Following a frontal lobe injury, an individual's abilities to make good choices and recognize consequences are often impaired. Memory impairment is another common effect associated with frontal lobe injuries, but this effect is less documented and may or may not be the result of flawed testing. [ 3 ]
Orbital part of inferior frontal gyrus (pars orbitalis) (cortex inferior and anterior to the horizontal ramus of the lateral sulcus) Cytoarchitecturally the opercular part of the inferior frontal gyrus is known as Brodmann area 44 (BA44). The triangular part of the inferior frontal gyrus is known as Brodmann area 45 (BA45), and the orbital part ...
People with left inferior frontal lobe damage produced less facial expression and could not analyze emotional situations as well as those with right frontal lobe damage especially with fear and disgust. [n 9] The left inferior frontal gyrus (IFG) plays an important role in anger while the right IFG plays a larger role in disgust. [14]
FCMS is primarily originates from damages in the posterior region of the inferior frontal gyrus and inferior region of the precentral gyrus. [6] Anatomically, the word operculum is defined as the cortices encompassing the insula , which includes the pre and post-central, inferior-frontal, supramarginal, angular inferior parietal, and superior ...
Research shows that the most common areas to have focal lesions in non-penetrating traumatic brain injury are the orbitofrontal cortex (the lower surface of the frontal lobes) and the anterior temporal lobes, areas that are involved in social behavior, emotion regulation, olfaction, and decision-making, hence the common social/emotional and ...
Frontal lobe disorder, also frontal lobe syndrome, is an impairment of the frontal lobe of the brain due to disease or frontal lobe injury. [5] The frontal lobe plays a key role in executive functions such as motivation, planning, social behaviour, and speech production. Frontal lobe syndrome can be caused by a range of conditions including ...
The anterior superior frontal lobe is known as the prefrontal cortex which is responsible for the initiation and ideation of verbal speech. [7] The damage leaves the major language networks, Broca's and Wernicke’s areas and the arcuate fasiculus, unaffected. [1]
The tumor and the surgery destroyed the left inferior and middle frontal gyrus, the head of the caudate nucleus, the anterior limb of the internal capsule, and the anterior insula. However, there were minimal language problems three months after removal and the individual returned to his professional work.
