A single test, such as the WCST, cannot be used to measure the effects of a frontal lobe injury, or the aspects of cognitive function it may affect, such as working memory; variety of tests must be used. A subject may be good at one task but show dysfunction in executive function overall. Similarly, test results can be made misleading after ...
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 ...
Broca's area, or the Broca area (/ ˈ b r oʊ k ə /, [1] [2] [3] also UK: / ˈ b r ɒ k ə /, US: / ˈ b r oʊ k ɑː / [4]), is a region in the frontal lobe of the dominant hemisphere, usually the left, of the brain [5] with functions linked to speech production.
Brodmann area 44, or BA44, is part of the frontal cortex in the human brain.Situated just anterior to premotor cortex and on the lateral surface, inferior to BA9.. This area is also known as pars opercularis (of the inferior frontal gyrus), and it refers to a subdivision of the cytoarchitecturally defined frontal region of cerebral cortex.
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 ...
From this perspective, the right lateral PFC, along with a region spanning the right temporoparietal junction (TPJ) and the inferior parietal lobule, are engaged when abrupt onsets occur in the environment, suggesting that these regions are involved in re-orienting attention to perceptual events that occur outside the current focus of attention ...
In the human, on the orbital surface it surrounds the caudal portion of the orbital sulcus (H) from which it extends laterally into the orbital part of inferior frontal gyrus (H). Cytoarchitectonically it is bounded caudally by the triangular area 45 , medially by the prefrontal area 11 of Brodmann-1909, and rostrally by the frontopolar area 10 ...
