>>14108688To expand upon this, take a lesser mammal for example. Without a prefrontal cortex (or lacking in density thereof), decisions are made on a very short-term go or no-go system in which food, for example, is the reward driven by dopamine but the visible lions in the distance serve as a no-go by increasing the norepinephrine:dopamine ratio. When NE higher than baseline to a degree larger than DA vs baseline, the action is either avoided or will proceed with caution. Humans with a functional prefrontal cortex have a second go/no-go system in the PFC in which a third party system gives feedback based on prior experience and memory.
