Barrington’s nucleus neurons are transsynaptically-linked to both the bladder and colon. Fluorescent photomicrograph of a rat brain section at the level of Barrington’s nucleus labeled with pseudorabies virus expressing green fluorescent protein that was injected into the bladder (green) and pseudorabies virus expressing β-galactosidase (red) that was injected into the distal colon. Many Barrington’s nucleus neurons are labeled with both viruses. These appear as either yellow or orange (arrows) or cells the have a red nucleus and green cytoplasm (arrowhead).
