Projections from visual cortical areas of the superior temporal sulcus to the lateral terminal nucleus of the accessory optic system in macaque monkeys

Tritiated amino acids were injected into the striate area and in single visual areas of the superior temporal sulcus (STS) of 7 cynomolgus monkeys, in order to trace visual cortical projections to the nuclei of the accessory optic system (AOS). Injections in STS separately involved the areas MT and MST, and resulted in labels within the lateral terminal nucleus of the AOS. In no case were labels found within the AOS nuclei in the brains injected in the striate area, or within the contralateral AOS. It seems likely that the areas MT and MST contribute signals--selectively related to visual motion processing--to the AOS, which is probably involved in the neuronal pathway subserving the optokinetic reflex.

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.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

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.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.
