Dye-, tracer- and electrotonic coupling were studied independently in genioglossal (GG) motoneurons using intracellular recordings in in vitro brainstem slices from rats postnatal ages 1-30 days. The subpopulation of GG motoneurons were retrogradely labeled after an injection of dextran-rhodamine into the posterior tongue. Dye-coupling was studied with Lucifer yellow injected into 55 motoneurons and tracer-coupling with neurobiotin injected into 89 presumptive GG motoneurons. Of the motoneurons… CONTINUE READING
