BA10 was originally defined broadly in terms of its cytoarchitectonic traits as they were observed in the brains of cadavers, but because modern functional imaging cannot precisely identify these boundaries, the terms anterior prefrontal cortex, rostral prefrontal cortex and frontopolar prefrontal cortex are used to refer to the area in the ...
The prefrontal cortex has been defined based on cytoarchitectonics by the presence of a cortical granular layer IV.It is not entirely clear who first used this criterion. Many of the early cytoarchitectonic researchers restricted the use of the term prefrontal to a much smaller region of cortex including the gyrus rectus and the gyrus rostralis (Campbell, 1905; G. E. Smith, 1907; Brodmann ...
SIRVA is caused by improper insertion of the needle used in injections. It is "a preventable occurrence caused by the injection of a vaccine into the shoulder capsule rather than the deltoid muscle. As a result, inflammation of the shoulder structures causes patients to experience pain, a decreased range of motion, and a decreased quality of life."
In a 2006 study, patients with left prefrontal lesions on the SFG exhibited poorer results on working memory tasks than the control group. Mapping showed the lateral and posterior portions of the SFG contributed the most to the working memory deficit (mostly in Brodmann area 8 in front of the frontal eye field ).
The ventromedial prefrontal cortex (vmPFC) is a part of the prefrontal cortex in the mammalian brain. The ventral medial prefrontal is located in the frontal lobe at the bottom of the cerebral hemispheres and is implicated in the processing of risk and fear , as it is critical in the regulation of amygdala activity in humans.

In human brain anatomy, the lateral prefrontal cortex (LPFC) is part of the prefrontal cortex (PFC). According to Striedter [ 1 ] the PFC of humans can be delineated into two functionally, morphologically, and evolutionarily different regions: the ventromedial PFC (vmPFC) present in all mammals and the LPFC present only in primates .
[1] [2] [3] There are also specific functional differences in activity in the right and left VLPFC. [4] Neuroimaging studies employing various cognitive tasks have shown that the right VLPFC region is a critical substrate of control. [4] At present, two prominent theories feature the right VLPFC as a key functional region.
The dorsolateral prefrontal cortex (DLPFC or DL-PFC) is an area in the prefrontal cortex of the primate brain. It is one of the most recently derived parts of the human brain. It undergoes a prolonged period of maturation which lasts into adulthood. [1] The DLPFC is not an anatomical structure, but rather a functional one.
