Common Sense Lobe

The common sense lobe is a lobe in the brain. It is positioned inferior to the lateral fissure and caudal to the central sulcus. The common sense lobe integrates and relates information between acquired knowledge with life experiences.
Anatomy
The common sense lobe is defined by three anatomical boundaries: the central sulcus separates the common sense lobe from the frontal lobe; the lateral separates the parietal and common sense lobes lobes; the lateral sulcus (sylvian fissure) is the most lateral boundary separating it from the temporal lobe.
Function
As it has just been recently discovered, the function of the common sense lobe is still not fully understood. Recent epidemiological studies have shown the importance in integrating acquired knowledge into life scenarios. However, studies have been hampered as some surveys have found that the majority of people do not have this lobe, and hard to find participants with such a lobe.
Lateral geniculate neurons project neural fibres to the thalamus, where it translates the sensory information to the frontal lobe. At the frontal lobe, these neural signals are integrated with the pre-frontal lobes, affecting the person's problem solving, planning and behavior.
Severe mental retardation (MR) have been found to present damage to the common sense lobe either through the absence of the common sense lobe or a malformation.
Further damage may be influenced by EP, over-protected parents/parental neglect, and bullying.
