What is Frontal lobe?

It is in front of the [[parietal lobe]] and above and in front of the [[temporal lobe]]s. The frontal lobes takes action based on sensory information ([[sight]], [[sound]], [[touch]]) from the three rear areas of the [[cerebrum]]. The action is moderated by the influence of the [[pre-frontal cortex]]. The system is a delicate balance between the need to satisfy urges from the most ancient parts of the brain, such as [[hunger]], self-defence and sex, with the need to act in a way which is socially acceptable. The [[precentral gyrus]], forming the back of the frontal lobe, contains the [[primary motor cortex]]. This controls [[wikt:voluntary|voluntary]] movements of specific body parts. ==Evolution== For many years, many scientists thought that the frontal lobe was comparatively larger in humans than in other [[primate]]s. They thought that this was an important feature of [[human evolution]] and was the main reason why human [[cognition]] is different from that of the other primates. However, this view has been challenged by later research. [[Magnetic resonance imaging]] was used to find the [[volume]] of the frontal cortex in humans, all living [[ape]] species and several [[monkey]] species. The human frontal cortex is ''not'' relatively larger than the cortex in the other [[Hominidae|great ape]]s, but it is relatively larger than the frontal cortex in the [[Gibbon|lesser ape]]s and the
