A technology of electrolytic lesion was used to destroy the projections of cerebellar FN neurons to hypothalamus in decussation of superior cerebellar peduncle.

电毁损小脑上脚交叉中顶核投射至下丘脑的神经纤维，然后再用生物素化葡聚糖胺顺行追踪观察小脑顶核-下丘脑之间神经元投射。

Results: It was observed that projections from IN to hypothalamus passed through the superior cerebellar peduncle, crossed in its decussation and then many of them entered posterior hypothalamic area by iontophoresis of Dextran-Texas Red to cerebellar IN. Using the methods of iontophoresis of Fluoro-Ruby and double labelling staining, it was also observed that the neurons projecting to PH in cerebellar IN were glutamatergic neurons.

结果：小脑间位核电泳Dextran-TR后示踪可见间位核神经元发出离核纤维，行走于同侧小脑上脚中，在小脑上脚交叉处交叉到对侧，然后继续走行于小脑上脚中，到下丘脑后较多纤维终止于下丘脑后区；在下丘脑后区电泳Fluoro-Ruby后可逆行追踪到小脑间位核神经元，荧光双标法显示投射到下丘脑后区的小脑间位核神经元中有谷氨酸能神经元。

Gene mutations were detected in 25 patients and a 18-year-old girl among 16 families. Trinucleotide repeats of CAG were 73～79. The fragments of abnormal alleles were 380～402bp, and all patients were heterozygous. The copy numbers of normal alleles were 18～40, fragments from 202～270bp. SCV reduction was much obvious compared to MCV, MCV and SCV in lower limb ?ere much more slow than that in upper's. BAEP, VEP were also delayed in latency. The anticipation in parental sex bias were much more obvioius than that in matental's. Cerebellar ataxia was most severe, the next were dysarthria and bulging eyes. Amytrophy was seen only in bed ridden patients. Cerebellar atrophy was more severe than brain stem, cord atrophy was n't observed in all MJD.

结果检出10个家系25例病人及1例症状前18岁女孩有MJD基因突变，CAG三核苷酸重复73～79次，异常等位基因片段长380～402bp，均为杂合子；正常人CAG三核苷酸重复18～40次，等位片段长200～270bp，电生理发现MJD的SCV减慢比MCV明显，而下肢的MCV、SCV又较上肢明显，BAEP、VEP均有不同程度的潜伏期延长或波的异常；MJD的父亲遗传早于母亲，进展也较块，临床以小脑性共济失调为突出症状，其次为构音障碍、突眼等，肌肉萎缩仅见于晚期病人；MRI示小脑萎缩较明显，脑干萎缩并不严重，未见明显的颈髓萎缩。

Objective: To study the changes of the intrinsic electrophysiological characteristics of cerebellar Purkinje cells during the stage of the elevation of intracellular Ca(superscript 2+) through micro-injected of IP3 receptor excitomotor of Purkinje cells in cerebellar vermis.

目的：通过向细胞内微量注射IP3受体激动剂诱发细胞内高钙，探讨细胞内高钙对小鼠小脑浦肯野细胞内在电生理特性变化的影响。

The results show as follows:(1) immunoreactive neurons of NPY in pigeon cerebellum tire mainly located in the Purkinje cell layer of the cerebellar cortex, especially in the top of Purkinje cell in cerebellar folia:(2) a few neuropeptide Y immunoreactive neurons are observed in the central nuclei of cerebellar white matter .which is different from silky fowl, chick and rat;(3) none of neuropeptide Y immunoreactive neurons are found both in the molecular and granular layer.

结果显示：(1)小脑内神经肽Y(neuropeptide Y，NPY)阳性神经元主要存在于小脑皮质的蒲肯野氏细胞层，且以小叶顶端的蒲肯野氏细胞阳性明显；(2)小脑白质中央核可见到少量阳性神经元，不同于乌鸡、肉鸡及大鼠；(3)分子层、颗粒层未见阳性反应细胞。

The myelinization of cerebellar white matter,middle cerebellar peduncles,anterior limb of internal capsule,splenium and genu of corpus callosum,centrum semiovale,the white matter in parietal-occipital area and frontal-temporal area were documented at birth to 5,2～4,3～7,3～5,4～7,2～7,3～9 and 4～12 months old,respectively.

髓鞘形成至成熟时间：小脑上下脚、桥脑背侧、丘脑腹外侧和内囊后肢后部出生时已成熟，小脑自出生至5个月，小脑中脚2～4个月，内囊前肢3～7个月，胼胝体后部、膝部分别是3～5个月、4～7个月，半卵圆中心2～7个月，枕顶叶白质3～9个月，额颞叶白质4～12个月。

Of the 26 lesions with pontine and bulbar involvement, three had no association with other lesions (Fig 2). Twelve were associated with tegmental and superior cerebellar peduncular extension, and six showed corticospinal tract involvement in continuity with an MDJ lesion. In one patient with additional telencephalic lesions, the right side of the pons was hyperintense on long TR/TE images that did not cross the midline, suggestive of an arterial lesion (Fig 3). In two patients with pontine tegmental lesions, there was an associated middle cerebellar peduncle and deep cerebellar white matter involvement (Fig 4). Two others had associated cervical lesions.

在26处脑桥延髓区病灶中，3处病灶仅限于脑桥延髓区，其它部位无病灶（图2）；12处病灶还同时伴有背盖部和小脑上脚/结合臂处病灶；6处病灶为与中脑-间脑接合处病灶相连的皮质脊髓束受累；还有1例患者除端脑见病灶外，右侧脑桥于T2像也见高信号病灶，但未超越正中线，提示可能系动脉病变所致（图3）；2例脑桥背盖部病灶的患者同时伴有小脑中脚/小脑脑桥脚和小脑深部白质受累（图4）；还有2处脑桥延髓区病灶还同时伴有颈髓病灶。

Cerebellar central stenosis, known as the cerebellar vermis; both sides of the expansion, called the cerebellar hemisphere.
