Morphology and topography of on- and off-alpha cells in the cat retina

Abstract

Neurofibrillar staining methods were found to stain all alpha cells of the cat retina completely, that is the perikaryon, the axon and the dendritic branches. The dendrites of the alpha cells in vertical sections were found to be unistratified and to occupy two narrow strata in the outer half of the inner plexiform layer. This difference in branching level could also be observed in whole-mount preparations and it has been demonstrated in the preceding paper (Peichl & Wässle 1981) that it corresponds to the physiological on-off dichotomy. Thus the topographical distribution of on- and off-alpha cells could be studied. They are found to occur in about equal numbers. Both on- and off-alpha cell perikarya form a regular lattice and both lattices are superimposed independently. The dendritic branches of neighbouring alpha cells overlap and each retinal point is covered by the dendritic field of at least one on- and one off-alpha cell. The dendritic trees of on-alpha cells seem to have more small branches and are on the average smaller than those of off-alpha cells. The density of alpha cells was found to peak in the central area whence it continuously decreased towards the retinal periphery.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
