title: Dye and electrical coupling between frog motoneurons.
abstract: Coupling between lumbar motoneurons in the isolated frog spinal cord was studied by using intracellular recordings and intracellular injections of Lucifer Yellow CH. Physiological studies revealed intra- and intersegmental, short latency electrical interactions between many motoneurons. Injections of Lucifer Yellow into motoneurons that were found to be coupled electrically revealed intra- and intersegmental dye-coupling.
