Quantitative studies of enhancement and suppression zones in the receptive field of simple cells in cat striate cortex

Abstract

The configuration and extension of enhancement and suppression zones were compared with the configuration and extension of on- and off-response zones across the receptive field of simple cells in cat striate cortex. The enhancement and suppression zones were determined by a dual-stimulus technique where a stationary flashing light slit produced activity against which activation profiles across the receptive field were plotted with a parallel stationary test slit. The activation profiles showed less variation in receptive field configuration than plots of on- and off-discharge zones. Whereas the number of on- and off-zones varied between one and five, the activation profiles showed at least three distinct subregions in the receptive field, i.e. a central zone with an adjacent oppositely responding zone on each side. The responsivity was clearly stronger in one of these proximal flank zones. An additional zone occurred distal to the strong proximal flank zone in 53% of the cells, and in 10% such a distal zone occurred distal to both proximal flank zones. There was good correspondence between the location of on- and off-discharge zones and the location of the enhancement and suppression regions, although some subregions seen in th...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.
