10However, the functional role of many other retinal ganglion cell types cannot easily be disentangled in this way, prompting the need for a better method to distinguish these cells in the living eye.ġ/ − 1/power(D)} × 10 6, where the power in diopters has been calculated by linearly scaling eye size by the measured axial length. It has been possible to examine the different functional contributions of the parvocellular and magnocellular pathways to vision because they are anatomically segregated in the lateral geniculate nucleus (LGN), allowing psychophysical measurements in monkeys after selective lesioning. 7 ), and these studies must be supplemented by investigations in the living primate. The function of primate retinal ganglion cells has received detailed scrutiny recently with the use of in vitro methods (see, for example, Dacey et al. Detailed description of the morphology and physiology of primate ganglion cells have been carried out by Rodieck and Watanabe, 4Watanabe and Rodieck, 5and Dacey et al., 6 7 8 9resulting in the identification of more than 20 different retinal ganglion cell types. Imaging retinal ganglion cells is of special importance because it offers the possibility of directly observing the function of myelinated, spiking neurons of the central nervous system in the normal and diseased retina. Similar approaches may be applied to image other relatively transparent retinal structures, providing a potentially valuable tool for microscopic examination of the normal and diseased living retina. This in vivo method applied to ganglion cells demonstrates that structures smaller than the somas of typical retinal cells can be accessible in living eyes. The axial positional accuracy of fluorescence- labeled objects was approximately 4 μm.Ĭonclusions.
The full width at half maximum of the transverse line spread function (LSF) was 1.6 μm, and that of the axial point spread function (PSF) was 115 μm. Axons and dendritic arborization could be resolved in primate retinal ganglion cells in vivo, comparing favorably in detail with ex vivo confocal images of the same cells. Fluorescence images of the ganglion cells were obtained in vivo with an adaptive optics scanning laser ophthalmoscope. Macaque retinal ganglion cells were labeled with retrograde transport of rhodamine dextran injected into the lateral geniculate nucleus. The extent to which the fine structure of single ganglion cells, such as dendrites and axons, can be resolved in retinal images obtained from the living primate eye was investigated. The products are also exported to Middle East and SAARC countries.Purpose. The products are marketed through an All-India network of dealers and through its several branches all over the country. The company's major product is marketed under the brand name 'DENDRITE'. These products are mainly used in footwear, automobile, shipbuilding, railway coaches, engineering, electronics, leather goods, flooring, packaging, construction and household applications. The company manufactures and markets a variety of Synthetic Adhesives based on Polychloroprene, Polyurethane, Epoxy, EVA, Lamination and other Elastomers. The company has three factories in Kolkata. Chandra Group based in Kolkata.Ĭhandras' Chemical Enterprises (Pvt) Limited is the second unit of the Group which was set up in 1965. Production Company ĭendrite is produced by the Chandras' Chemical Enterprises (Pvt) Limited under the umbrella of the P. Its marketing slogan is Bonding our world together. Dendrite holds 80% of the market share throughout the country in footwear retail market. The adhesive is marketed in glue sticks, glue tubes and in cans.
