ON-OFF amacrine cells in cat retina

The Journal of Comparative Neurology, 1996
We studied the morphology, photic responses, and synaptic connections of ON-OFF amacrine cells in the cat retina by penetrating them with intracellular electrodes, staining them with horseradish peroxidase, and examining them with the electron microscope.

Responses to light of starburst amacrine cells

Journal of Neurophysiology, 1996
1. Starburst amacrine cells were studied using whole cell patch recording. Displaced starburst cells were labeled in rabbit retinas by intraocular injection of 4,6-diamidino-2-phenylindole. The retinas were isolated and maintained in vitro. The inner limiting membrane and Muller cell endfeet were removed mechanically from small areas above the ...

Branching Pattern of Amacrine Cell Processes

Nature, 1966
IN connexion with studies on the experimental phenomenon of spreading depression1, the histological structure of the chick retina is being examined in detail in our laboratory. One of the techniques used proved very suitable for observation of cell processes in the inner plexiform layer.

The many roles of starburst amacrine cells

Trends in Neurosciences, 2005
Starburst amacrine cells release two classical neurotransmitters, ACh and GABA. In a tour de force of paired-cell recording, Zheng et al. now show that the starburst cells are mutually excitatory during early development but mutually inhibitory in adult animals.

Cholinergic amacrine cells in the rat retina

Journal of Comparative Neurology, 1986
AbstractStaining of rat retinal wholemounts with a monoclonal antibody against choline‐acetyl‐transferase (ChAT) reveals two matching populations of amacrine cells in pigmented and albino rat retinae. One population has cell bodies in the inner nuclear layer (INL).

Dopaminergic amacrine cells in the cat retina

Brain Research, 1982
Autoradiographic studies of cat retina showed an accumulation of [3H]dopamine in a subpopulation of amacrine cells whose process ramify in the outermost stratum of the inner plexiform layer. Dendrites of these cells are characterized by numerous varicosities measuring up to 2 micron in diameter which are connected by fine intervaricose segments.

Amacrine cells of the rhesus monkey retina

Journal of Comparative Neurology, 1990
AbstractAmacrine cells of the rhesus monkey, Macaca mulatta, were studied in 38 retinas Golgi‐impregnated as whole, flat preparations. By using criteria of dendritic morphology, span of arborization, and level of arborization in the inner plexiform layer, 26 types of amacrine cell ranging in size of dendritic span from 30 μm to 2 mm were identified and

Kainate‐induced endocytosis in retinal amacrine cells

Journal of Comparative Neurology, 2003
AbstractEndocytosis is enhanced in some cases of neuronal death. We report for the first time that intraocular injections, in chick embryos, of excitotoxic doses of kainate induce strong endocytosis in retinal amacrine cells destined to die and that even subtoxic doses can induce some degree of endocytosis. That the uptake was due to endocytosis rather

Horizontal and amacrine cells in the mammal's retina

Vision Research, 1971
Abstract The study of the retina of several mammals by both light and electron microscopy shows the existence of two types of horizontal cells: horizontal cells with a short axon, and horizontal cells without axon, which we can name “amacrine” cells of the outer plexiform layer. The horizontal cells with a short axon are related to cones.

Amacrine cells of the rabbit retina

2022
The intemeurons of the inner retina, which Cajal called amacrine cells, are the most heterogenous class of retinal neuron, exhibiting a remarkable diversity of morphology and neurochemistry that underpins the complexity of retinal function. Using Neurobiotin tracer-coupling, the morphology, topographic distribution and dendritic interrelationships of ...
