이 ROI와 관련되어서 많이 이야기가 되는 것이 브로드만 영역입니다.
그래서 우리가 신경해부학을 배울 때 각각의 cerebral cortex가 어떠한 브로드만 영역에 매칭이 되는가를 아는 것이 꽤 중요합니다.
브로드만이 처음으로 이 영역을 정의한 것이 1909년이니 벌써 100여년 전의 이야깁니다. (Brodmann areas were originally defined and numbered by the German anatomist Korbinian Brodmann based on the cytoarchitecturalorganization of neurons he observed in the cerebral cortex using the Nissl stain. Brodmann published his maps of cortical areas in humans, monkeys, and other species in 1909,)
최근에 위키피디아(http://en.wikipedia.org/wiki/Brodmann_area)에서 업데이트가 되면서 이 부분이 첨가가 되었습니다.
Brodmann areas for human & non-human primates[edit]
- Areas 3, 1 & 2 – Primary Somatosensory Cortex (frequently referred to as Areas 3, 1, 2 by convention)
- Area 6 – Premotor cortex and Supplementary Motor Cortex (Secondary Motor Cortex)(Supplementary motor area)
- Area 8 – Includes Frontal eye fields
- Area 10 – Anterior prefrontal cortex (most rostral part of superior and middle frontal gyri)
- Area 11 – Orbitofrontal area (orbital and rectus gyri, plus part of the rostral part of the superior frontal gyrus)
- Area 12 – Orbitofrontal area (used to be part of BA11, refers to the area between the superior frontal gyrus and the inferior rostral sulcus)
- Area 13 and Area 14* – Insular cortex
- Area 15* – Anterior Temporal Lobe
- Area 22 – Superior temporal gyrus, of which the caudal part is usually considered to contain the Wernicke's area
- Area 23 – Ventral posterior cingulate cortex
- Area 24 – Ventral anterior cingulate cortex.
- Area 25 – Subgenual area (part of the Ventromedial prefrontal cortex) (subgenual cingulate cortex)
- Area 26 – Ectosplenial portion of the retrosplenial region of the cerebral cortex
- Area 28 – Ventral entorhinal cortex
- Area 29 – Retrosplenial cingulate cortex
- Area 30 – Part of cingulate cortex
- Area 31 – Dorsal Posterior cingulate cortex
- Area 32 – Dorsal anterior cingulate cortex
- Area 33 – Part of anterior cingulate cortex
- Area 34 – Dorsal entorhinal cortex (on the Parahippocampal gyrus)
- Area 35 – Perirhinal cortex (in the rhinal sulcus)
- Area 36 – Ectorhinal area, now part of the perirhinal cortex (in the rhinal sulcus)
- Area 38 – Temporopolar area (most rostral part of the superior and middle temporal gyri)
- Area 39 – Angular gyrus, considered by some to be part of Wernicke's area
- Area 40 – Supramarginal gyrus considered by some to be part of Wernicke's area
- Area 43 – Primary gustatory cortex
- Area 44 – Pars opercularis, part of the inferior frontal gyrus and part of Broca's area
- Area 45 – Pars triangularis, part of the inferior frontal gyrus and part of Broca's area (also ventrolateral prefrontal cortex)
- Area 47 – Pars orbitalis, part of the inferior frontal gyrus (also ventrolateral prefrontal cortex)
- Area 48 – Retrosubicular area (a small part of the medial surface of the temporal lobe)
- Area 49 – Parasubicular area in a rodent
- Area 52 – Parainsular area (at the junction of the temporal lobe and the insula)
(*) Area only found in non-human primates.
Some of the original Brodmann areas have been subdivided further, e.g., "23a" and "23b".
위키피디아에 들어가시면 보실 수 있는 정보 중의 일부를 옮겨 왔습니다.
제가 이전에 공부할 때 직접 손으로 라벨링한 그림은 아래에 있습니다.
우리가 neuroimaging을 공부할 때에 항상 체크를 하게 되는 frontal lobe의 해부학에 대해서 겸사겸사 올려 보도록 하겠습니다.
여기에 해당되는 영역으로는 다음의 부분들이 있습니다.
- Lateral part: Precentral gyrus, lateral part of the superior frontal gyrus, middle frontal gyrus, inferior frontal gyrus.
- Polar part: Transverse frontopolar gyri, frontomarginal gyrus.
- Orbital part: Lateral orbital gyrus, anterior orbital gyrus, posterior orbital gyrus, medial orbital gyrus, gyrus rectus.
- Medial part: Medial part of the superior frontal gyrus, cingulate gyrus.
이 각각의 영역들의 의미에 대해서 다시 좀 더 자세히 알아보도록 하겠습니다.
