isn't immature going off by their own data, how did they draw these conclusions?
