※ 引述《metalmayday (小孩子)》之铭言:
: 神经科学共笔第二十一本第十四页与第十六页内容有些矛盾
: 杏仁核传出纤维的两个路径
: stria terminalis ---> from cells of corticomedial group
: vetral amygdalofugal pathway ---> from the basolateral cell group
: (根据Haines p.508)
: 第十四页杏仁核结构第三点的B的传出纤维是否需要更改
在这边先附上课文内容:
一、临床神经解剖学基础:
杏仁核的输出:
1.主要为ventral amygdaloid path ,这些输出於前穿通质行走,并为基底核(basal
nucleus)下丘脑(Hypothalamus)及丘脑内背侧核( medial dorsal thalamic nucleus)提
供输入。内背侧核透过丘脑额前放射(thalamoprefrontal radiation)与额前皮质之间密
集的相互连接。基底外侧杏仁体与额前皮质之间的密切连结也是直接经由那连结颞叶前部
与额叶眼额部(orbitofrontal cortex)之间的连结束即钩束(uncinate fasciculus)所形
成的。
2.从中央核到前下丘脑与隔区的连结是透过那位於尾核内侧的小束纤维即”终纹”
(terminal stria )而发生。
3.左右杏仁体是经”前交连”来相互连接
二、Haines
Efferent
1.The stria terminalis is a small bundle that arises from cells of
corticomedial group.
Through most of its course, this bundle lies in the groove between the
caudate nucleus and the dorsal thalamus, where it is accompanied by the
terminal vein.
It is associated along its length with discontinuous aggregations of
cells,which collectively are called the bed nucleus of the stria terminalis
this tract distributes to various nuclei of
hypothalamus(preoptic,ventromedial,anterior,lateral), nucleus accumbens,
septal nuclei, rostral areas of the caudate nucleus and putamen.
终纹从杏仁核的皮质内侧核群发出,投射到下丘脑(视前核、前核、腹内侧、外侧)
积核(但是教官PPT P50写积核从杏仁核的输入为ventral amygdalofugal pathway >_<)
、隔核、尾核及被壳
2.the ventral amygdalofugal path. Is the major efferent fiber…
These fibers arises from the basolateral cell group and the central nucleus
of the corticomedial cell group..axons primary from basolateral cells pass
medially through the substantia innominata ,to eventually synapse in the
hypothalamus and septal nuclei. the substantia innominata gives rise to a
diffuse cholinergic projection to the cerebral cortex.
所以ventral amygdalofugal 会从皮质内侧的中央核群及基底外侧核群发出,
其中,主要从基底外侧核发出的轴突->无名质,下丘脑,中隔核…
In addition, cells of basolateral group also project diffusely to frontal and
prefrontal ,cingulate, and insular and inferior temporal cortices
基底外侧核也会投射到额叶、前额皮质、扣带回、脑岛、下颞皮质.
Other fibers, mainly from the central nucleus, turn caudally and descend
diffusely in the brainstem to terminate in visceral (dorsal motor
vagal)nuclei, raphe nucleus(magnus , obscures,pallidus), and other areas such
as the locus cereleus ,parabrachial and periaqueductal gray.
其他从中央核群发出的还会到往下投射到visceral、raphe nucleus、蓝斑
、parabrachial and periaqueductal gray
以上是我从haines.临床神经解剖学基础把重点打出来
结论:
haines提到的终纹部分说:终纹从杏仁核的皮质内侧核群发出
ventral amygdalofugal 会从皮质内侧的中央核群及基底外侧核群发出
所以共笔21 p14基底外侧核群传出纤维为终纹,把它改成ventral amygdalofugal
虽然教官ppt p38的图(从haines来的) 终纹有画从皮质内侧核及基底外侧核出来,
但是haines课本没讲到。
