Which region of the brain appears to have the oldest evolutionary history?

Question

Quizplus · Accepted Answer

The brainstem is considered the oldest region of the brain, as it is responsible for basic life-sustaining functions such as breathing and heart rate. It evolved before the more advanced regions, such as the frontal lobes, which are responsible for higher cognitive functions such as decision-making and problem-solving. The limbic system, which is involved in emotion and memory, also evolved later than the brainstem. The corpus callosum is a structure that connects the left and right hemispheres of the brain and does not have an evolutionary history on its own.
