Bipolar neurons in rat visual cortex: a combined Golgi-electron microscope study

Journal of Neurocytology
A Peters, L M Kimerer

Abstract

Golgi-impregnated bipolar neurons in rat visual cortex have been examined by both light and electron microscopy. Bipolar neurons are encountered throughout layers II to V and are recognized by their spindle-shaped cell bodies and vertically elongate, narrow dendritic trees which may traverse the cortex from layer II to layer V. Although a single primary dendrite usually extends from each end of the cell body, two primary dendrites may extend from one pole, usually the lower one, and an additional short dendrite may emerge from one side. In the electron microscope gold-toned Golgi-impregnated neurons are seen to have folded nuclear envelopes and except at the poles of the cell body where the dendrites emerge, the nucleus is surrounded by only a thin rim of cytoplasm. Both the cell body and the dendrites form asymmetric and symmetric synapses. Usually the axon of a bipolar neuron arises from one of the primary dendrites and it soon assumes a vertical orientation, to either descend or ascend through the cortical neuropil. Some bipolar neurons have myelinated axons and only the initial portion is impregnated in Golgi preparations, but when they are unmyelinated the axons can be seen to form vertical plexuses and asymmetric synapses...Continue Reading

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.
