The Roles of the Four Lobes of the Cerebral Cortex
The cerebral cortex is divided into four lobes; the temporal, occipital, parietal, and frontal (Myers, 2011). These lobes are responsible for various functions that range from auditory perception to reasoning. This paper discusses the roles of the cerebral cortex’s four lobes.
The frontal lobe
This lobe is based at the brain’s front. It is linked to expressive language, higher level cognition, motor skills, and reasoning. The motor cortex that receives information from the other lobes uses it to perform body movements is located in this lobe. Its damage leads to changes in socialization, attention, sexual habits, and increased risk- taking.
Parietal lobe
This lobe is located in the brain’s middle section. It mainly deals with the procession of tactile sensory information that includes pain, touch, and pressure. The somatosensory cortex is based in this lobe and it helps in processing the body’s senses. Therefore, damage of the parietal lobe exposes an individual to verbal memory, language problems, and difficulty controlling the eye gaze (Myers, 2011).
Occipital lobe
The occipital lobe forms the brain’s back portion. Its cardinal role is interpreting information and visual stimuli. The lobe also hosts the primary visual cortex whose role is receiving and interpreting information from the eyes’ retina. Therefore, damage of this lobe leads to visual challenges including the inability to distinguish colors and trouble or difficulty recognizing words and objects (Myers, 2011).
Temporal lobe
This lobe constitutes the brain’s bottom section. The primary auditory cortex is also located in this lobe, which is important in interpreting the language and sounds people hear (Myers, 2011). The hippocampus’s location is also in this lobe, which explains why this brain portion is hugely linked to memories’ formation. If the temporal lobe is damaged, a person experiences challenges involving language skills, speech perception, and memory. In essence, the functions of the four cerebral cortex’s lobes are vital for the proper functioning of an individual.
