By using the Golgi technique, the authors investigated the morphology of ganglion cells in the retinas of South American opossums. In flat-mount preparations of the retinas, cell bodies, entire dendritic fields, and the stratification level of ganglion cells were studied. Fractal dimensions of dendritic trees, an objective quantitative measure of(More)
PURPOSE To describe the electroretinogram of the South-American opossum (Didelphis aurita) obtained by chromatic stimulus of specific wavelengths. The electroretinogram records voltage variations of retinal cells triggered by light stimulation. The electroretinogram represents the combination of electric activity of many different cells and varies according(More)
Using the Golgi technique we investigated the morphology of the ganglion cells of the South American opossum retina. 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. Both radial sections of the retina,(More)
