		+	The '''Prefrontal Cortex''' (PFC) is the very front of the brain, located right beneath the forehead. It is in the anterior (front) region of the frontal lobes. The PFC is believed to have the most activity in a human, mainly because it contains the behavior of executive functions, which include mediating conflicting thoughts, making choices between right and wrong or good and bad, predicting future events, and governing social control -- such as suppressing emotional or sexual urges.
		+
		+	'''Areas'''
		+
		+	- lateral prefrontal cortex seems to help us choose a course of behavior by letting us evaluate the various alternatives mentally.
		+
		+	- orbitofrontal cortex seems to let us reschedule certain immediate pleasure and contain certain emotions in order to obtain greater long-term benefits.
		+
		+	-ventromedial cortex is thought to be one of the sites in the brain where we experience emotions and the meanings of things.
