  2. Inferior frontal gyrus - Wikipedia

    en.wikipedia.org/wiki/Inferior_frontal_gyrus

    It was supported that phonology activated the pars opercularis (BA44), and anterior angular gyrus, multiplication mainly implicated the pars triangularis (BA45), and the posterior angular gyrus. These systems are activated through similar neuronal processes but independently placed along the network. [citation needed]

  3. Brodmann area 44 - Wikipedia

    en.wikipedia.org/wiki/Brodmann_area_44

    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.

  4. Orbital part of inferior frontal gyrus - Wikipedia

    en.wikipedia.org/wiki/Orbital_part_of_inferior...

    The orbital part of inferior frontal gyrus also known as the pars orbitalis is the orbital part of the inferior frontal gyrus. [1]In humans, this region is bordered by the triangular part of the inferior frontal gyrus (pars triangularis) and, surrounding the anterior horizontal limb of the lateral sulcus, a portion of the opercular part of inferior frontal gyrus (pars opercularis).

  5. Broca's area - Wikipedia

    en.wikipedia.org/wiki/Broca's_area

    Broca's area is now typically defined in terms of the pars opercularis and pars triangularis of the inferior frontal gyrus, represented in Brodmann's cytoarchitectonic map as Brodmann area 44 and Brodmann area 45 of the dominant hemisphere. [7]

  6. Brodmann area 45 - Wikipedia

    en.wikipedia.org/wiki/Brodmann_area_45

    Brodmann area 45 (BA45), is part of the frontal cortex in the human brain.It is situated on the lateral surface, inferior to BA9 and adjacent to BA46.. This area in humans occupies the triangular part of inferior frontal gyrus (H) and, surrounding the anterior horizontal limb of the lateral sulcus (H), a portion of the orbital part of the inferior frontal gyrus (H).

  7. Gyrus - Wikipedia

    en.wikipedia.org/wiki/Gyrus

    Inferior frontal gyrus, lat. gyrus frontalis inferior with 3 parts: pars opercularis (Brodmann area 44) pars triangularis (Brodmann area 45), and pars orbitalis (orbital part of inferior frontal gyrus) Superior temporal gyrus, lat. gyrus temporalis superior; Middle temporal gyrus, lat. gyrus temporalis medius

  8. Orbital gyri - Wikipedia

    en.wikipedia.org/wiki/Orbital_gyri

    The inferior or orbital surface of the frontal lobe is concave, and rests on the orbital plate of the frontal bone.It is divided into four orbital gyri by a well-marked H-shaped orbital sulcus.

  9. Brodmann area 47 - Wikipedia

    en.wikipedia.org/wiki/Brodmann_area_47

    Pars orbitalis is not based on cytoarchitectonic distinctions, and rather is defined according to gross anatomical landmarks. Despite a clear distinction, these two terms are often used liberally in peer-reviewed research journals. BA47 is also known as orbital area 47.
