Magneto-fluctuations of the normal resistance R N have been reproducibly observed in YBa 2 Cu 3 O 7Àd (HTS) biepitaxial grain boundary junctions at low temperatures. We attribute them to mesoscopic transport in narrow channels across the grain boundary line. The Thouless energy appears to be the rel
