Neural pathway key to sensation of pleasant touch identified (Links to an external site)
Zhou-Feng Chen, PhD, director of the Center for the Study of Itch & Sensory Disorders at Washington University School of Medicine in St. Louis, alongside his team, identified a neural circuit and a neuropeptide in mice — a chemical messenger that carries signals between nerve cells — that transmit the sensation known as pleasant touch from the skin to the brain.

A team led by researchers at Washington University School of Medicine in St. Louis has identified, in mice, specific cells and proteins that control the sneeze reflex. Better understanding of what causes us to sneeze — specifically how neurons behave in response to allergens and viruses — may point to treatments capable of slowing the spread of infectious respiratory diseases.
