Abstract

Entopeduncular nucleus (EPN) cells which project to thalamic and non-thalamic sites were identified by antidromic discharge. Each population of cells, projecting to the ventral anterior nucleus of the thalamus (VA), centrum medianum (CM), the lateral habenula (LHB), and the pedunculopontine nucleus (PP), was distributed throughout the nucleus. While some cells projected to more than one region, particularly VA and CM, collaterals were not found in most cells. STN stimulation suppressed firing of some EPN cells for 80-120 msec in both barbiturate anesthetized and cerveau isolé cats. Suppression of activity was detected in most EPN cells projecting to LHB (73%); of all cells in which suppression of activity was detected, 84% projected to LHB and 15% to VA.

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.

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.
