Dendritic field diameter and mean axon diameter of both parasol and midget cells showed significant correlations.
      
We have labelled individual retinal ganglion cells of a New World primate, the common marmoset (Callithrix jacchus) with neurobiotin and then measured axon, soma and dendritic field diameter.
      
The mean cell body and dendritic field diameters of 47 cells were 18.5 ± 1.6 μm, (size range 16-21 μm) and 91.5 ± 16 μm (range 54-133 μm), respectively.
      
We focused our attention on a type of ganglion cell which has a relatively small dendritic field diameter and a medium-sized soma, making it a morphological equivalent of beta ganglion cells of cat retina.
      
The following parameters of Purkinje cell dendritic trees were studied: dendritic field area, branching density, total branch length, spine density and total number of spines.

Morphology and development of dopaminergic neurons has been studied in the kitten retina, using tyrosine hydroxylase (TH) immunocytochemistry. TH immunoreactive (TH~+) cells are already presented in wholemount and sectioned retina at first postnatal day (P 1). Aceqrding to soma size, shape, dendritic process pattern and immunoreactivity, two classes, type I or large dark staining TH~+ cells and type Ⅱ or small light staining TH~+ cells are recorgnized. The TH Ⅰ cells which consisting of normal placed DA amacrine ceils, displaced DA amacrine cells and DA interplexform-like cells, graduately mature during postnatal development, while TH Ⅱ cells decrease quickly and throught disappear at P30.After eye opening TH Ⅰ amacrine cells, especially their dendrites develop quickly. The soma diameters increase from 11.8μm (P1) to 14.2μm (P30). The dendritic fields increase in size and complexity. At P1 the thick radiating dendrites emerge from the cell body with small or large "spines" and many growth cones. At P 13 the dendritic field is markedly enlarged and only a few growth cones can be seen on some stained dendrites. In addition, the dendritic spines are no longer appearent and they are a part of rudimentary rings. By P 30 the dendritic plexus of TH~+ dendrites and rings in the outmost part of IPL, typical of the adult cells, are complete. The influence of light on the development of DA cells after eye opening and the possibility of neurotransmetter changing are discussed.

本文报道用酪氨酸羟化酶(TH)免疫细胞化学方法研究猫生后发育期多巴胺(DA)能神经元的形态和发育。TH阳性反应的DA能神经元在生后第一天(P_1)的视网膜中已经出现。按形态学特征——胞体大小、形状、突起分层,以及免疫反应强度可分为THⅠ型和THⅡ型两类。THⅠ型是大的强阳性反应的DA能细胞,包括通常DA能无长突细胞、移位DA能无长突细胞和DA能类网间细胞。它们随发育年龄增长逐渐成熟。THⅡ型是小的弱阳性反应的DA能细胞,不随年龄而生长发育,相反在开眼(P_(7-10))后细胞数量明显下降,至P_(30)时完全消失。开眼后,THⅠ细胞除胞体增大外树突发育特别迅速。它们的胞体直径从11.8μm(P_1时)增大至14.2μm(P_(30)时),相应的树突野和分枝交叉也明显增加。P_1时,树突分枝少而直,末端有许多生长锥。在中央网膜的树突有棘状附属物。至P_(13)时生长锥减少,许多分枝交叉形成简单的网状,同时树突“棘”完全消失,可能发展为环的一部份。至P_(30)时,树突分枝在内网从层的外层形成复杂的网络,其间有无数与杆型AⅡ无长突细胞构成突触联系的环形结构,相似于成年者。在生后发育过程中,开眼后适宜光照对THⅠ细...

The development of pyramidal and glia cells of hippocampus in human fetus aging from four to ten months have been studied with Nissl′s and Goilg′s methods under light microscopy. The results show that (1) the density of qyramidal cells decreases and that of glia cells increases with increase of age, being negatively related (r=-0.89). The change is most obvious at the age between six and seven months ; (2) the volume of pyramidal cells increases with increase of fetal age and the time of evident increase is...

The development of pyramidal and glia cells of hippocampus in human fetus aging from four to ten months have been studied with Nissl′s and Goilg′s methods under light microscopy. The results show that (1) the density of qyramidal cells decreases and that of glia cells increases with increase of age, being negatively related (r=-0.89). The change is most obvious at the age between six and seven months ; (2) the volume of pyramidal cells increases with increase of fetal age and the time of evident increase is between eight and nine months ; (3) the processes of pyramidal cells can. be divided into two types, apical and basal dendrites. the apical dendrtes apper earlier and grow faster than the basal dendrites. and ramify repeatedly. The basal dendrites have more branches with less repeated r ramifications and show fan-shaped dendritic fields.

The localization and distribution of cholecystokinin immunoreactive neurons in toad retina were studied with immunohistochemistry ABC method. The results showed that of 183 CCK immunoreactive neurons observed, 85% were Type Ⅰ amacrine cells, another 12% of CCK positive cells were classified as Type Ⅱ amacrine cells, while 3% of the CCK positive cells had their cell bodies located in ganglion cell layer and were designated as displaced amacrine cells. The CCK-immunostaining processes appeared as punctate labelling...

The localization and distribution of cholecystokinin immunoreactive neurons in toad retina were studied with immunohistochemistry ABC method. The results showed that of 183 CCK immunoreactive neurons observed, 85% were Type Ⅰ amacrine cells, another 12% of CCK positive cells were classified as Type Ⅱ amacrine cells, while 3% of the CCK positive cells had their cell bodies located in ganglion cell layer and were designated as displaced amacrine cells. The CCK-immunostaining processes appeared as punctate labelling throughout sublamina 1~5 of the inner plexiform layer. An examination of retinal whole-mounts revealed that CCK-immunoreactive neurons were distributed throughout the center and periphery of the retina. The density of CCK-immunoreactive neurons was calculated to be 30 ± 2.3 cells per mm2. The dendritic fields of CCK-immunoreactive amacrine cells were observed to be either symmetrically or asymmetrically distributed about their somas. The symmetrical dendritic fields ranged in diameter of 90~200 μm by 60~110 μm, and the processes forming asymmetrical dendritic fieldsranged from 60 to 100 μm in length.
