Study of the Frontal Lobe
The frontal lobe composes of cortices divided into Brodmann areas that are numbered as areas 4, 6, 8, 10-14, 24-32 and 454-49. Among them, the dorsolateral prefrontal cortex occupies Brodmann area 46-49 while the ventromedial prefrontal cortex covers a series of Brodmann areas such as 10, 14, 25 and 32. The other cortices are the primary motor cortex (B.A. 4), Premotor cortex (B.A. 6), the cingulate cortex (B.A 24-32) and the orbitofrontal cortex (B.A 10-14). The most massive cortex among those in the frontal lobe is the dorsolateral prefrontal cortex. It is positioned superior to the orbitofrontal cortex.
The dorsolateral prefrontal cortex is the largest that involves multiple sensory modalities. It enables the body to utilize inputs from the visual and auditory pathways, including other neuro-sensory functions. It also has a cognitive function, since it is the “working memory,” where it generates complex cognition. When the area is damaged, the patient presents with five main symptoms. They include the patients depicting poor recall and the inability to organize learning, where the patient, in that case, has a wrong sequence of ideas that have been recently learned. Also, there is difficulty in integrating the sensory information provided, where the patient is unable to reconstruct a dismantled structure (Seminowicz & Moayedi, 2017). There is also the difficulty in generating t…
