ERK positive cell mainly distributed at nucleus of solitary tract, ambigous nucleus, and positive fibers and cells mainly distributed at medullary visceral zone, nucleus of solitary tract and ambigus nucleus. These positive cells formed an isolated zone from nucleus of solitary tract via medullary visceral zone to SP5, which could be seen using immunohistochemical stain. Positive cells and fibers also distributed at the projection from pneumogastric nerve to the stem.

免疫组织学染色可见，阳性细胞主要分布于延髓内脏带的孤束核和疑核、阳性纤维伴随阳性细胞分布于延髓内脏带的孤束核区和疑核、呈沿孤束核经延髓内脏带至三叉神经脊束核的弧行带；在迷走神经向脑干投射部位也可见阳性胞体和纤维的分布。

Barrington's nucleus that located in the pontine dorsolateral tegmentum is an important site for controlling voiding in the mammalian brain and is often referred to as pontine micturition center. Barrington's nucleus sends direct projection fibers to the sacral parasympathetic nucleus in which parasympathetic preganglionic neurons innervating detrusor muscles of the bladder are distributed. Electron or chemical stimulation of Barrington's nucleus clicits bladder contraction and increases discharges of bladder postganglionic nerve. Conversely, lesion of the nucleus results in a permanent inability to empty the bladder. On the other hand, an area located just ventral to Barrington's nucleu has been reported to send projection fibers to the ventrolateral group of Onuf's nucleus in the caudal lumbar cord segments; the vetrolateral group of Onuf's nucleus is mainly composed of pudendal motor neurons innervating the external urethral sphincter muscle.

Barrington's核发出纤维投射至支配膀胱逼尿肌的骶髓副交感核，毁损该区可导致动物永久性失去排空膀胱的能力；而电刺激或化学刺激该区可引起支配膀胱的节后纤维放电增加和膀胱逼尿肌收缩。D区是紧邻Barrington's核腹侧的一团神经元，它发出纤维投射至腰骶髓Ounf核的腹外侧群，而Ounf核的腹外侧群主要是由支配尿道外括约肌的阴部神经运动神经元组成。

RESULTS In normal volunteers group, anisotropy measurements in white matter regions were significantly larger than that of gray matter regions, different white matter structures show different anisotropy degree, with the commissural neurofibers of white matter having the highest value, followed by projection fibers and association fibers.

结果 在正常组DTI显示灰质与白质区各向异性存在显著差异，不同部位的白质纤维束各向异性程度亦不相同，脑白质连合纤维各向异性程度最高，其次为脑白质的投射纤维，再次为联络纤维、丘脑、基底节区灰质核团等。

In summary, the present study revealed that Barrington's nucleus and D-region received direct projection fibers from the sacral spinal neurons in lamina I, parasympathetic nucleus and dorsal commissural nucleus; periaqueductal gray also received afferent projections from the lumbosacral spinal cord and sent projection fibers to the Barrington's nucleus and D-region.

上述结果说明：大鼠腰骶髓 I 层、骶髓副交感核和后连合核神经元发出的投射纤维直接终止于 Barrington's 核和 D 区内；导水管周围灰质也接受来自腰骶髓的投射纤维，同时发出纤维终止于 Barrington's 核和 D 区内。

Previous studies have revealed that the hypothalamus, medial preoptic area and bed nucleus of the strial terminal send projection fibers to Barrington's nucleus and/or D-region.
