That is usually the journal article where the information was first stated. In most cases Physiopedia articles are a secondary source and so should not be used as references. Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article).

Introduction[edit | edit source]Humans have big brains and our frontal lobes, just behind the forehead, are particularly huge. The frontal lobes, the largest of the four, are in many ways the lobe which participates most in making us human (It is one of the lobes of the neocortex).
Gross Anatomy[edit | edit source]The frontal lobe is the largest lobe accounting for 41% of the total neocortical volume.

Evolution[edit | edit source]For many years, many scientists thought that the frontal lobe was comparatively larger in humans than in other primates. 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, what sets us apart from other mammals is not so much brain size but reorganization of our brains in terms of connectivity and neurotransmitter changes. These changes may be summarized in the following manner.
Brain size: The so-called “missing link” hominid, Australopithecus africanus (brain volume approximately 450 mL), 3 million years later Neanderthals approx. 1500 mL and subsequently a slight decrease again in modern humans Homo sapiens sapiens to 1350 mL[6]. Damage[edit | edit source]The frontal lobes are considered our emotional control center and home to our personality. There is no other part of the brain where lesions can cause such a wide variety of symptoms. See Frontal Lobe Injury The frontal lobes are extremely vulnerable to injury due to their location at the front of the cranium, proximity to the sphenoid wing and their large size. MRI studies have shown that the frontal area is the most common region of injury following mild to moderate traumatic brain injury
Summary[edit | edit source]The frontal lobe collects some information from the body and environment. It also gathers information from all other parts of the brain.It then sorts out what that information means; and organises a response. The frontal lobe manages most of what the brain does. It keeps us from doing really silly things and is responsible for the charming personality you have![4] References[edit | edit source]
What are the 4 lobes of the brain and their functions?The four lobes of the brain are the frontal, parietal, temporal, and occipital lobes (Figure 2). The frontal lobe is located in the forward part of the brain, extending back to a fissure known as the central sulcus . The frontal lobe is involved in reasoning, motor control, emotion, and language.
What is the 5th lobe of brain?Deep within the lateral sulcus (Sylvian fissure) is the fifth lobe of the brain, the insular lobe. This lobe is not clearly visible from the outside, but can be viewed when the temporal lobe is retracted from the cortex.
Which brain lobe is responsible for hearing language processing and memory?Separated from the frontal lobe by the lateral fissure, the temporal lobe also contains regions dedicated to processing sensory information, particularly important for hearing, recognising language, and forming memories.
Which brain lobe is responsible for voluntary movement thinking personality and intentionally or purpose?The frontal lobes are important for voluntary movement, expressive language and for managing higher level executive functions.
