Organization of the reciprocal connections between the subiculum and the entorhinal cortex in the cat: II. An electrophysiological study

The Journal of Comparative Neurology

Abstract

The projection of the entorhinal cortex (EC) to the subiculum (SUB) and the projection in the opposite direction from the SUB to the EC have been studied in the cat by using electrophysiological methods. Field potentials elicited by EC stimulation were recorded in the SUB. Different topographic distributions of the amplitude of the average evoked potentials (AEPs) were obtained depending on the place of stimulation along a lateromedial axis in the EC. Stimulation of the lateral EC elicited the largest AEPs in the septal part of the SUB whereas stimulation of the medial EC evoked maximal responses in the temporal part of the SUB. Field potentials evoked by subicular stimulation were measured in the EC; the topographic distribution of the AEPs was dependent on the place of stimulation along the subicular septotemporal axis. Septal SUB stimulation elicited the largest field potentials in the laterocaudal part of the EC whereas temporal SUB stimulation evoked maximal responses in the mediocaudal part of the EC. These findings indicate that a topographical organization exists in the EC-SUB connections and that these connections are reciprocal. Unit activity both orthodromically and antidromically elicited by SUB stimulation was reco...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.
