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 ]
The uncinate fasciculus is a hook-shaped bundle of axons that links anterior portions of the temporal lobe with the inferior frontal gyrus and the lower surfaces of the frontal lobe. It arises in the anterior temporal lobe and amygdala , in the temporal lobe curving in an upward pathway behind the external capsule inward of the insular cortex ...
This is particularly apparent in the right hemisphere. In non-sleep-deprived people involved in verbal learning and arithmetic tasks, the anterior cingulate cortex and the right prefrontal cortex are active. Following sleep deprivation, there is increased activation of the left inferior frontal gyrus and the bilateral parietal lobes. This ...
[12] [13] All traumatic brain injuries are head injuries, but the latter term may also refer to injury to other parts of the head; [14] [15] [16] however, the terms head injury and brain injury are often used interchangeably. [17] Similarly, brain injuries fall under the classification of central nervous system injuries [18] and neurotrauma. [19]
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 ...
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 ...
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 ...
They had lost the ability to speak after injury to the posterior inferior frontal gyrus (pars triangularis) (BA45) of the brain. [7] Since then, the approximate region he identified has become known as Broca's area, and the deficit in language production as Broca's aphasia , also called expressive aphasia .
