Dye and electrical coupling between frog motoneurons.
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.
