: delta-Baclofen reduced the peak amplitude of the barium current in the DSCs from Lunicuspis and L.fluviatilis. The membrane conductance was not altered either by baclofen or GABA. The reducing effect could be abolished with delta-aminovaleric acid or 2(OH)saclofen. The data obtained suggest presence of the GABAB receptors in the DSC membranes. Functional role of the GABAB receptors in primary afferent cells of cyclostomes, is discussed.
