A number of modern techniques now allow histologists to characterize subpopulations of retinal neurons by their neurotransmitters. The morphologies and connections of these chemically defined neurons can be analyzed precisely at both light and electron microscope levels and lead to a better understanding of retinal circuitry. The dopaminergic neurons form a loose population of special wide-field amacrine cells bearing intraretinal axons within the inner plexiform layer. One subtype, the interplexiform cell, sends an axon to the outer plexiform and outer nuclear layers. The number of interplexiform cells is variable throughout mammalian species. The GABAergic neurons form a dense and heterogeneous population of amacrine cells branching at all levels of the inner plexiform layer. The presence of GABA in horizontal cells seems to be species-dependent. Close relationships occur between dopaminergic and GABAergic cells. GABA antagonizes a number of dopaminergic actions by inhibiting both the release and synthesis of dopamine. This inhibition can be supported by GABA synapses onto dopaminergic cells, but GABA can also diffuse to its targets. Finally, GABA is also contained and synthesized in dopaminergic cells. This colocalization might be the basis of an intracellular modulation of dopamine by GABA.

The Social Security Administration is committed to providing the high quality of service the American people expect and deserve. In light of the significant growth in the number of disability claims and the increased complexity of those claims, the need to make substantial changes in our disability determination process has become urgent. We are publishing a final rule that amends our administrative review process for applications for benefits that are based on whether you are disabled under title II of the Social Security Act (the Act), or applications for supplemental security income (SSI) payments that are based on whether you are disabled or blind under title XVI of the Act. We expect that this final rule will improve the accuracy, consistency, and timeliness of decision-making throughout the disability determination process.
A mechanized system for the production processes planning involving the use of an electronic code device for data preparation on a punched tape of the "EPECT-IT" type, at the base of which there are classifiers of standard operations and transitions to individual design members, is considered. A fragment of the classifier and a skeleton diagram of the system are presented. It is pointed out that the use of the system helps improve the quality of the design work, as well as to yield considerable economic advantages. The system is in operation at some enterprises of the medical engineering industry.
